About

I'm a full-stack developer from Rawalpindi with a BS in Computer Science (2025). I like the parts of a product that are easy to get wrong: who is allowed to do what, how a Stripe payment flows back into the app, and how two people see the same board update at the same moment.

My latest project, FlowBoard, is a multi-tenant SaaS with role-based access, Stripe subscriptions and a real-time Kanban board, covered by 43 automated tests that run on every push.

I'm looking for my first full-time role, on a team that ships often and cares about getting the details right.
