I have a production Flutter web app that needs a solid pass of debugging and refinement. Three categories of problems are currently blocking smooth usage: • UI/UX issues – mis-aligned elements, inconsistent theming and interactions that don’t feel native in the browser. • Performance issues – noticeable jank when the first dashboard loads, slow transitions between routes and heavy CPU usage on form pages. • Functional errors – actions occasionally fail, state is sometimes lost after navigation and a few buttons do nothing on click. The pain points show up most in the login & registration flow, the main navigation/menu drawer, several forms and, overall, the app’s general runtime performance. What I need from you 1. ...

My drone’s flight control software is showing serious stability problems—unexpected pitch and roll changes that make the aircraft drift even in calm conditions. I need an engineer or developer who can dive into the existing flight-control codebase, pinpoint what is causing the instability, and implement a solid, tested fix. The job starts with a code review to isolate the root cause in the flight-control module, followed by refactoring or patching the affected algorithms (PID tuning, sensor fusion logic, or any timing issues you uncover). Once the fix is in place, I’ll need a compiled firmware image plus clear documentation of the changes so I can reproduce the build and flash future units. Acceptance criteria • Drone must hover and track waypoints without unexpe...

Mi controlador a nivel kernel para Windows ya está prácticamente terminado, pero necesito que alguien lo compile de forma limpia en Visual Studio 2022 y lo deje listo para comercializar. El trabajo consiste en: • Abrir la solución actual en Visual Studio 2022, resolver cualquier conflicto de versión y generar el binario firmado. • Incorporar las tablas tipo “Kernel- Driver” que me faltan; están definidas en el código pero aún no se crean correctamente dentro del propio driver. • Ajustar el controlador para garantizar compatibilidad con el nuevo software al que debe dar soporte (corre en Windows 10/11). • Verificar que no queden advertencias de WDK y que pase las pruebas de integridad de Microsoft Driver Veri...

I have developed a Windows data recovery application (RecoverPro) that works correctly for most file types such as images, videos, and documents. However, there is a specific issue with executable (.exe) files: During recovery of any .exe file, an error popup appears Recovered .exe files are either not usable or fail to restore properly Detection may work, but recovery process fails Important: Other file extensions are recovered perfectly without any issues The problem is isolated only to .exe file recovery To properly diagnose this, the application needs to be tested directly. Freelancers are requested to download and test the app. Note: The app is currently paid and can't be free immediately (due to Microsoft Store policies), but any cost incurred will be fully compensated (re...

I have two production Laravel applications running smoothly on PHP 7.5, and it is time to move them both to PHP 8.2. Each project includes several custom-built modules, so the task goes well beyond a simple composer update. Your mission is to audit the current codebases, refactor anything that breaks under PHP 8.2 (type changes, deprecated functions, strict typing issues, etc.), update third-party packages as needed, and hand the projects back fully tested and ready for deployment. Key points for context • Framework: Laravel (both projects) • Custom features: yes—multiple bespoke modules that must keep working exactly as they do now. Deliverables 1. Two upgraded repositories running on PHP 8.2 with no deprecated warnings or breaking errors. 2. Updated / and...

Our online résumé builder is throwing small errors that all trace back to a mis-configured .env file. Because of this, users relying on the standard email-and-password flow can’t log in, and once they do manage to get past that hurdle, the template selector occasionally fails to load the chosen layout. Also we need to update the job API to the right API so users are able to select the right job and it redirects to the right job... Here’s what I need from you: • Audit the current environment variables, spot the mismatches, and put them in the correct format for both local and production builds. • Restore reliable email-and-password authentication so that login failures disappear. • Track down and fix the template-selection glitch (it currently ...

Hi, I have a Shopify store and I am facing a serious issue with high abandoned carts and checkouts. After installing a session recording app (Propel Replays & Heatmaps), I can clearly see that many customers are getting JavaScript errors during cart and checkout. Customers are: Adding products to cart Clicking checkout Even reaching payment (PayPal) But then something breaks and they leave without completing the purchase. This is happening across multiple sessions and devices (especially mobile), so it is not a user issue it is a website problem. What I need I need an experienced Shopify developer to: Identify the JavaScript errors on my website Check for app conflicts (currency converter, popups, tracking scripts, etc.) Review theme (Debut) for any issues Test full checkout flow (car...

My current GA4 + GTM implementation is producing unreliable numbers and I need a specialist to go through the entire stack, locate the leaks, and leave me with clean, fully-verified data. Scope of work • Audit the existing GA4 and Google Tag Manager containers, then cross-check every tag, trigger and variable against the measurement plan. • Identify why I’m seeing data discrepancies, missing conversions and incorrect event firing across GA4, Google Ads and the Meta Pixel. • Fix each issue, optimise the tagging strategy and, where useful, implement server-side or CAPI improvements for Meta. • Re-confirm that Google Ads conversion actions are mapped correctly to GA4 events, with consistent attribution. • Validate everything in real time with Tag Assi...

