What I Do

Full stack developer building production APIs and data-driven platforms that handle real-time traffic. At Zone01 Kisumu, I cut API response times by 40% while supporting mobile and web clients for internal platforms used daily by hundreds of users. I think in systems; from database queries to polished user interfaces, I understand the full picture and own the whole stack from design to deployment.
