My website already runs on a JavaScript front-end, but the current server-side rendering is spotty—some pages arrive half-rendered or drop key components altogether. I need a developer who can refactor the SSR layer so every page consistently ships fully rendered HTML to the browser before hydration, no matter the device or browser version. Once the rendering pipeline is solid, I want the site’s organic visibility strengthened. That means: • Dynamic keyword-driven titles, headings, and schema that pull from our CMS • Clean, unique meta tags and descriptions injected at render time • Page-speed wins that are easy to prove—compressed assets, smart caching, and any low-hanging performance tweaks you spot Acceptance criteria • No incomplete or inc...

We have a binary trading website with a working graph, but we want to improve its performance and fix some issues. The goal is to make the graph smoother, more responsive, and professional like top trading platforms. Tasks: 1. Optimize Graph Smoothness: • Make real-time updates smooth without jumps or lag. • Use incremental updates instead of full re-rendering. • Improve animations using requestAnimationFrame or similar methods. 2. Improve Performance: • Limit the number of candles loaded for efficiency. • Compress or aggregate older data for smoother scrolling. • Ensure fast rendering even with live data updates. 3. Bug Fixes: • Fix price jumps or candle overlaps. • Resolve any WebSocket or data feed issues. • Sync server and clien...

Hello, I have very simple wordpress site which we already passing core web vitals for mobile devices, we have litespeed web server and quiccloud CDN. But for desktop device we are failing due to CLS. We already score 90+ on google page speed score. I don't need developer who just install plugins and says job done, I need someone with real knowledge and can fix this issue precisely. I have tight and small budget, if you do great job, don't worry about good feedback from me and I have 20+ websites for core web vitals optimization and long term job for this. Thanks!

I keep getting the message “The action cannot be completed because the other program is busy” on my Windows machine and it’s driving me crazy. The alert pops up constantly—there’s no single app I can link it to—so I need someone who can dig in, trace the root cause, and stop it for good. You’ll have remote access to the computer to run diagnostics, inspect event logs, check for stuck COM or DDE calls, and rule out background services or conflicting startup items. Once the culprit is identified, I expect the fix applied, a short summary of what was wrong, and clear steps I can follow if it ever re-appears. Deliverables • Root-cause report (brief but specific) • Applied fix with confirmation the alert no longer appears after a reasona...

My WooCommerce store looks great, yet Google Lighthouse keeps flagging it for slow page load and inefficient resource use. I already run a caching plugin and multiple optimizations, but it clearly isn’t enough—especially because the site is reaching around 70-80 in google lighthouse Here’s what I need from you: Optimize the post pages and the product pages to reach 90-100 on google lighthouse. Keep the workflow transparent, I have backed up everything and you can directly work in production Here is the website https://xn--80abdexbacmj8a3a8e.xn--90ae/

I recently purchased a commercial Laravel starter kit and have run into two main pain-points: certain features break during specific user actions and overall performance drags under load. I need an experienced Laravel developer to dive into the repository, trace the root causes, and ship clean, tested fixes. Here’s what I’m dealing with right now: • Functionality issues surface only when particular workflows are triggered (for example, navigating deeper into authenticated areas, saving complex forms, or hitting AJAX endpoints). Your task is to audit the codebase, locate and repair the offending logic, then optimise any queries or middleware that are slowing things down. I’m already set up with Git, so you’ll work in a separate branch, commit frequently, a...

My SaaS-style web platform is already about 90 % complete; what I need now is a seasoned full-stack developer who excels at stepping into an existing codebase and driving it across the finish line. The top priority is thorough bug fixing and system testing. I expect a balanced mix of manual exploration and automated test suites so we can catch both edge-case glitches and any regressions before launch. Scope of work • Run a full test pass, document defects, and patch them. • Validate and, where needed, correct the usage-limit logic that controls free vs. paid quotas. • Polish the UI for mobile, tablet, and desktop breakpoints so every component renders cleanly and responsively. • Integrate the remaining ad slots and confirm the affiliate and withdrawal flows func...

