What I'm looking for

I’m looking for a Java backend role where I can ship scalable REST APIs, build secure Spring Security auth, and deliver LLM/RAG features—owning system design and clean, production-ready delivery.

I’m a Java Backend Developer focused on building scalable REST APIs, AI-powered systems, and secure authentication pipelines. I’ve architected and shipped two end-to-end backend systems live on cloud infrastructure.

I reduce manual support effort by ~60% by pairing LLM automation with RAG pipelines. I’m an early adopter of Spring AI and Retrieval-Augmented Generation in Java—one of the differentiators I bring even at a fresher level.

I enjoy distributed systems, clean API design, and shipping software to real users. Through an end-to-end internship cycle and production projects, I’ve delivered reliable APIs with Spring Boot, Spring Security, strong testing habits, and Dockerized deployment for consistent runtime environments.
