Java Backend Developer | Spring Boot · REST APIs · Docker | Built AI-Powered Career Platform

About

I build backend systems that actually work — not just in theory, but in production. Over the past year at TCS, I've been designing and shipping RESTful APIs, building data persistence layers with Spring Boot and Hibernate/JPA, and debugging the kind of issues that only show up when real users hit your system. I don't just write code — I think about why it breaks and how to make it not break again. Outside of work, I built Career Agent AI from scratch — a full-stack platform where job seekers get AI-powered resume scoring, a LLaMA chatbot for career guidance, and live job recommendations via JSearch API. JWT + OAuth2 auth, Dockerized deployment, cloud-hosted MySQL. The whole thing. I built it because I wanted to solve a real problem, and because I wanted to prove to myself (and anyone reading this) that I can ship end-to-end. My core stack: Java, Spring Boot, Spring Security, Hibernate/JPA, MySQL, Docker, REST APIs. I'm comfortable across the backend and can hold my own on the frontend when the project needs it. What I'm looking for next is a Java Developer or Backend Engineer role at a company where the work is real, the team is sharp, and there's room to grow fast. Startups and mid-size product companies especially — I move quickly and I'm an immediate joiner.
