Software Engineer & Business Technology Consultant · Nairobi, Kenya
I help businesses build, automate and grow with technology.
- Lead software engineer at Buzlin Holdings Inc for Buzlin (a marketplace and service-booking platform) and BuzRyde (a ride-hailing service in Canada, run by the subsidiary BuzRyde Inc).
- Founder & Lead Software Engineer of Teevexa Ltd, a software development company that delivers custom software, AI agents and production-ready apps for businesses.
- Trained as a chemical engineer, which taught me to look at a business like a process: inputs, outputs, bottlenecks and the points where things quietly go wrong.
- I start with the business problem, recommend only what is needed, and build solutions that keep working after launch.
