Software Engineer at StockX
I build things that make the web feel effortless. Right now I'm focused on real-time live commerce, sub-second data synchronization, and high-scale auth — the kind of low-latency interactive infrastructure that powers millions of concurrent users.

About Me
I'm a frontend engineer who's spent the last 6+ years obsessing over the details most people never notice — the 200ms that makes a checkout feel instant, the auth flow that doesn't make you think, the payment page that just works.
I've shipped code at a sneaker marketplace, a D2C checkout platform, a gaming studio, and one of India's largest banks. Different industries, same obsession: making complex things feel effortless.

StockX
Leading live commerce, payments and auth on the frontend. Everything between "going once" and "it's yours" — that's my domain.
- Architecting StockX Live. Syncing video, chat, and sub-second bidding instantly — millions of users, zero lag.
- Built the Apple Pay and PayPal one-click checkout flows. Tap once, done — no forms, no friction.
- Added Cash App, Afterpay, and Buy Now Pay Later so people can pay however they want.
- Stitched together StockX Credit, gift cards, and store balance into one smooth payment experience.
- Took the checkout from five confusing steps to one clean page. Drop-off went way down.
- Migrated every user session to passwordless login with passkeys.
Frontend Engineer
Shopflo
Checkout platform for D2C brands. Built it from the ground up — processed over 200 crore a month.
- Built loyalty programs, wallet integrations, and split payments. Anything that gets someone from cart to "order placed" faster.
- Redesigned the entire checkout UI. Merchants actually liked it enough to switch from their old flows.
- Made a self-serve onboarding tool so new merchants could go live in hours instead of days.
Full Stack Developer
SuperGaming
First time building for games. Silly Royale hit a million installs and I worked on both server features and internal tools.
- Built "Rent a Skin" — turned out to be a huge revenue driver (300% boost).
- Created internal tools so the team could manage configs without needing engineering support.
- Built Tegro's pre-registration that pulled in half a million sign-ups before launch.
IT Business System Analyst
Axis Bank
First role out of college. Fintech integrations at one of India's largest private banks.
- Helped integrate Account Aggregators — the framework that lets users securely share financial data across banks.
- Built the Forex Card management module. Served millions, taught me about building at scale.

Outside of work, you'll find me on a football pitch, planning my next trip, or arguing about Manchester United's midfield. I believe good software — like good cooking — is all about taste, timing, and knowing when to keep it simple.
I also like capturing moments when I travel — some of my favourite shots are right here.
