I'm a front-end & full-stack developer based in Islamabad, Pakistan, building web products end to end. I work across modern JavaScript/TypeScript frontends and multiple backend stacks — shipping everything from marketing sites and complex dashboards to browser extensions and npm packages.

I care deeply about performance, accessibility and clean, maintainable code — and I love turning complex flows into simple, delightful interfaces that people genuinely enjoy using.
