What I'm looking for

I seek product-focused engineering roles on collaborative teams where I can build scalable e-commerce or data-driven features, contribute to open source, and grow technically in modern JS and backend systems.

I am a full-stack engineer with a strong background in building performant, user-centered web applications across startups and remote teams.

I have delivered subscription and e-commerce features, membership systems, and custom calendar tools using modern JavaScript frameworks, Node.js, and headless commerce integrations, helping increase conversions and average order value.

I contribute to open source projects, including a cross-platform coding practice terminal app and a soccer data visualization dashboard, demonstrating my skills in Python, R, data visualization, and tooling for developer productivity.

I hold a Bachelor's degree in Statistics (first class honours) from the University of Nairobi and bring a disciplined, data-informed approach to product-focused engineering work.
