How I work

Frontend craft with product thinking.

I translate product requirements and backend capabilities into accessible, responsive experiences that feel simple to use—even when the system behind them is not.

At MithyaLabs, I worked across healthcare, mobility, administrative tools, component systems, and an enterprise agentic AI platform. I collaborate closely with design, product, and backend teams while keeping the frontend reusable and maintainable.
