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.
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.
Tajir
YC W20Senior Software Engineer
- Architected and led a team building a full-stack platform using Python, Kotlin (Android/MVVM), and TypeScript (React) with Domain-Driven Design, serving 30K+ DAU and processing 10K+ orders daily
- Drove 42% net revenue growth by designing seven-day delivery and automated order carryover
- Reduced operational costs by 31% (4.5% → 3.1%) through delivery optimizations including zone-based routing, parking spot allocation, and in-sequence delivery
- Engineered GPS tracking and route optimization, achieving 23% fuel savings and 8% higher delivery acceptance

Let's build
something great together.
I'm always looking for the next hard problem to solve. If you're building something ambitious or just want to nerd out about systems design, I'd love to hear from you.
