Rex mubita

I’m a results-driven platform and software engineer with a strong foundation in distributed systems and cloud infrastructure. I design scalable platforms, automate deployments, and build reliable developer tools using clean code and thoughtful architecture.

At Witgal (Jan 2021–Dec 2024), I designed and maintained shared APIs, frameworks, and services that improved developer velocity across multiple teams. I built workflow automation tools that reduced deployment time by 30%, implemented scalable monitoring and alerting to improve production reliability, and collaborated cross-functionally to unify siloed solutions into company-wide platforms.

Before and alongside that, I developed responsive full-stack web applications at Mulenga Enterprises (Feb 2025–Mar 2025) using Python and JavaScript, improving performance by 40% through secure authentication and SQL optimization. Earlier, I worked as a Software Engineering Intern at BWS (Jan 2024–Jun 2024) on Go distributed system components, observability research, and monitoring dashboards—then carried that into projects and mentoring around fault-tolerant distributed platforms and cloud-native deployments.
