I am a performance-driven software engineer with hands-on experience designing and deploying scalable backend systems, APIs, and microservices. I specialize in Java (Spring Boot) and cloud-native architectures that prioritize reliability and performance.
At KCB Bank Group I developed and deployed microservices supporting core banking transactions, optimized RESTful APIs to reduce latency by 35%, and containerized applications to improve deployment efficiency by 40%.
