Full Stack Engineer and DevSecOps practitioner based in Kisumu, Kenya. Currently undertaking a software engineering apprenticeship at Zone01 Kisumu, specializing in Go, distributed systems, container orchestration, CI/CD, and secure software delivery.

My background in Geographic Information Systems (GIS) and remote sensing shapes how I approach engineering: systems as networks, data as terrain, and security as a foundational concern rather than an afterthought.

Self-hosted application deployment platform focused on simplifying application delivery and infrastructure management.
