About

A little about me.

I’m a full-stack developer and computer science student at FAST-NU in Karachi, currently working as a Junior Software Engineer at KNYSYS. I build web applications with React, Next.js, and Node.js, with a particular interest in the systems behind the interface.

I’ve worked on authentication and real-time collaboration in SynapseFlow, an academic workspace that brings study tools and shared learning together. I also built Automata, which turns natural-language requests into validated automation workflows. In my professional work, I’ve developed integrations and data visualizations for a healthcare platform, spanning backend services and interfaces for different users.
