Senior Automation Engineer for Traffic Simulation & Referrer Spoofing I am looking for a specialized Automation/Growth Engineer to build a custom Traffic Orchestration System. The goal is to simulate "Viral" traffic spikes to specific URLs to test search engine ranking signals. The Technical Challenge: This is not a simple headless browser task. You must solve the problem of taking high-volume, raw human traffic (via Pop-Under/PPV APIs) and "cleaning" it through a Bridge/Redirect layer to spoof specific social referrers while maintaining session integrity. Core Deliverables: - Referrer Bridge: Build a script/server that receives raw hits and uses a "Double Meta Refresh" or similar logic to spoof (e.g., masking traffic to appear as if it's coming f...
I need a blazing-fast, fully responsive online store built with and Tailwind CSS. Use whichever backend stack—Node.js or Python—helps you move quickest, pairing it with either PostgreSQL or MongoDB for data storage. The project must deploy cleanly on Vercel (Netlify is fine too) with seamless CI/CD. Core requirements • Server-side rendering plus rich Schema Markup so products surface on Google immediately. • Image delivery through Cloudinary with automatic compression and responsive breakpoints. • Secure checkout via Razorpay or Stripe, covering the full order lifecycle—cart, payment, confirmation, refunds. • Google Analytics 4 events for product views, add-to-cart, checkout start, and purchase. • An admin panel to add and edit product...
I need a sharp pair of eyes on my existing n8n workflow. A few of basic errors are stopping the automation from completing, and I’d like someone who knows their way around n8n’s editor to jump in, diagnose, and patch them quickly. I already have the error messages on hand and will share them as soon as we connect, so you can go straight to reproducing and resolving the issue. Scope • Identify the root cause of each reported error. • Adjust node settings or workflow logic so the flow executes end-to-end without throwing exceptions. • Walk me through what you changed so I can maintain the workflow myself in the future. Deliverable An updated .json export of the workflow plus a short summary of fixes applied—and, of course, a run that completes succe...
I need a full-stack developer to build a website in Node.js that cleanly presents three core areas—business listings, a blog section, and a product showcase—supported by a secure admin panel. The admin area must let me create, update, and archive content for each of those modules using a straightforward email-and-password login flow. Visual direction is modern and minimalist: lots of white space, clear typography, subtle accents, and a layout that feels snappy on both desktop and mobile. I’m happy for you to pick the most suitable Node.js framework (Express, Nest, Next, etc.) and database, as long as the code is modular and easy for another developer to pick up later on. Key deliverables: • Responsive public site with the three content sections wired to dynam...
I need an OpenAlgo environment wired up to Kite Connect so the system can place and manage an options straddle on the Indian markets with an integrated delta hedge. The core logic is already outlined—I simply want it coded, tested, and ready to push live. Here’s the flow I have in mind: • At a scheduled entry time the program selects the ATM call and put, and th corresponding predefined hedges, fires simultaneous market orders through Kite, and records the positions. • The delta hedge continuously checks net delta and sends offsetting futures orders whenever the threshold I set is breached. • Stop-loss, profit-target, and end-of-day square-off rules must sit server-side to survive a local outage. • All trades, greeks, and P&L should stream to a li...

I’m looking for a developer who can build a social-networking web application from scratch. The core idea is to let users create profiles, post updates, follow friends, and exchange private messages—nothing overly complex at first, but the foundations should be solid enough to grow. Here’s what I need delivered: • A responsive front end (React, Vue, or similar) with clean, modern UI components for feed, profile, and messaging. • A secure back end (Node.js, Django, or comparable framework) that exposes RESTful endpoints and handles authentication, user relationships, and real-time notifications. • A lightweight admin panel to moderate content and manage users. • Deployment scripts or documentation for hosting on a mainstream cloud platform (AWS, ...
My service company relies on SupplyPro for job intake and Housecall Pro for field operations. To eliminate double-entry, I need a lightweight interface that pulls new or updated Job details and Scheduling data from SupplyPro every day and posts them into Housecall Pro through their public API. Scope • Build or configure a script, micro-service, or low-maintenance middleware that can be scheduled to run daily. • Map SupplyPro fields to the corresponding objects in Housecall Pro—job name, description, appointment date/time, technician notes, and any other essentials we identify together. • Handle basic data-format compatibility so nothing breaks if SupplyPro formats dates, phone numbers, or addresses differently. • Provide clear, commented source code plus ...
