About me

I’m Sachin, a QA Automation Engineer with 3 years of combined professional and freelance experience testing web and mobile applications across Android, iOS, and cross-browser environments. I build automation frameworks with Playwright, Selenium, and Appium, backed by Pytest and TestNG, and handle API testing with Postman and REST Assured.

I focus on identifying defects early, reducing regression cycles, and ensuring reliable end-to-end user experiences. I enjoy working in collaborative Agile teams and am driven by continuous learning and process improvement to help teams ship stable, high-quality products.

OKAS — Smart Home, Shipped to Production

OKAS is where I do my most demanding work: a live IoT home-automation product, not a one-off client site. Owning QA across 3 web platforms and native Android/iOS apps means testing real-time device pairing, scene sync, and state consistency across 5 product surfaces at once — the kind of production-grade, product-based ownership that's a different game from testing a single website end to end.
