I learned to build software by learning how it breaks

I'm a Full-Stack Engineer at Ultralytics, where I help build the platform for training and deploying YOLO computer vision models. Over 6 years, I've designed and shipped frontend, backend and cloud infrastructure end to end.

I started in Quality Assurance, building automation frameworks with Selenium, Playwright and PyTest. That taught me to think in edge cases and build systems that don't fall over, and I still bring that to every product.

Today I work across the stack: Next.js, React and Tailwind up front, FastAPI and Node.js behind, with a specialty in bringing computer vision into production apps.

Outside work I ship side projects like Pashudhan, an AI classifier for 75 Indian livestock breeds built for Smart India Hackathon, and explain tech to 87K+ subscribers on TechDecode.