I need to move my live React-based website from its current host to a new server and want the transition to be completely seamless for users. The job covers copying the full codebase or production build, recreating environment variables, configuring Node.js and a web server such as Nginx or Apache on the destination machine, migrating SSL, pointing DNS to the new IP, and confirming that every page, route, and API call works exactly as before. Deliverables • Site running flawlessly on the new server, accessible over HTTPS • Step-by-step documentation of the migration and any configuration changes • Quick rollback or recovery plan in case we need to revert I will open a low-traffic window for the switchover so downtime stays near zero. Let me know what access or prelim...
The idea Implement an API whose goal is to produce routes that are: - 100% drivable (Directed & Drivable) - Truly diverse (not just different geometry) - Geometrically stable, with no stitching issues or incorrect direction reversals - Close in performance and behavior to Google Maps / Waze (very important) What I’m specifically looking for I’m looking for a developer who understands road networks as real graphs, not just as lines drawn on a map. The right person must be comfortable with: - Directed graphs - One-way roads & carriageways - Edge-based diversity - Geometry correctness Current required tasks (very important) Implement a single API endpoint that returns multiple routes: 1 - The natural route (Google/Waze-like): - Fastest / shortest path - Acts a...
I’m ready to turn into an engaging, browser-based hub where independent artists upload original tracks, visitors stream them, and real-time votes decide who earns a live beach concert. The entire experience must happen on a responsive website—no separate mobile app for now—so performance on phones, tablets, and desktops is essential. Core experience • Users create an account or sign in with a social profile, start listening immediately, and see each track’s score climb or dip the second a vote is cast. • A single click lets them share the song or their own vote on major social platforms to keep the buzz growing. • Behind the scenes I need an intuitive admin area to upload songs, open or close voting rounds, spotlight weekly leaders, and export...
Overview I’m launching a ride-hailing app (Uber-style) focused on London. This is an MVP, not a massive rebuild of Uber. I am looking for an experienced mobile app developer or small team who has already built ride-hailing / taxi / delivery apps (or very similar).

I own a garage website currently sitting on my GoDaddy hosting. The code base is Custom HTML/CSS and, unfortunately, the original developer is now charging extortionate fees while keeping hold of the files and database. I need a skilled web developer who can: • Scrape or export every line of code, text, and image from the live site • Re-create the database so I regain full control of customer bookings and quotations • Deliver an enhanced design—fresh look, modern UI, fully mobile responsive • Add a dedicated HGV calendar so lorry MOT slots can be managed separately from standard vehicle work • Integrate Elavon for secure online payments alongside our existing booking and quoting flow The current system already lets customers book repairs and request...
I already have a working integration file from my gaming website and now want a Telegram bot wrapped around it. The core of the job is to turn that file into a smooth chat-based experience where a user can: • open a brand-new account • log in and retrieve their session • make a deposit through the existing payment flow • call up balance, game stats or any other info the site normally shows All endpoints and parameters are defined; you just need to plug them into a Telegram Bot API build, handle the usual checks (input validation, error messages, session tokens) and push back responses in a clean, user-friendly format. I will hand over: – the full integration script with endpoint references – test credentials and a staging bot token – a s...
I’m ready to launch a full-featured social networking web application and need a developer who can take it from concept to production. The core experience revolves around three must-have features: rich user profiles, a real-time messaging system, and an engaging activity feed that keeps everyone up to date on posts, likes, and comments. The site has to be entirely browser-based, mobile-responsive, and built with clean, well-documented code. I’m open to the modern stack you prefer—whether that’s React or Vue on the front end, a Node/Express, Django, or Laravel backend, and a solid relational or NoSQL database—so long as it scales, is secure, and performs smoothly under load. Deliverables I expect: • Wireframes or a clickable prototype to confirm UX...
I need a small, self-contained script that signs in to NetSuite through the appropriate API (SuiteTalk, REST Web Services, or a RESTlet—whichever you feel is the most secure and sustainable) and then downloads a specific report whose URL I will feed in as a parameter. The output must always be saved in CSV format; no other file types are necessary. Configuration items such as account ID, credentials / OAuth tokens, and the report link should sit in an external file or clearly marked variables so I can update them without touching the core logic. When you hand it over I expect: • A working script with clear inline comments. • A brief README explaining any required libraries, token generation steps, and how to invoke the download with a new report link. If you ha...
