I build production-grade applications, scalable APIs, and AI-powered tools. Passionate about creating software that serves underrepresented communities.
About Me
At a Glance
I'm a software engineer with a background in full-stack development and a passion for building tools that serve underrepresented communities.
I've shipped production features for client-facing applications used by 300+ users, built and optimised 10+ RESTful APIs with Spring Boot, and maintained 96% test coverage across production features. I enjoy solving complex problems and making technical decisions that drive real impact.
I hold a BSc. in Applied Computer Technology from USIU-Africa (Nairobi, Kenya). Outside of work, I mentor emerging young women in tech through the Rewriting Code Club and build open-source tools for African language translation.
