SENIOR SOFTWARE ENGINEER

Hi, I'm Waseem
& I build things
that scale.

Currently building distribution infrastructure at Tajir (YC W20), serving 100k+ stores across Pakistan. I obsess over clean architecture and products that genuinely solve problems.

About Me

I studied Computer Science at LUMS and have been shipping software since 2021. Backend services, native Android apps, cloud infrastructure, and everything in between. I think about systems end-to-end: from how the domain is modeled to how it runs in production. My tools of choice are Python, TypeScript, Go, and Kotlin, and what I care about most is getting the foundations right. Clean APIs, thoughtful abstractions, and code that's easy to change.

Beyond the day job, I contribute to open source, notably PandasAI and ng-select, and have published security research at ESORICS 2023. I like working across boundaries, whether that's backend-to-mobile, code-to-infrastructure, or industry-to-academia.
