Python Developer for IVAC Portal

I am looking for an experienced Python developer to take existing automation scripts and compile them into a fully operational, production-ready bot. The target is a highly protected portal (IVAC), and the script relies heavily on anti-bot bypasses, concurrency, and high-speed execution layers. What you need to do (Scope of Work): • Integration & Architecture Refinement: Cleanly integrate these 14 separate structural modules into a single cohesive, multi-threaded pipeline. • Bug Fixing: Double-check the exact mapping boundaries between the browser-level state extraction and the raw HTTP engine injection. Correct any potential memory leaks or runtime exception holes. • Proxy and VPS Tuning: Ensure the script interfaces correctly with my Bangladeshi SOCKS5 / Mobile Rotating 4G/5G proxy configurations and doesn't leak WebRTC/DNS parameters. • Testing: Run end-to-end simulation tests to confirm the global lock holds perfectly when one thread catches the gateway while the other 9 pause elegantly. Required Tech Stack: • Expert-level Python (Asynchronous Programming, asyncio, Threading). • Deep understanding of Playwright / Playwright-Stealth. • Experience with curl_cffi or advanced HTTP/2 TLS fingerprinting evasion techniques (Akamai/Cloudflare/WAF bypasses). • Familiarity with third-party APIs (2Captcha, Telegram Bots). • Networking tuning experience (Proxifier, Mobile Rotating Proxies, DNS leak prevention).
