About

Building systems
that matter.

I'm a Senior Software Engineer based in Mumbai with 4+ years building full-stack products across fintech, hospitality, and healthcare. Currently at Travelex, owning the bank notes calculation engine and leading event-driven backend architecture for high-volume FX transactions.

I work across the entire stack — from architecting resilient Node.js backends to crafting modular React frontends. I use AI tools strategically to compress delivery timelines without cutting corners.

Beyond full-time work, I freelance on digital products for luxury hospitality clients — including the digital dining platform for Five Palm Jumeirah, Dubai.
