My existing site is built with plain PHP and standard HTML templates, and a few lingering bugs are holding it back from running smoothly. I need an experienced developer to dive into the current codebase, track down the issues, and deliver clean, well-commented fixes that don’t break any of the working pages. You will be working only on functionality—no design or content changes—so your focus is on debugging, refactoring where necessary, and ensuring page loads and actions perform reliably afterward. Once the patches are in place I’ll test them on staging, and we’ll wrap up with a brief hand-over explaining what was changed and why. If you’re comfortable troubleshooting legacy PHP and tightening up HTML markup when it causes functional glitches, I&rsquo...
Python/Playwright Automation Debugging – Turnstile & 2Captcha Integration Fix Project Description: I have an existing Python script that uses Playwright (Chromium) to automate form interactions on a public web portal. The script is designed to intercept Cloudflare Turnstile challenge parameters and pass them to the 2Captcha API for token retrieval. However, the current implementation has a critical bug: The Problem: The Turnstile challenge is rendered inside an isolated cross-origin <iframe>. My script currently executes () on the top-level main frame to read the captured parameters (sitekey, action, data, pagedata). Because of this, it returns None values instead of the actual Turnstile initialization data. What I need fixed: 1. Correctly locate the Turnstile iframe...
I’m experiencing persistent issues in my web application that need to be tracked down and eliminated.

Scope of work • Reproduce the reported errors and identify their source in the codebase. • Implement corrective changes without introducing new regressions. • Document each fix clearly so future maintenance is straightforward. • Provide a brief hand-over summary outlining what was wrong,...

Portfolio Project: The Android Crash & Recovery Lab Instead of just saying you can fix crashes, build a portfolio case study where you deliberately simulate an Android system failure and document the precise engineering steps to fix it. This proves your technical expertise to potential clients. Phase 1: Diagnosing an App-Level System Crash Clients frequently face issues where their app crashes the entire Android system UI or memory management. The Task: Create a basic Android application that intentionally triggers an OutOfMemoryError or a main-thread deadlock (ANR - Application Not Responding) by loading too many high-res bitmaps into memory at once. The Fix: Connect the device to your computer via ADB (Android Debug Bridge). Use Android Studio Profiler to capture the memory leak. Use...

My React Native app is built and pushed to TestFlight, yet every attempt to submit a new build stalls because of two blocking problems: • App crashes • Build errors I already have detailed Xcode and Metro logs ready to share, so you can dive straight into debugging. Your job is to trace the root causes, patch the code or configuration, and produce a clean archive that sails through TestFlight and on to App Store review. You’ll need solid experience with React Native, Xcode, App Store Connect, provisioning profiles, certificates, and Apple’s review guidelines. Once the build is stable, I’d like a quick rundown of the changes you made so I can keep future releases smooth.

I have a 16-channel relay board that must be driven by an Arduino. Each of the sixteen micro-switch inputs will correspond to one—and only one—relay output. When a switch is pressed the matching relay should energise for a fixed pulse of 2-3 seconds, then drop out automatically; there is no need for the user to alter that timing. Here is what I need from you: • Clean, well-commented Arduino sketch that reads the 16 discrete inputs, debounces the switches, and fires the appropriate relay for the required duration. • Pin-mapping and a simple wiring diagram so I can connect everything without guesswork (I will be using a common 16-relay module that accepts active-LOW signals, but please keep the code flexible enough to invert logic if needed). • Guidance on a...

My VBA-driven workbook suddenly throws an error on Windows 11 with Office 2019. I need someone who can jump in right away, locate the glitch, and patch it within the next couple of hours. I will send the workbook and a brief note on the steps that trigger the failure. Once you reproduce the problem, please clean up the code, make it robust for this environment, and send the corrected file back along with a short summary of what you changed and why. Deliverables • Repaired Excel file with fully functioning macro • One-paragraph changelog outlining the fix If you are confident with VBA in Office 2019 and can start immediately, this should be an easy win for you and a quick resolution for me.
My single-product page suddenly looks scrambled—elements overlap, fonts jump in size, and the spacing that used to keep things tidy is gone. The core site runs on WordPress with WooCommerce, and the only urgent task is to bring that layout back to its clean, responsive state. Here’s what I need you to do: • Inspect the current product-page template, trace the exact source of the broken layout (CSS conflicts, stray divs, outdated template overrides, or plugin/theme clashes). • Apply clean fixes—preferably in a child theme or custom CSS/JS—so the header, gallery, description, price, and Add-to-Cart section snap back into proper alignment on both desktop and mobile. • Verify the solution across the latest versions of Chrome, Firefox, Safari, and E...
