Hire Shailesh Chaudhari

Software Engineer at ContextQA, working on the backend of our core QA-automation product (test execution engine, VNC streaming, Playwright / WebdriverIO / LambdaTest orchestration). First 2-3 months at ContextQA I shipped 2 Chrome extensions (Vibe Testing, AxeTos). Previously ~2 years at EsparkBiz shipping full-stack client projects end-to-end. Side projects explore distributed systems (Redlock, Socket.io Redis adapter), AI pipelines (Gemini function-calling + OCR), and webhook idempotency patterns. TypeScript everywhere, correctness first.

What I work on

Full-stack web apps — Next.js + Node.js / NestJS, Prisma, PostgreSQL
Chrome extensions — content scripts, service workers, DevTools panels, backend APIs
Real-time systems — Socket.io with Redis adapter for horizontal scaling, distributed locks
AI integrations — Gemini AI, pgvector semantic search, OCR pipelines, webhook deduplication
Performance — Core Web Vitals, bundle analysis, ISR vs edge caching, AVIF optimization
Database design — PostgreSQL (RBAC, RLS), MongoDB, Prisma, Supabase

How I work

I prefer small, shippable iterations over big-bang deliveries. I share working code early, flag blockers quickly, and write tests for anything that needs to stay working. I'm remote-first and async-friendly.
