    I already have a fully-functional task management system built with HTML5, CSS3 (Flexbox/Grid), vanilla JavaScript, PHP, and MySQL. Users can sign up securely, create, read, update, and delete tasks, all from a responsive dashboard. What I need now is a focused enhancement: 1. Progress tracking • Each task should hold a 0–100 value stored in MySQL. • Display that value on the dashboard with a smooth, colour-accessible progress bar. • Users must be able to set or update the percentage while creating or editing a task. 2. Project-based filtering • Add a “Project” filter that lets users instantly narrow the visible tasks without reloading the page. • Keep URL parameters in sync so filtered views can be bookmarked or shared...

    I have created a small offline app and would like someone to optimize it. The app is designed to display connections between companies. I enter a company and employees, and I have several roles, such as managing directors with time periods, shareholders, and interpreters who were involved in the company’s formation. The main issue I am having is with the visualization. I would like to create a company organigram in which the company with the most connections is placed in the center, and the companies with fewer connections are arranged outward around it. The connections should be labeled so that the structure is easy to understand. It should also be possible to move the diagram with the mouse, zoom in and out by scrolling, and use a search field to look up a company. The organigram ...

    You will join our product team full-time to design, build, and maintain a real-time web application powered by Node.js and React. On the backend you’ll craft well-structured JavaScript services, optimise algorithms and data structures for speed, and handle event-driven flows with sockets, Redis, and WebRTC. On the frontend you’ll ship responsive React interfaces that consume those services smoothly. Our data layer runs on MongoDB, so you’ll model documents, tune queries, and manage indexing for performance and scale. Day to day you’ll touch every layer of the stack—from server-side architecture and deployment scripts to pixel-perfect components—so broad curiosity and independent problem-solving are essential.

    The WordPress marketing site that collects loan enquiries is finished; what I now need is the engine that sits behind it. Your mission is to take each form submission, evaluate it against a set of routing rules, and fire it off—via REST—to one (or several) lender partners, then surface the results inside the existing WordPress admin as a lightweight CRM. Core objectives • Build a reusable backend module in PHP (WordPress-native), though I’m open to Node.js or Python if there is a clear technical advantage. • Create and document integrations for multiple lender APIs (JSON/REST, OAuth or key-based). Each lender returns different field structures, so normalisation and robust error handling are essential. • Develop a rules-driven router: think loan amoun...

    I’m spearheading a new custom web application and want a developer who can guide the project end-to-end—from the first wireframe to production deployment and ongoing maintenance. The goal is a fast, responsive experience that feels effortless on any device, scales easily, and remains secure against common threats. Here’s what I’ll rely on you for: • Translating product requirements into clear technical architecture • Writing clean, well-documented code and setting up version control from day one • Integrating external APIs, databases, and any third-party services the product demands • Optimising performance, accessibility, and SEO fundamentals as you build • Thorough cross-browser and device testing, followed by systematic debugging...

    The design and code are ready; everything is in place. We just need to install the designs with minor adjustments to ensure smooth operation across all devices and to modify any unsuitable screens. Ideally, the developer should have experience with both iPhone and Android, and also be familiar with bank integration if needed. The design is ready and the code is ready — all files and code are prepared. We only need to implement the designs with small tweaks so the app works smoothly on all devices, and adjust any screens that aren’t suitable. The developer should have both an iPhone and an Android device, experience with bank integration if required, and know how to upload to the Apple App Store, Google Play Store, and Huawei AppGallery. We have 4 designs: - 2 in English: dark...

    I’m setting up a lead-generation campaign for a webinar and need the entire funnel built and automated. Here’s the flow I have in mind: • A mobile-friendly form captures each prospect’s name, email and phone number. • Every submission lands instantly in a Google Sheet for easy tracking and follow-up. • Once the form is completed, my pre-written WhatsApp message—containing a personalised Zoom link—is triggered and sent automatically. • If a payment step becomes necessary, I’d like the same workflow to hand the guest a UPI link and record the transaction status back in the sheet. I already have the exact WhatsApp copy; you just need to wire it in. Feel free to use the tools you’re most comfortable with—Google Apps Sc...

    I’m kicking off the creation of a brand-new web application and need a programmer who can guide the project from first commit to production release. You’ll take my concept and implement both the user-facing front end and the server-side back end, then deploy everything to a live environment. You are free to choose a modern tech stack—React, Vue, or plain JavaScript on the front end; Node.js, Django, or a comparable framework on the back end—so long as it results in clean, secure, well-documented code. Database design, API integrations, user authentication, and responsive UI are all part of the scope. I already have wireframes and a feature list ready to share once we start. Deliverables • Fully functional web application that matches the provided feature li...

    Hi, I already have a website design created and I want to replicate it on Shopify as closely as possible. I’m not looking to use a pre-made Shopify theme or drag-and-drop builder. I want a custom Shopify theme built using Liquid, HTML, CSS, and JavaScript so the design, layout, and animations match my existing website. The goal is to keep the website looking almost identical while making it fully functional with Shopify (products, cart, checkout, etc.). Please let me know if this is something you have experience doing and if you can replicate my design closely. I can share the current website and files with you.

    I’m building a small, self-contained web application that lets travellers pick their seats and buy bus tickets without refreshing the page or calling a back-end. Your job is to deliver the complete front-end in vanilla HTML, CSS and JavaScript, persisting everything with LocalStorage so the booking survives a browser refresh. Core flow • Users land on a responsive seating layout and can choose several seats in one go. • A passenger form then collects name, contact details, ID proof and age for every seat. • When the form is submitted, the user is taken to a separate summary page that lists each seat, passenger data and the total price, all drawn from LocalStorage so it can be revisited or printed. Acceptance criteria • Seat map visually reflects availability...

    Urgent PHP Gold Price Scraper
    6 days left
    Verified

    I need a quick-turnaround PHP script that pulls the live gold price from three different publicly accessible websites (no authentication required). The current feed I rely on has gone down, so this will act as an immediate rescue solution. Key requirements • Parse each site’s HTML/JavaScript to extract the latest price. • Merge the three readings into one final value (average or last-in wins—whichever is fastest to implement). • Refresh the value every 30 seconds and write it to a variable or simple cache file I can echo anywhere on my site. • Code must be plain PHP (I edit in Notepad++), well-commented, and ready to drop into an existing page. Timing is critical: I need the working script delivered within 30 minutes of awarding the project. If you...

    I need a lightweight Discord bot that does one job very well: fetch a list of URLs from a Google Sheet, check each one every 2-3 minutes, and report its current state—“Active” when the link responds, “Inactive” when it does not show open correctly—inside a designated Discord channel.
