Project Overview We need an experienced automation developer to build a resilient, 24/7 background slot-monitoring service. The target portal releases appointment slots intermittently and has aggressive rate-limiting + anti-bot protections. Goal: Create a Slot detection system that: Bypasses IP bans Detects new slots at the API level (no heavy browser reloading) Sends instant alerts the moment a slot becomes available Key Deliverables Endpoint Extraction – Reverse-engineer network requests (XHR/JSON) to monitor slots directly via API TLS / Fingerprint Emulation – Use curl_cffi or proper TLS impersonation to avoid WAF detection Rotating Proxy Integration – Multi-provider residential proxy pool with smart sticky session handling Alerting Pipeline – Instant push notifications (Telegram bot / webhook) triggered strictly on state change Required Skills Strong experience bypassing Cloudflare (Turnstile / Under Attack mode), Akamai, or DataDome Adaptive polling with jitter, exponential backoff, and proper handling of 429/403 errors Ability to write lightweight, standalone Python (or Go) scripts that can run 24/7 on a basic Linux VPS Clean, modular code with config files for proxies, headers, and secrets Technical Evaluation Criteria Area,Expected Approach,Disqualification Red Flag Polling Strategy,Background REST/WebSocket + state difference,Selenium/Puppeteer refreshing every 2 seconds Rate-Limit Avoidance,Residential rotating proxies + jitter + backoff,Hardcoded delays / single IP / no 429 handling Fingerprint Handling,TLS JA3/JA4 spoofing + consistent headers,Default Python requests library AreaExpected ApproachDisqualification Red FlagPolling StrategyBackground REST/WebSocket + state differenceSelenium/Puppeteer refreshing every 2 secondsRate-Limit AvoidanceResidential rotating proxies + jitter + backoffHardcoded delays / single IP / no 429 handlingFingerprint HandlingTLS JA3/JA4 spoofing + consistent headersDefault Python requests library
