I’m looking for a developer who can jump straight into my existing site, pinpoint the root cause of a lingering problem, and implement a clean, reliable fix. The exact nature of the issue will become clear once you review the code and front-end behaviour with me in a quick screenshare or staging environment; right now, I simply know that something isn’t working as intended and it needs to be resolved fast. some of the issue: with unminified JavaScript and CSS files have low text-HTML ratio with blocked internal resources in and more.
I run a data platform built on Spark and Python, and I need an experienced engineer who can sit with me in Pune three to four times a week (hardly 2 hours in a day) to keep it running smoothly. Most of the immediate work revolves around tracking down bugs in existing PySpark jobs, but the role naturally extends to writing fresh code when gaps appear, tightening our data-pipeline orchestration, and mapping end-to-end data lineage so every downstream consumer stays confident in their numbers. Typical day-to-day work you will tackle: • Debug production PySpark jobs and accompanying Python utilities • Refactor or rewrite modules where quick fixes will not suffice • Optimise and monitor pipeline schedules (Palantir Foundry) • Document lineage and hand off clear, repro...

I’ve just finished deploying a new Android mobile application and everything appeared to go smoothly—until I tried to launch it. Right after installation the app attempts to talk to the backend and immediately throws a server error. The APK itself installs without complaint; the trouble starts only once the first request is sent. I need someone to dive in, locate the root cause on the server side, and implement a clean fix so the app can connect reliably every time. Access to the server, source code, and crash logs is ready for you as soon as we agree to move forward. Please bring experience with common Android back-end stacks (Node, PHP, Java, or similar) and a methodical debugging approach. Once resolved, I’ll confirm the build installs and runs error-free on multiple ...

I built my site with an AI generator and everything has been smooth until one stubborn page: every image on that page refuses to show. All the files sit right on the same server as the website, yet they still fail to appear in the browser—no broken-link icons, just empty space. I haven’t been able to verify whether the paths are mis-pointed or if something deeper in the PHP is blocking them, so I need a fresh set of eyes. Here’s what I’m after: • Quickly locate the root cause of the missing images on that single page (file-path, permissions, header output, or anything else you uncover). • Apply the fix and confirm the images render correctly across modern browsers. • Walk me through what went wrong and how you fixed it so I can avoid the same s...
Web app built with that I converted into a mobile app using Appilix. The app works but has several issues.

I’m looking for someone who can mainly fix and optimize the mobile app, plus handle a few minor fixes on the Bubble side. Main Issues to Fix (App): Some buttons don’t respond or work inconsistently Navigation can lag or freeze App responsiveness is worse than the website Some mobile UI interactions don’t feel smooth Minor Work (Website / Bubble): Fix a few buttons / workflows that are also buggy on Bubble itself Important: The website mostly works...
I want to craft a classic side-scrolling platformer for a 6502-based console (Atari 7800) and need the entire game engine written from scratch in pure 6502 assembly. Nothing from previous projects will carry over, so every subsystem—graphics, input, physics, scrolling, and sound—has to be engineered fresh and optimised for tight memory constraints. The focus is solely on core engine programming. I’ll supply game design direction (it will be a frog sprite that hops tree to tree using his tongue to achieve a high score, simle arcade styled game), but to start the project I need: • 6502 assembly source code • Build scripts or makefiles that assemble a runnable ROM image • A simple demo level proving horizontal scrolling, sprite animation, collision detec...

