Job-application automation platform (hh.ru), team of 6 - Built a multi-tenant auto-apply system on Python (FastAPI, Django, Playwright) with fully isolated per-user sessions, handling ~200 applications/day for ~100 users. - Reverse-engineered undocumented hh.ru endpoints via traffic interception and implemented browser-free authentication and vacancy search on top of them. - Implemented CAPTCHA solving and block-evasion layers (proxy rotation, fingerprinting, session management); built proxy traffic monitoring to track cost and failure rates. - Designed deduplication and retry logic (Redis-backed queues, idempotent apply flow) to prevent duplicate applications and recover from transient failures. - Deployed on Docker/Kubernetes with CI/CD pipelines; covered core flows with automated tests. - Built Vue.js frontend components for user-facing configuration and status.
