01 / What I do

An overview

I turn ideas into working software: responsive web apps, cross-platform mobile apps and the admin tools that keep products running. I care about clean, typed code, interfaces that stay in sync with their data, and access controls that are secure by default.

I'm studying Software Engineering at Khalifa Isyaku Rabiu University, Kano, and outside of work I'm into open-source software, tech communities, coding challenges and Linux administration.