I’m running a live WooCommerce store and my checkout is failing whenever a customer selects PayPal. The order never completes, WooCommerce shows a generic “payment failed” notice, and the PayPal logs record an “invalid request” response. Everything else on the site is stable, so this is clearly a payment-gateway specific bug that needs urgent attention. Here’s what I know so far: • WooCommerce, WordPress, and all plugins are up to date. • PayPal is set up with the official WooCommerce PayPal Payments plugin (latest version). • API credentials have been double-checked and re-issued, yet the error persists. I need an experienced WooCommerce developer who can: • Trace the exact cause of the PayPal failure—whether it&rsq...
Our core business platform still runs on Visual FoxPro 9.0 and, while it remains stable, new issues surface whenever data volumes spike or Windows updates roll out. I need an experienced VFP hand to step into the codebase, trace defects, optimise slow queries, and generally keep the application healthy so staff can work uninterrupted. Here’s how I see the engagement unfolding: • Diagnose and repair any runtime errors or data-related glitches we flag. • Streamline heavy reports and long-running SELECTs to improve performance against tables that now exceed several million rows. • Refactor screens or forms where legacy UI logic causes freezes or display problems under newer Windows builds. • Leave the code cleaner than you found it—comment your changes ...
I need a sharp-eyed Flutter / Node.js troubleshooter to pinpoint and fix an intermittent signup failure in my mobile app. The OTP step completes successfully, yet many users (on both iOS and Android) hit a wall when the form tries to create the account. No explicit error is returned to the UI, but the account never appears in the database. Here is what I can share right away: • Front end: Flutter 3.x, using MSG91 for phone-based OTP. • Back end: Node.js (Express) REST API, MongoDB. • Flow: user enters phone → receives OTP → OTP verified → form posts profile details → failure occurs after the POST. What I need from you is a fast, reproducible diagnosis, a clean code fix (whether in Dart, the REST endpoint, or both), and a short hand-off note so my te...
My PHP 8.x application has picked up a fair amount of dead weight—unused files, legacy snippets, and the odd warning that only shows up in the logs. I need a developer who can open the hood, keep what truly matters, and scrap the rest while making sure everything that stays runs flawlessly. Here’s what I’m asking you to do: • Read the entire codebase, identify the core file(s), and strip away anything that isn’t required. • Hunt down every notice, warning, or fatal error and resolve it so the script executes cleanly on PHP 8.x with error reporting turned up. • Where you see obvious performance wins—query consolidation, tighter loops, lighter includes—go ahead and tune them. • I’m not entirely sure which smaller features ...
My OpenCart store is currently unable to complete orders whenever customers choose at checkout. The payment window opens and the customer submits their card details, but the process never reaches the final “order confirmed” stage in OpenCart, so no order is recorded in the back-office and no confirmation email is sent. Other gateways behave normally, so the problem appears isolated to the integration. I need someone who knows OpenCart’s checkout workflow inside out and is comfortable digging into the extension, transaction logs, and any JavaScript or server-side conflicts that might be interrupting the callback. Your goal is simple: identify the failure point, apply the fix, and prove that an order can move cleanly from payment to confirmation every time. Deliverable...

Our in-house desktop application for Linux has started throwing an error that disrupts a critical workflow. I already have the full source code and a reproducible test case; what I now need is a clean, well-documented bug-fix patch that eliminates the issue without introducing regressions.

I have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate. Stability and reliability are my chief concerns; speed is acceptable once the board reconnects. The task is straightforward: go through the existing codebase, spot whatever is undermining the connection logic, and supply clear, working fixes. Serial logs, event callbacks, power-saving modes, and DHCP handling are all fair game—whatever it takes to stop the frequent disconnects. Deliverables • Annotated version of my original source showing every change made • A concise technical note explaining the root cause and the remedy (1–2 pages) • A quick reconnection stress-test script or steps I can replicate to p...

I’m looking for an experienced Windows native developer (C++ / reverse engineering / performance optimization) to analyze and refactor an existing desktop application startup flow. The application currently performs blocking network checks during startup, which significantly slows down launch time and makes it dependent on an external service availability. Goals: Analyze application startup sequence Identify blocking operations (network / license / initialization) Propose and implement a faster startup approach (e.g. async checks, caching last valid state, or local test mode for development) Improve overall startup performance and stability Tech details: Windows desktop application Native executable (C++ / mixed native) Tools used: IDA / Ghidra Requirements: Strong experi...

I need a clean, well-structured Python module that connects directly to the Home Assistant API, handles authentication, and exposes simple functions for reading and updating entity states, firing events, and subscribing to real-time changes. Everything should be wrapped in reusable classes (ideally async-friendly) so I can drop the code into an existing project without major refactoring. While Home Assistant is the immediate focus, I also keep Google API and Gorq API integrations on the roadmap, so designing the code in a way that lets me add further REST endpoints later would be a bonus. Deliverables • Fully commented Python code (Python 3.10+) that authenticates and performs the core CRUD operations against the Home Assistant API. • A short demo script (CLI or Jupyter not...

Hosted on Replit (Autoscale deployment). The Problem: The app works perfectly in development mode, but after deploying to production on Replit, the browser shows a blank/white screen. No visible errors in the browser console (or provide any you do see). Build Process: Vite builds the frontend to dist/public, esbuild bundles the server to dist/index.js. Express serves the static files in production. The build command is npm run build && npm run db:push, and the production run command is node dist/index.js. What I Need: Diagnose why the production build renders a blank screen Fix the issue ...
I have an existing Android APK but no accessible source code. I need the app fully de-compiled, cleaned up, and re-assembled so I can continue development. Once the codebase is restored, I’ll want a few targeted edits—mostly refactoring and minor feature adjustments that we’ll clarify together after you review the decoded project. What I expect from you: • Produce a readable, gradle-based Android Studio project reconstructed from the current APK. • Implement the agreed code changes, then compile and deliver a fresh, working release APK plus signed debug build. • Document every modification so I can pick up future work without hand-holding. You’re free to use jadx, apktool, or any equivalent reverse-engineering toolchain as long as the final pr...

