Who I Am

I'm a Senior Software Developer based in Hyderabad, India with 4+ years of professional experience crafting cloud-native, scalable microservices and modern web applications.

My core strength lies in designing end-to-end solutions — from backend Java/Spring Boot microservices and AWS infrastructure to Angular SPAs — always with a focus on performance, security, and developer experience.

I thrive in environments where I can tackle hard architectural challenges, mentor junior engineers, and ship software that matters.
