Leon M. Njeru: Full-Stack & DevOps Engineer
I design, build, and deploy production web platforms end to end: React and Next.js frontends, Java Spring Boot and Python services, and Dockerized deployments on Linux behind Nginx. As Product Lead for an enterprise monitoring platform, I improved system efficiency by ~50% through backend and API optimization. I'm an Information Security major who automates releases, designs secure APIs, and leads engineering teams.