Please Read Carefully Before Applying It does not matter whether you consider yourself a “vibe coder” or a traditional software engineer we accept both here. What matters is whether you can make this system work reliably at scale. We operate a production scraper that processes 500+ leaderboard sites per hour. All sites we scrape are leaderboards, but no two sites are the same. This is not a basic scraper. What Makes This Scraper Different The leaderboards we scrape vary heavily in structure and behavior: Dynamic buttons, tabs, and switchers JavaScript-rendered content Hybrid navigation (UI interaction + background API calls) Tables, card layouts, podium layouts, or combinations of all three Masked usernames and inconsistent rank formats Different ordering of wager / prize data ...
PROJECT: AI-POWERED CONVERSATIONAL DOCUMENT CLOUD ACCESSIBLE VIA WHATSAPP 1. Overview The project consists of creating an intelligent document cloud, accessible primarily through WhatsApp, where users can ask anything related to the company (machines, documentation, spare parts, regulations, internal data, etc.), and the AI automatically returns the correct information, either as a text response or by delivering the exact PDF document required. This is not a traditional app and not a simple chatbot. It is the living memory of the company, organized in the cloud and accessed conversationally. 2. Entry Point: WhatsApp WhatsApp is the only access channel. The phone number identifies the user. There are no usernames or passwords. The system automatically recognizes: The phone number T...
I’m putting the finishing touches on a revenue-focused dApp running on BNB Smart Chain and need a full-stack Web3 specialist who can take ownership of both Solidity contracts and a front end over the next three months. What I still need: • Fresh smart contracts for a multi-level referral engine that automatically promotes users through tiered levels, plus staking/vesting logic, a level-gated NFT mint function, and an ATA utility token. • Seamless integration of those contracts into my existing TypeScript/ codebase using Wagmi ( or are fine substitutes), including wallet connection and real-time state updates. • A sweep of the current front end to squash bugs, fill missing features, and polish UI/UX and transaction handling so users enjoy a smooth, low-friction f...

Our production platform is already live on CodeIgniter (MVC) with a Bootstrap front end, Ajax-heavy JavaScript, a MySQL/SQL back immediate need is to improve code maintenance so the application can scale cleanly while we continue to ship new functionality. What needs to happen: • Track down and resolve outstanding bugs that affect both the customer dashboard and admin area. • Build out several new features now on the roadmap, using the current CodeIgniter architecture but written cleanly enough to migrate later to Laravel or a Node.js micro-service. • Refactor brittle controllers, models, and SQL queries for faster response times and lower complexity.
I am looking for a lead developer to architect and build a scalable "Sustainability-as-a-Service" platform. The core of the product is a high-performance API that will be integrated into the checkout flows of major e-commerce and delivery platforms to facilitate real-time environmental impact (tree planting) with every transaction. The core challenge is two-fold: High-Volume API Integration: We need a robust backend capable of handling thousands of concurrent requests from enterprise-level partners. The system must process transaction data, trigger fulfillment requests, and maintain 100% data integrity. The Transparency Layer: Our unique value proposition is verifiable proof. You must build a database and front-end dashboard that stores and serves geotagged data (GPS coordinat...
I’m looking for a Playwright-based framework that automatically exercises our REST and GraphQL endpoints against the staging environment. The goal is a maintainable suite that can be triggered on every build and gives us fast feedback before we promote code to production. Here’s what I need: • Comprehensive Playwright test scripts that cover core flows such as login, key form submissions, and common data-validation scenarios (I’ll provide the exact endpoints and payloads once we start). • A clear way to parameterise base URLs so I can later point the same suite at local or production environments without code changes. • HTML/JSON reports generated after each run and stored in a folder I can archive in the CI pipeline. • Step-by-step documentati...

We are seeking a high-level Full-Stack Engineer to finalize a premium Email Marketing & Automation platform. The UI/UX is approximately 85% built (both Light & Dark modes are complete), but we are moving on from a previous developer due to poor code quality, lack of documentation, and a lack of attention to detail. We need this production-ready in 14 to 30 days. We are looking for a "finisher" who can deliver clean, documented, and high-performance features daily.