My Supabase-backed web application needs a solid, automated maintenance routine. The core of the project is to keep the database healthy and fast, so I want complete coverage for three areas: regular backup and reliable recovery paths, performance tuning that actually shaves time off the heavier queries, and a clean workflow for applying Supabase/PostgreSQL updates and security patches without downtime. I already have the project running on Supabase; what’s missing is the living set of scripts, schedules, and monitoring rules that turn ad-hoc admin work into a predictable process. You’ll work directly in Supabase (and the underlying Postgres layer) and can bring in any complementary tooling—pg_dump, cron, pgBouncer, Grafana, or similar—as long as it integrates smoo...

My existing Power BI report pulls several large tables from Microsoft Dynamics 365 Business Central through the standard API. The model works, but the scheduled refresh now fails with frequent time-outs; reliability is my biggest concern. So far I have: • enabled incremental refresh on the largest tables • tuned a handful of queries • experimented with splitting data into smaller API calls None of these measures has eliminated the failure. I need an expert who can: 1. pinpoint the exact bottleneck within the current data model, gateway settings, or API calls 2. redesign the retrieval strategy so the report finishes every refresh window without timing out 3. leave me with a clean, documented PBIX (or dataflow) that follows best practice for query folding, pa...

I’m refining an existing EdTech platform whose backend is built on Laravel and whose user-facing layer runs on Angular. I need a full-stack developer (7+ years of experience ) who can slip into the current codebase, resolve a handful of blocking bugs, and then roll straight into feature work and performance tuning. Ability to convert functional requirements into technical requirements, familiarity with API integrations, AI and automations is a must have. Deliverables • Fix the critical issues • Implement the new features and enhancements • Provide ongoing support Weekly commitment of 20hours/week.

The codebase is a React front end that relies on Supabase for authentication, data storage, and real-time updates. A series of stubborn bugs have crept in—misfired auth callbacks, occasional data mismatches after writes, and visibly broken UI states when the websocket drops. Your first mission is to isolate and eliminate those issues so the app runs cleanly, with no console errors and all existing unit tests green. Once the core bugs are gone, I’d like a quick pass on the database schema (a couple of tables need index tweaks and a foreign-key adjustment) and help preparing a production deployment workflow. The stack is already wired to GitHub; I deploy to Vercel, but I’m open to your preferred routine as long as rollbacks are painless. Everything needs to be wrapped up ...

I need Cloudflare configured so my site automatically blocks malicious or nuisance traffic rather than legitimate visitors. The immediate headache is spam-driven form submissions and crawlers hammering the same pages hundreds of times a minute, so the goal is to stop those two behaviours without slowing genuine users. I already have a Cloudflare account in place; what I’m missing are the right firewall rules, bot management settings, and rate-limiting thresholds. You’ll review my current WAF/Bot Management setup, identify the loopholes that allow automated form posts and excessive page requests, then implement Cloudflare features such as Bot Fight Mode, custom WAF rules, Challenge or Turnstile for forms, and sensible request limits. Deliverables • Documented list of ...

I have a working script that only finishes when it can grab more than 100 GB of RAM. Right now I keep it online by renting several VPS instances, which already drains well over $500 every month and still doesn’t let me scale efficiently when workload spikes. I’m absolutely open to revisiting the way the program uses resources. What I need first is a sharp mind that can study the current setup, pinpoint where memory is wasted, and outline a smarter resource-management strategy. Whether the answer ends up being sharding the job across nodes, streaming data in smaller chunks, redesigning the in-memory structures, or off-loading parts to a managed cloud service, I’m ready to explore it—as long as we end up with a solution that scales without blowing up the budget. ...

I already have a functioning codebase that reaches Amazon endpoints, but I now need to harden and streamline the network layer. The top priority is Optimized Proxy Deployment: spinning up several proxy servers on AWS, each tied to its own Elastic IP and placed in regions nearest to the Amazon infrastructure we query. The target footprint is roughly 100 static IPs—half reserved for one domain and half kept in a common pool. Every outbound call must rotate to the next address so no two consecutive requests share the same IP, keeping average round-trip latency between 150 ms and 300 ms. When Amazon responds with a 429, the system should swap both the IP and candidateId instantly, with zero observable delay to the application. A second goal is lowering the overhead around our creat...

