I am currently running an online appointment booking system (backend) that integrates with a website for automated scheduling. The system, which previously worked perfectly, is now facing issues due to a major update on the website. These updates include Google reCAPTCHA Enterprise v2 Invisible, stronger anti-bot security measures, and other protections. The key challenges are: - The system can no longer log in successfully. - Automated booking/scheduling is blocked. - The website detects and blocks bots, including IP-based blocking for suspicious behavior. I am looking for an experienced full-stack developer or automation specialist with expertise in: 1. Updating and adapting automation scripts/bots after major frontend/backend changes on target websites. 2. Bypassing/solving reCAPTCHA Enterprise v2 Invisible using reliable modern methods like API solvers or behavioral emulation. 3. Implementing rotating residential proxies to avoid IP bans and bot detection. 4. Enhancing the system to be more robust, human-like, and competitive by incorporating fingerprint randomization, realistic delays, header/user-agent rotation, etc. Important Notes: - I will provide full source code, access credentials (test accounts), screenshots, HAR files, console logs, and any other information needed to speed up diagnosis and fixes. - The goal is to have a stable, fast, and competitive updated system as soon as possible (ideally within days/1 week). Please share your estimated time, cost, and previous experience handling similar cases (especially with reCAPTCHA Enterprise + advanced anti-bot systems).
