// about

I build software that ships.

My resume in three stanzas. Scroll.

01

Three years. Production systems. Real users.

At Mahaana (YC W22) I architected the customer & corporate SPAs that 15,000+ Pakistani savers used to onboard their save+ and pension accounts. Before that I led Automily at mParsec — a GenAI QA-automation platform — and shipped DreamStream, the IFE platform now flying on PIA aircraft.

02

Framework-agnostic, but opinionated.

React and Next.js are where I spend most of my craft. ASP.NET Core and FastAPI are where I reach when the contract gets serious — events on Azure Service Bus, microservices, queues that don't lose messages. The framework is a tool. The system is the product.

03

I work best with people who care about UX as much as system design.

If your roadmap reads “ship fast, but it has to feel right”, we'll get along. I bring agency-grade frontend craft and the backend depth to back it. I work with freelance clients, joining startups as a founding engineer, and short-term contracts with engineering teams who need extra horsepower.

// stack