I’m building a live remote-monitoring dashboard that ingests MQTT messages from a teltonikak rtu 901 gateway along with temperature, pressure, and oxygen sensors and many other parameters from a controller. The stack I have in mind runs on DigitalOcean or AWS and is driven by Python on the back-end and JavaScript on the front-end, but I’m happy to discuss refinements if you can justify them. Current status • Devices is yet to publish raw readings over MQTT. • No cloud pipeline, storage layer, or UI exists yet. What I need next • A lightweight yet secure ingestion service (Python is preferred) that subscribes to the topics, validates payloads, and writes them to a scalable store on DigitalOcean. • A real-time dashboard in JavaScript that shows live ...
I need a solid backend that lets several independent restaurants run from the same cloud platform while keeping a local MySQL database at each venue. The stack is already set: Node.js on the server side, Angular for the web console, and standard SQL. Core features I must see working: order management that mirrors every ticket and status update in real time, a secure user-authentication layer (roles for cashiers, kitchen, managers, etc.), and inventory tracking that updates stock counts the moment an item is sold or a delivery is recorded. Each restaurant keeps operating even if its connection blips, so a lightweight web service will sit on the local machine, watch the MySQL tables, and push changes to the cloud API the instant they happen; the cloud then replies with any new data to ...
I’m midway through a software development project and now need to fold in a fully-fledged user authentication layer. The current codebase is stable and organised; what’s missing are the sign-up, log-in, password reset, and basic role-based access controls that will make the product production-ready. You’ll be working against an existing Git repo. I’ll grant access and walk you through the structure so you can slot your changes in cleanly rather than bolting them on. I’m open to the usual approaches—JWT sessions, OAuth, or any secure flavour you’re most comfortable with—as long as the solution is standards-compliant and easy for another developer to pick up later. Deliverables • Registration, log-in, log-out, password reset flows ...
I need a lightweight, browser-based application that lets customers quickly find and book trusted home-service pros—starting with cleaners—through a clean, Uber-style interface. The whole experience must feel effortless for users who may not be tech-savvy, so every screen has to be uncluttered, with large touch targets, clear typography and a gentle colour palette. Core workflow • A new customer lands on the site, registers with a phone number and receives an SMS code to verify the account. • They browse service-provider cards that show a photo, short bio, skill tags and an aggregate star rating pulled from past jobs. • From the same view they tap a date/time slot, confirm the booking and immediately see it in their personal schedule. • A lightweigh...
The task is to turn my early-stage concept into a working hybrid MVP that will launch first on the web. Everything else in the product can stay bare-bones for now—the priority is a clean, secure user-authentication flow that covers sign-up, login, password reset and session handling. Social or single-sign-on options (Google, Apple, etc.) would be great if they slot in easily. I have user stories and low-fidelity wireframes ready. Choose any modern stack you’re comfortable with—React or Vue on the front end, Node/Express, Django or a similar REST backend, paired with JWT or OAuth for token handling. What matters is that the codebase remains portable so I can wrap it later with Capacitor, Ionic or another bridge for iOS and Android. Deliverables • Deployable web bu...

I need a complete, student-facing web application that lets users prove the authenticity of their academic certificates through blockchain hashing. The flow is straightforward: a student signs up, uploads a certificate, and immediately receives an on-chain validation record that anyone can later cross-check online. I have half work done and pages are created Core functionality • Secure user registration and login with email or social auth • Certificate upload, automatic hashing, and immutably storing the hash on a blockchain network (Ethereum or any suitable L2 you recommend) • Instant on-screen validation result plus a shareable verification link • Admin dashboard where I can review submissions, view analytics, and revoke or re-issue hashes when needed Tech...
I maintain a Node.js / TypeScript code-base that submits Jito bundles to the Solana network at high frequency. The current version works, yet under heavy load it saturates network bandwidth, slows slot confirmation, and leaves a larger attack surface than I’m comfortable with. I’d like you to jump in, profile the pipeline, and return an implementation that is measurably better across three axes—performance, scalability, and security. What performance means here is simple: bundles must reach the leader faster so more of them land profitably.
