Building the web
since 2015

I'm a Senior Frontend Developer with over a decade of experience crafting digital products that are as beautiful as they are functional.

For 5 years at Zoho Corp, one of the world's largest SaaS companies, I led the frontend development of Zoho Flow – building the entire UI from scratch with pure vanilla JavaScript.

My specialty? No frameworks, just clean code. Whether it's React, Next.js, or custom component systems – I bring enterprise-grade thinking to every project.
