Full-Stack Dev & AI Engineer · Bengaluru
When you hire me, you get someone who's done this before — at scale
I have 5+ years of professional experience — from building AI chatbots at Celebal to supply-chain apps at Collabrix Inc., to two years deep inside AU Small Finance Bank. At AU I owned the full product cycle on four major internal platforms: AU HUB (50K+ daily active users, 50+ micro-apps), Sampark (task & lead management for RMs with Exotel calling integration), Drishti (3D compliance dashboard for HODs & SPOCs), and Niyantaran. All production, all regulated, all zero-downtime. That's where I earned the Star Award.
Beyond product work, I've designed and built 10+ business portfolios for clients across industries — landing pages, multi-section sites with booking flows, contact forms, and brand storytelling — each crafted to convert visitors into leads.
I don't need hand-holding. I ask the right questions upfront, flag risks early, and deliver something that works in production — not just in a demo. Whether it's a startup's first app, a business portfolio, or a complex enterprise integration, I bring the same discipline. Currently deepening that with an M.Tech in AI & Data Science at IIT Patna.
Off the clock: music production, cooking experiments, and losing sleep over chess puzzles.

How I work
Client first, code second
Every project starts with a business problem, not a tech stack. I figure out what success looks like for you before writing a single line.
Async by default
Weekly Loom updates, shared task boards, Figma previews before builds. You always know where things stand.
Own it end-to-end
From architecture to App Store submission. No handoffs, no "that's not my part". I carry it to the finish line.
