Osman Gani Khan
Masum

This is me, I'm a software engineer with 7+ years of professional experience designing and building the systems that keep products running. From API design and database engineering to the communication protocols, web servers, and message formats underneath them. I care about the craft: software that's not just correct today, but reliable, observable, and easy to extend a year from now.

My work spans logistics, e-commerce, EdTech, audio/video streaming, ride-sharing, event-driven systems, IoT, and blockchain. Architecting distributed transactions, billing systems, and observability standards for teams running dozens of services in production. I'm drawn to problems where the constraints are real: correctness under failure, cost at scale, and systems that have to keep working while you change them underneath.

Beyond the code itself, I'm a researcher at heart, writing about distributed systems, Go, and AI/ML, contributing to open source, and mentoring engineers earlier in their careers. I stay proactive and curious, because the best part of this work is still getting better at it.

I occasionally take on contract and consultancy work. See below for what I offer, or reach me directly at osmanmasum.cs@gmail.com.
