Products I've built and shipped.
A few projects that show how I work: real constraints, real users, and the engineering that keeps an app trustworthy after launch.
433 — Home of Football
Sports media platform for 77M football fans, 2M+ downloads
Live match centre with line-ups and player ratings, favourites, profiles, daily quizzes, wallpapers and a viral video feed for one of football's biggest fan communities — built in React Native with a WebSocket-driven real-time layer.

The youth football development platform — sensors, platform, AI
Youth football development platform: session stats from JOGO's in-sole sensors (distance, sprints, shot speed, ball touches, leg distribution), trainer feedback, video analysis, a coach web dashboard — and Jogo AI match predictions with win probabilities, goals and bookings.

04About
Engineer first, designer by habit.
I'm a senior frontend and mobile engineer who cares as much about the 60fps feel of a screen as the pipeline that ships it. Over seven years I've led frontend architecture across web dashboards and iOS/Android apps for companies in the Netherlands, the US and Pakistan.
The highlight reel: the 433 Football app (2M+ downloads) with a live match centre that held 99.9% uptime through the 2022 World Cup; Delphyr.ai, a healthcare analytics platform on Next.js and tRPC; Eatsy, Pakistan's first digital dining-payment app for Bank Alfalah; iYuga's drag-and-drop content platform; the Jubilee Life Insurance policyholder app and Peekaboo Guru's React Native relaunch; and, right now, Picasse SOS — an emergency-alarm app for lone workers where I own the whole mobile pipeline.
I like typed codebases, boring infrastructure and real-time features that don't fall over. I've mentored junior developers, set code-review standards and cut bundle sizes by 35% and load times by 40% along the way.
I work remotely from Karachi with teams across Europe and North America, and I'm looking for a full-time remote role where quality on mobile really matters.

Ship, then sharpen
Working software in users' hands beats a perfect plan. Iterate with real telemetry.
Real-time, done right
WebSockets, WebRTC and SignalR at scale — live data that stays consistent across web and mobile.
Boring infrastructure
TypeScript everywhere, CI/CD, automated tests. Excitement belongs in the product.