I’ve just purchased a Windows-based desktop for my apartment in the West Village and need a technician who can handle the full hand-over from my aging machine to the new one—about 200 MB of data in total. The job is straightforward but I want it done right: transfer all of my documents, personal files, and any system settings or preferences that will make the new PC feel instantly familiar. Because I’m not locked into a particular migration tool, I’ll rely on your recommendation for the most reliable software or direct-connect method. Once the copy is complete I’d like you to walk me through a quick check so we can confirm everything opens correctly and that user profiles, desktop layout, and network settings have carried over. Deliverables • Unbox or...

My VPS on Hostinger’s KVM line has started to crawl and I can’t pinpoint why. I’m looking for someone who already knows their way around the Hostinger panel, KVM virtualization, and typical Linux performance-tuning tools to jump in, diagnose the bottlenecks, and restore normal speed. Scope • This is strictly troubleshooting and ongoing maintenance; the server is already live. • The main pain point is degraded performance—slow response times under even light traffic. No connection drops or software errors have shown up, only sluggishness. • I need action right away, so please be ready to begin as soon as access is granted. Deliverables - A clear diagnosis of the root cause (CPU, I/O, memory, network, misconfiguration, etc.). - Applied fixes...

I already have a working Python-based OCR pipeline that converts Tamil voter-list PDFs into Excel, then pushes the sheets to S3 for further processing. The PDFs are purely image-based. When I run the job in parallel on AWS today, the script sometimes skips entire voter entries and often mangles door numbers and other data. I need these two pain-points eliminated and the whole flow hardened so it can run unattended across hundreds of constituency files. Optimising to the least cost of Extraction in AWS bill is also required. Your task is to review and refactor the existing code, tune the Tamil OCR (Tesseract, AWS Textract, or any library you find more accurate), modify the parsing logic, and make sure parallel execution on my current ECS setup completes without a single missed record. Onc...

I have a live mobile app on both iOS and Android that needs a full refresh. My priorities span three areas at once: • Sharpen the User Interface so the screens feel modern, consistent and intuitive. • Optimise Performance—faster load times, smoother animations, lower memory use. • Add a short list of new features that I will share once you have reviewed the current build. I’ll give you access to the existing repositories and an overview of the current architecture. After an initial code and design audit, I’ll need a clear action plan with milestones, then iterative builds I can test on TestFlight and internal Android tracks. Deliverables 1. Updated source code with in-line comments and a brief change log. 2. New UI assets integrated and pixel...

My desktop and laptop have both become sluggish and unstable. Outlook is now crashing several times a day and I suspect the 30,000-message mailbox is the chief culprit. I want to bring that mailbox back under control by archiving older threads, deleting anything truly unnecessary, and then re-optimising Outlook so it launches and searches quickly again. While we are at it, both machines have hit their disk-space limits. Google Drive and OneDrive are syncing far more files than I actually need offline, and the growing local cache is eating the last gigabytes on each device. I’d like you to review the sync configuration for both platforms at the same time, ensure only the essential folders stay local, and confirm that SharePoint libraries linked through OneDrive are also syncing prope...

I’m starting a fresh Minecraft Survival server and already have the hosting and premium plugins covered on my end. What I need now is an experienced hand to turn this blank canvas into a polished, one-of-a-kind world players will remember. The work revolves around full configuration and fine-tuning: installing the chosen plugins, balancing them so gameplay feels natural, setting up permissions, economy, crates, ranks, and any quality-of-life add-ons that elevate a Survival experience. I’m looking for creative ideas too—custom messages, unique spawn layout guidance, maybe a few bespoke scripts or configurations that differentiate us from every other “copy-paste” server. Performance matters. I’d like you to optimize the backend (paper/spigot/purpur, your...
