Iden Tumuhirwe

Software Engineer · Kampala, Uganda

I turn hard problems
into products
people rely on.

I'm a full-stack and mobile engineer in Kampala. I design web apps, native iOS and Android, and the cloud systems beneath them, and I care most about the work that keeps performing long after launch.