I’m sitting on a backlog of forty separate bugs that all fall under the same umbrella: existing features aren’t behaving the way they’re supposed to. The core of the task is straightforward—identify what makes each feature fail, patch it, and prove it works without introducing regressions. You will get full access to the repository and a brief description of each mis-behaving feature. I expect clean, well-documented commits for every fix so I can trace what changed and why. Once all forty are addressed, ship a single pull request and a short changelog. Acceptance criteria: • All forty issues closed in the tracker • No new warnings or errors in the console or logs • Regression test suite passes completely If you have a knack for hunting do...

I need a small, purpose-built payload that I can inject into my own desktop application to probe for buffer-overflow weaknesses. Off-the-shelf fuzzers such as libFuzzer, AFL, or similar suites are off-limits for this exercise; the whole point is to rely on clean, hand-written C code and low-level debugging techniques. You’ll be working on a recent Linux distro where I can give you SSH access to a hardened test VM. Expect to spend most of your time inside vim, gcc, and gdb (remote debugging with gdbserver is fine if you prefer). The program you’ll attack is closed-source to everyone except you and me, so everything must stay in userspace—no kernel tricks, no external libraries that do the heavy lifting. What I’m after • A minimal C source file (or small set ...

My pathway already performs smoothly in text, but the moment we switch to voice a few critical problems appear. The system starts throwing spelling errors, misunderstands certain words, and the overall exchange stops sounding human-like. I need these pain points fixed so the voice experience feels just as polished as the text one. What I want improved • Spelling accuracy and consistent transcription • Better word understanding, especially in everyday speech • A natural conversation flow that doesn’t break when the user pauses or re-phrases Primary use-cases The pathway has to handle casual conversations and customer service inquiries without stumbling. Think quick back-and-forth chats where clarity and tone matter. Acceptance criteria • A/B voice tes...

PROJECT DESCRIPTION Package E – Embedded Firmware Development Project: Box Capsule 1. PROJECT OVERVIEW Box Capsule is a vehicle-mounted hardware device designed to physically restrict access to a mobile phone while driving. The system operates as a standalone embedded device. Its purpose is to reduce driver distraction by controlling physical access to the phone based on real-world conditions such as motion and user interaction. This is not an app-based solution. All critical functionality must be executed locally on the device. 2. SYSTEM OBJECTIVE The firmware must control a locking mechanism that: * allows the user to insert a phone * detects lid status (open/closed) * detects motion or driving condition * locks the phone when required * prevents access while driving * allow...

I have a Windows-only desktop program for personal use. The original supplier is no longer available, and every launch now stops at a login screen that asks for an authorization code I can’t retrieve. I still have lawful access to the software and simply need to keep using it on my own PC. What I need • Analyse the executable and locate the routine that validates or fetches the authorization code. • Produce either a patched binary or a small loader that cleanly bypasses that check so the software starts normally. • Preserve all existing features and stability; nothing else in the workflow should break. • Provide a short, step-by-step note on how the modification was done so I can replicate it after system reinstalls. Helpful skills Experience with Windows ...

My WordPress site needs a thorough clean-up so it loads fast and runs smoothly. Google PageSpeed Insights shows bottlenecks coming from the database, the codebase, and the active theme, so I want each of those layers optimised without breaking existing functionality. Beyond speed, a handful of small but visible issues have crept in: the logo disappears on some pages, a few images refuse to load, and the footer layout has slipped out of alignment. I’d like those tidied up while you are already in the templates. Two marketing plugins—Icegram and WP Loyalty—are currently misbehaving. Both need to be debugged, updated if necessary, and returned to full working order. Intermittent 404, 503 and 505 errors are also showing up, and Cloudflare occasionally throws a network erro...

The PayPal-enabled order forms built with Ninja Forms have suddenly stopped appearing. When a visitor clicks the link on the page, nothing loads—no error, no redirect, just an unresponsive link. I recently renewed the Ninja Forms license for another 12 months, so the plugin is up to date and active, yet the forms remain inaccessible. Your task is to trace and resolve whatever is preventing the form from displaying, whether it lives in the form settings, the shortcode/HTML link, WordPress updates, or the PayPal add-on itself. Once complete, users should once again be able to open the form, fill it out, and proceed through PayPal without interruption. Acceptance criteria • The form link reliably loads the correct Ninja Form on every device/browser we test. Test using Paypal ...

