I’ll diagnose your existing scraper, align it to your stealth engine + Playwright/Puppeteer setup, fix browser-level issues like new windows, redirects, dynamic content, and harden stealth so it runs undetected with clean, commented, tested code. For screening: I only work on publicly available data or targets where you confirm explicit authorization to scrape, and I’ll review your engine + stealth module first to ensure compliance and reliable integration before writing a fix.

@nemanjam61

Hello, I have extensive experience fixing and maintaining existing scraping systems, including Playwright, Selenium, session management, dynamic content handling, and integrating scrapers into established architectures. I'll review your engine and stealth module, diagnose the scraper's failure points, align it with your framework, and deliver a clean, tested solution that handles redirects, browser challenges, and reliability issues. I have a question, is the scraper currently built with the same framework as your core engine (Playwright/Selenium), or does it need to be migrated during the integration?

@cuyodigital

Let me know your answers. I can start right away. Ricardo

@TanvirProttoy

Hello, A broken scraper inside an existing stealth engine usually points to integration mismatches rather than scraping logic itself, especially around session handling, browser context isolation, or fingerprint consistency. The fact you already have a structured engine is actually a strong advantage because the fix is about alignment, not rebuilding. In a recent scraping system built with Playwright and rotating stealth contexts, I resolved persistent blocking issues by tightening fingerprint consistency and fixing navigation flow across redirects and new tab events, which restored stable extraction under dynamic pages. One key insight for your case is to validate whether the scraper is leaking contexts between requests or bypassing parts of your stealth layer during redirects, which often breaks detection resistance even when the core scraper looks correct. If you share the current failing module and expected flow, I can pinpoint the breakpoints and align it cleanly with your engine so it runs reliably and predictably. Best regards

@coretus

Your scraper is broken, but the real value here is getting it aligned with your existing engine and stealth flow without rewriting everything. I can diagnose the failure points, fix browser handling issues, and make the scraper fit your current architecture cleanly. I work with JavaScript/Python web development and can extend an existing codebase, handle redirects, new windows, dynamic pages, and session flow, then return tested, commented code. What I’ll do: 1. Review your engine and stealth module 2. Trace and fix the broken scraper path 3. Align output to your required format 4. Test the flow end-to-end and harden reliability I’m keeping the bid competitive because the scope is focused and you already have the core engine in place. If you share the source and target behavior, I can start immediately and deliver fast.

@fahad508

Hello, Scraping systems usually break not because of basic selector issues, but due to mismatches between browser automation flow, session handling, and stealth configuration—especially when engines evolve independently of the scraper layer. I will audit your existing scraping engine end-to-end, isolate failure points (navigation, DOM timing, fingerprinting, session state), and refactor the scraper so it cleanly integrates with your stealth layer while maintaining stable extraction under dynamic and protected environments. Experience building and fixing Playwright/Selenium-based scraping systems, stealth browser automation, session management, and large-scale data extraction pipelines within existing architectures. 1. What exactly is the current failure mode—blocked requests, empty DOM, session drops, or inconsistent navigation/redirect loops? 2. Is your stealth layer based on Playwright stealth plugins, custom fingerprint spoofing, or a proxy rotation system (or a combination of these)? 3. Does the scraper need to scale to high-volume concurrent runs, or is the priority stability and correctness of a single optimized extraction flow first? Best regards, Fahad

@talkwaqar

Your scraper is broken and needs to fit the engine and stealth config you already built, not a rewrite. The parts that usually break a working setup are exactly the ones you flagged: new windows, redirects, and dynamic content that the stealth layer wasn't tuned for. I'd start day one inside your source code and stealth module, reproducing the failure before touching anything. How I'd approach the fix: 1. Trace every failure point against your engine's architecture and log where detection or blocking actually triggers. 2. Patch the browser-level handling (popups, redirects, dynamic loads) and align session management with how your engine expects state. 3. Harden fingerprinting and timing so runs stay reliable, then deliver tested, commented code that matches your output format. I work mostly in extending existing Node.js codebases rather than greenfield builds, so dropping into your engine and matching its conventions is the part I'm comfortable with. Done = the scraper runs end to end against the target without being blocked, output matches your expected format. $22, 7 days. Should I scope day one as a diagnostic report first, or go straight into the fix once I have the source? Waqar
