Brian Mthembu

I’m an OCP Certified Java Developer with 4 years of experience building and maintaining production-grade Spring Boot APIs, CI/CD pipelines, and Dockerized services. I take full ownership of features end-to-end—from design to deployment—while improving system reliability and performance. I’m comfortable working in distributed teams and communicating technical decisions clearly.

In my current Support Software Developer role, I diagnose and resolve production issues in a Dockerized Linux environment, improve reliability, and reduce resolution time. Previously at Vox Telecommunications, I developed Java 8/11 back-end services (REST APIs, Hibernate, MySQL), improved validation and error-handling to reduce production bugs, and built Selenium-based smoke tests to speed up regression cycles—progressing from intern to Junior Developer. I also enjoy full-stack delivery, with growing expertise in Angular, and I’ve built projects like a real-time Spring Boot + Angular analytics dashboard, JWT-secured RBAC APIs, WebSockets-based chat, and an insurance quote engine that cut quote turnaround from hours to seconds.