My site, , is still sitting in staging because of a handful of stubborn functionality problems. The homepage in particular throws intermittent errors and several navigation links lead to dead ends, so the user journey breaks right at the start. I need someone to step in, trace the root cause of those crashes, repair the broken or mis-routed links, and make sure every critical path loads without hiccups. Once the fixes are in place I want the site moved out of maintenance mode and made fully live, with a quick sanity-check across common browsers and mobile resolutions to be sure nothing else surfaces. Please document the changes you make so future updates remain straightforward. Deliverables • Debug and eliminate homepage crashes/errors • Repair all broken or misdirected lin...

I need a sharp front-end developer to jump into the existing React codebase behind and give our Map View the polish it deserves. Your mission is clear: fix the lingering issues, tidy up the layout, and make every pixel responsive. The priorities are straightforward—resolve the current bugs, upgrade the interface, and refine the map markers and overlays so they look crisp and behave consistently on any screen size. The stack is React (hooks and functional components) with CSS-in-JS. You’ll be working inside the current structure, not rewriting it from scratch, and pushing clean commits to our Git repo. Deliverables • Updated MapView components with all issues fixed and layout improvements merged • Responsive styling that scales smoothly across common breakpoints...

Ideal candidate should be highly reliable, communicative, and confident working with Shopify themes, WooCommerce, and custom template logic. Detailed b...

I need a Laravel specialist to jump in and solve two blocking problems that appeared right after I moved some folders and tweaked the server configuration. First, the admin panel routes for /login and /register suddenly return a 404. They worked before the move, so I’m guessing something went wrong with the route bindings, entries, or perhaps the middleware stack. Second, every image that lives in storage/ no longer renders on the site. The paths look intact, yet the browser can’t find the files. A fresh storage:link or a path correction in config/ may be all that’s needed, but I’d like you to trace it properly rather than apply quick guesses. What I expect from you • Diagnose and restore the admin authentication routes so the forms load and submit succes...

Please ensure the final build passes a quick functional test on Windows 10/11, with no antivirus flags or instability introduced. If you have solid ex...

I need a clean, well-commented ladder program built in Connected Components Workbench for an Allen-Bradley Micro 850. The code will control a short conveyor section that feeds a product flipper and then sends the item out the opposite end. The hardware is already defined: we’ll be using photoelectric sensors for all product detection, and the PLC must honour both an Emergency Stop line and the required safety interlocks. I’ll supply the full I/O list, sequence of operations, and any timing details the moment we start. What I expect from you • A CCW project file containing the ladder logic, organised and labelled so future fault-finding is straightforward • Comments on every rung that explain the intent, tied back to the step numbers in my functional description ...

I’ve already built the core of my site with lovable and Supabase and I have both the file and the React-based layout where the report should live. What’s missing is the actual CV Audit report component and the wiring that lets it flow smoothly through the existing pages. Here’s the scope: • Code the CV Audit report module, pulling data from Supabase as needed and rendering it in the designated layout section. • Hook the component into the current routing so it appears exactly where the placeholder now sits. • Walk the full user journey end-to-end, fixing any TypeScript, state-handling, or API hiccups you spot along the way. • Confirm the final build works locally and in production, ready for me to push live. While the platform may eventually ...

I already own a tweaked APK of AirAttack 1941 that links energy-recovery to gameplay speed, but it caps out too soon and crashes after extended play. I need you to rebuild the mod so I can push the action far faster—ideally up to 8× or beyond—while keeping everything rock-solid. Here is exactly what I’m after: • Deliver a new APK/APKS (no source code available) where a single in-game slider lets me select any speed from the normal 1× all the way to the top limit you can safely reach (8× minimum). • Energy-recovery must keep scaling with speed just as in my current build. • The game must remain smooth: no random crashes, freezes, or stutters even during long sessions or heavy effects. • Gameplay, graphics, and progression must ...

I have a PHP script, the Food Delivery from PHPJabbers, the Developer’s License, that is currently running in PHP 7.4 but I need to move it to a new server that runs 8.4. I am able to make the backup of the DB (MySQL/MariaDB) from the existing server as well as to upload the DB to the new server. And I see that everything is uploaded, customer list, food products, categories, settings, everything is uploaded, but the problem is when I login to the admin side, there are issues, issues of incompatibility, as 2 buttons on the navigation menu do not work, and not all links work. The navigation menu for instance, when clicking on the Payments button to expand the sub-menu, the expandable navigation menu fails to load, and the payment options as buttons/icons, do not appear. I tried to fix...

My current AnyLogic simulation is fully built and already addresses data flow and data-leakage scenarios, yet a handful of functions are misbehaving and a few code fragments are still throwing intermittent errors. I want to concentrate first on improving these functions, with special attention on the user-interface interactions that trigger or display key data-flow events. Here is what I need from you: • Debug the existing Java code inside the model, remove the residual errors, and streamline the logic behind the UI-driven blocks. • Refactor or redesign any function that currently hampers smooth data flow or that could accidentally mask leakage signals. • Once the fixes are in place, walk through the validation steps I have already carried out, confirming that my test ...
