Hi, I'm William Muli 👋

About me

I'm a software engineer and technical leader based in Nairobi. I enjoy building dependable products at the intersection of backend systems, AI, and thoughtful user experiences.

At Deel, I work on global payroll systems and agentic workflows for Akai. Before that, I helped build Brave Wallet across browser, backend, and blockchain layers.

I care about clear architecture, reliable systems, pragmatic engineering, and helping teams do their best work.
