About Me

I'm a highly analytical Backend Engineer with a Mathematics background and 6+ years of experience in software development, system architecture, and technical mentorship.
Currently sharpening my expertise in Java and Spring Boot to build scalable, high-performance enterprise APIs. I'm passionate about clean code, microservices, and cloud deployment.
I believe in continuous learning and sharing knowledge, which is why I've mentored 50+ junior developers and built comprehensive learning modules for Spring Boot and QA Automation.
