About
Who I am
I'm a Module Lead and Senior Java Backend Developer based in Karachi with over a decade of hands-on experience designing and delivering enterprise software. My core strength is backend architecture — building systems that are clean, performant, and maintainable at scale.
I gravitate toward fintech, where precision and reliability matter most. I value automated testing, disciplined code review, and writing code that a future developer will actually enjoy reading. Outside of full-time work, I build side products that solve real problems — like MenuQR.
