Profile

About

I'm a product-minded software engineer who enjoys working at the intersection of interface design, frontend architecture, and emerging technology.

I've built products from the ground up, worked across the stack, and spent much of my recent work exploring how AI can become part of everyday software workflows rather than simply another feature.

I care about building software that is useful, understandable, performant, and maintainable.

  • Based in Nairobi, Kenya
  • Remote-friendly
  • Open to frontend / full-stack opportunities

Principles

How I think about engineering

  • Usability
  • Accessibility
  • Performance
  • Security
  • Testability
  • Scalability
  • Developer Experience

I try to treat these as design constraints rather than things to add at the end.
