About Me

I'm a Software Engineer from Patan, Gujarat, currently based in Ahmedabad. At ContextQA I work on the backend of our core QA-automation product — test execution engine, VNC streaming, and browser-automation orchestration (Playwright / WebdriverIO / LambdaTest). The first 2-3 months I shipped 2 Chrome extensions (Vibe Testing, AxeTos) before moving to the core product. Before ContextQA, I spent ~2 years at eSparkBiz building EdTech, e-commerce, and corporate training platforms end-to-end. On the side I explore distributed systems (Redlock, Socket.io Redis adapter, Prometheus metrics), AI pipelines (Gemini function-calling, OCR), and webhook idempotency patterns. I reach for correctness over convenience.

Core platform backend: Node.js + Express services orchestrating test runs across Playwright / WebdriverIO / LambdaTest, VNC streaming for live browser-session debugging, and the APIs that drive run history, assertions, and artifacts.