I’m a newly minted Integration Engineer who wants to move beyond theory and get confident inside the Fiorano Integration Tool. To do that, I’m booking a focused, 60-minute video or voice session with someone who has real-world Fiorano experience and knows how to translate that knowledge to a beginner. During our call I’d like to walk through practical integration scenarios, then zoom in on the areas I find toughest—debugging, routing, selectors, XSLT flows, and the overall logic that ties a complete solution together. By the end of the hour I should not only understand what to click but why it matters in production. Key topics I need you to cover clearly: • Common debugging techniques • Routing configurations • Handling errors in flows After ...
I have roughly 30 slot game files built entirely with plain HTML, CSS, and JavaScript—no external libraries or frameworks. When I launch them, certain functions refuse to fire and the console fills with both syntax and runtime errors. Here’s what I’ll provide: • Full source folders for each game • Step-by-step reproduction notes • Detailed browser console logs What I need in return: • Clean, well-commented fixes that eliminate the current syntax and runtime errors • Assurance that every game spins, pays out, and resets exactly as designed • Compatibility when hosted locally (e.g., from a simple HTTP server) and when deployed to a public website • A short report outlining what was broken, what you changed, and any best-pra...

I’m working with a Windows batch (.bat) file that has been heavily obfuscated and is now difficult to read or maintain. I need it fully decoded into clean, human-readable form so I can keep using it with confidence. Once it’s legible, the job continues with performance-focused edits: streamline redundant calls, tighten loops, and generally make the script run faster and leaner without changing its core behaviour. Here’s how I see the flow: 1. Deliver a beautified, well-indented version of the original script, with comments that map sections back to the obfuscated source so nothing is lost. 2. Identify and implement performance optimisations—anything from smarter variable usage to consolidated commands—then supply a revised .bat file. 3. Provide a brief chang...
My SaaS platform is currently written in PHP with no framework support. As the codebase grows, small bugs and performance hiccups are becoming harder to track, so I want the entire application ported to CodeIgniter.

My ASP .NET website loads fine until the moment a user logs in—right after pressing the Login button an error message pops up and the page stops there. I can capture and share a screenshot of the exact message, but I don’t have the text copied out. Nothing else needs to be clicked for the issue to appear; it happens instantly after authentication. I’m looking for someone willing to troubleshoot this one-off problem pro bono. You’ll have temporary access to the project files or a zipped copy (C#, .NET Framework, SQL Server back-end) so you can replicate and patch the fault. Once you identify the cause and supply the fix—whether it’s a tweak, an authentication middleware adjustment, or a code-behind patch—I’ll implement it on the live serve...
During the next 6–9 months we’ll be working with a Chinese OEM that is adding several key capabilities to its new 4G/5G router line: higher data-throughput paths, richer network-management options, and extra data interfaces such as serial ports and general-purpose I/O. All new code must interoperate with the OEM’s own proprietary protocols, so every build needs to be exercised against their closed, in-house stacks. Our immediate need is rigorous quality-assurance and debugging support throughout the development cycle. Your job is to design and run repeatable tests and make sure we meet customer's objective, and feed concise feedback and bug reports to the factory team. Expect iterative rounds of validation on both bench setups and pre-production hardware. Once the ...
I have an existing scheduling code-base written entirely in JavaScript. At the moment its only fully working feature is the user-notification system, yet the app is already showing performance bottlenecks that slow page loads and make real-time updates feel sluggish. What I need first is a thorough cleanup and refactor that targets performance: untangle duplicated logic, remove dead code, split oversized functions, and trim the bundle so it ships fast. While you work, please leave the code more readable and well-documented so future contributors can follow along without guesswork. Your primary deliverable will be a redeployed build that runs noticeably faster on both desktop and mobile. If you spot bugs on the way, squash them—clean tests must pass before hand-over. After that,...
I'd like to create a schematic and PCB layout that I can use to print from a photo I have. The layout is based on an ATmega and an ESP32, along with a servo connected to the ATmega. I'd like a guide on how to create a schematic file that I can modify and use in the future, not just the photos I have.
The current production build of my app is intermittently crashing, and I need a clean, targeted code update to eliminate these functionality-related bugs without introducing new issues. The crashes appear after recent OS updates and seem tied to memory handling inside two core screens; logs point to null pointer exceptions in the data-binding layer. You’ll receive: • Full Git repository access (Android, Kotlin + a small legacy Java module) • Current crash logs from Firebase Crashlytics and Logcat • A short video that reproduces the issue on two devices What I need from you: 1. Diagnose the root cause of the crashes. 2. Refactor or patch the affected classes so the app runs reliably across Android 8-14. 3. Commit code in a separate branch with clear co...
