About

A bit about me

I'm a full-stack-oriented Front End Engineer based in Pune, India. I specialize in building high-quality web applications with modern JavaScript frameworks and have a deep passion for creating intuitive, accessible user interfaces.

I've worked across SaaS and B2B platforms — from leading frontend architecture for enterprise billing systems at Prosperix, to delivering high-traffic features serving millions of users at Paytm. I care about clean code, strong collaboration, and mentoring fellow engineers.

Outside of work, I build side projects like Tribexa.io and take on freelance work to keep pushing my skills. I hold a B.E. in Computer Science from the University of Pune (2018).
