Hi, I'm Shailesh Chaudhari
Full-stack engineer with a backend focus
~2.5 years in the industry. Currently at ContextQA working on the backend of our core QA-automation product — test execution engine, VNC streaming, and multi-cloud browser orchestration across Playwright / WebdriverIO / LambdaTest. Comfortable across the stack from my EsparkBiz client-project days, but I go deep on backend systems: distributed locks (Redlock), real-time pub/sub (Socket.io + Redis adapter), webhook idempotency (SETNX), AI pipelines (Gemini function-calling). Targeting backend, platform, or developer-tooling roles.

Outside of my day job, these are the small-to-medium projects I work on to explore specific backend patterns end-to-end.
