จาก 37,287 รีวิว ลูกค้าให้คะแนน Debugging Experts 4.9 จาก 5 ดาวI’m developing a Graphical User Interface on an STM32F469 Discovery board and want it to look and feel like the demo in this video: My toolchain is TouchGFX together with STM32CubeMX and STM32CubeIDE, and I’m hitting the ceiling of what the tutorials on the web cover. Here’s what I need: • A hands-on example project that runs on the F469 and shows off complex, fluid animations, polished screen navigation, and a few custom-looking widgets so I can study and extend the code. • Guidance while we build it so I understand why each performance tweak or memory setting matters. • An honest assessment of whether the F469 can truly handle this level of visual richness; if not, point me to the exact board or MCU family that can, plus any advanced courses, bo...
I have a small Todo app built with React hooks that keeps everything in the browser via localStorage—no database or external state library, just useState throughout. After I added simple filter tabs (All / Active / Completed) by following a YouTube tutorial, three issues appeared: 1. A freshly added todo often disappears after a full page refresh. 2. Editing one item sometimes changes a different item instead. 3. Hitting “Clear completed” while on the Active tab deletes tasks that are still active. In your bid tell me what you think causes problem number 1.

I already have a fully approved WordPress-based prototype with a completely custom design, packed with several bespoke animations and micro-interactions. What I need now is a production-ready static build that mirrors that prototype pixel for pixel and motion for motion, while performing flawlessly on desktop, tablet and mobile. Here is the scope you will take over: • Replicate every layout, navigation flow, animation and interaction shown in the prototype, translating the current WordPress mock-up into lean, well-structured HTML, CSS and Vanilla JavaScript (or similarly lightweight tech of your choice). • Embed Meetergo calendar booking on the pages indicated in the prototype, keeping styling fully consistent. • Deliver clean, well-commented, maintainable code that is...
My React front-end is fairly stable, yet the Node.js / Express REST layer that feeds it still trips over itself. Some endpoints lag, others throw inconsistent errors, and the authentication flow occasionally lets requests slip through untouched. Here is what I need from you: • Profile every REST route, identify the hotspots, and bring average response times back to an acceptable range. • Add (or tighten) centralized error-handling so callers always receive a predictable JSON structure. • Review the current authentication / authorization middleware, patch any logic holes, and make sure protected routes really stay protected. • Clean up any code smells you encounter along the way so future maintenance is easier. I exercise the API with Postman at the moment, b...
I need an experienced developer who feels at home working with both .NET and Angular to help me track down and eliminate a series of stubborn errors inside an existing SAP-integrated application. The immediate goal is straightforward: identify the root causes, patch the code, and confirm that the fixes perform flawlessly in our test and production landscapes. The stack you will step into is built on a .NET back-end that communicates with SAP through standard connectors, with an Angular front-end handling the user interface. Because the pain point is debugging, I am looking for someone who can read unfamiliar code quickly, reproduce the issues, and apply clean, well-documented fixes that follow best practices for both C# and TypeScript. Acceptance criteria • Each reported error is ...

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. Pages occasionally break, certain features behave unpredictably, and error messages are starting to appear in the browser console as well as the server logs. The exact layer—frontend, backend, or database—hasn’t been pinpointed yet, so I need a developer who can methodically debug across the full stack, isolate root causes, and deliver clean, tested fixes. 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.
