Hi, I'm Umar.
I build software that ships, scales, and solves real problems.

Building for the World, One Product at a Time
I started in 2019 building an Android food delivery app in Java and Firebase — nothing sophisticated, but it shipped to the Play Store and real people used it. That was enough to get me hooked. By 2020 I was deep into the MERN stack, taking on every project I could get my hands on.
In 2022 I landed my first international freelance project — a complete e-commerce platform for a client in New York. I delivered on time, learned how professional handovers work, and realised I could compete globally from day one. That same year I started mentoring 15+ final-year university students through their capstone projects, which forced me to explain not just what to build, but why.
Since 2024, I've been founding and shipping my own SaaS products — Casheir, Gasflow, Eleventh Mind, Concise Lesson, Brainvay, and Meals Cloud — handling everything solo: architecture, frontend, backend, AI integration, and deployment. I also take on select client work and share what I learn on YouTube. The goal is always the same: build things that work, ship them fast, and be honest about the trade-offs.

My Principles
Ship Fast
A working product in users' hands is worth more than a perfect product in a staging environment. I move fast without cutting the corners that matter.
Think at Scale
I build for where the product is going, not just where it is today. Architecture decisions made at the MVP stage can haunt you for years — I try to get them right early.
Deliver Value
The code is a means to an end. I care more about whether a product actually solves the problem than whether it uses the latest framework.
