About Me
Engineer, builder, and problem solver
Full stack engineer, backend and platform focused
I build systems that hold up in production.
I'm Nasr Hassan Mpalang'ombe, a full stack engineer based in Tanzania. I build reliable APIs, web platforms, and IoT systems for teams that need software to work in the real world.
My core backend language is Go. I also work with TypeScript, Laravel, PostgreSQL, Docker, Linux, and networking, and I can take a product from data model to production without handing it between teams.
