About Me

A developer who loves clean code

Hi, I'm Mercy Nyomenda — a passionate full-stack developer based in Nairobi. I specialize in building performant, scalable web applications that solve real-world problems with clean, maintainable code.

With experience across startups and enterprise environments, I've led projects end-to-end — from architecture decisions and backend APIs to pixel-perfect UIs and CI/CD pipelines.

When I'm not coding, you'll find me contributing to open-source, writing technical articles, or exploring new technologies.
