About

I'm a backend developer — the APIs, the databases, the business logic that makes applications actually work. I spent 2 years at Capgemini working on enterprise Java applications — my core was designing REST APIs in Spring Boot, handling business logic, and managing data with JPA/Hibernate and PostgreSQL. Real production work, real users, real team of 10+ engineers shipping in Agile sprints. What I'm good at: → Building REST APIs that are clean, versioned, and actually easy for frontend teams to work with → Designing PostgreSQL schemas that scale — normalisation, indexing, query performance → Microservices architecture — structuring services so they're independently deployable and loosely coupled → Writing JUnit tests that catch problems before they become production incidents Outside of work I've built two projects from scratch — a Library Management System and a Job Portal — both in Spring Boot with microservices, JWT auth, and PostgreSQL. Because I learn by building, not watching tutorials. I'm AWS Certified, immediately available, and looking for a backend or full stack role where the problems are complex and ownership is real.
