Objective

Java Backend Engineer focused on building reliable Spring Boot microservices and clean backend systems. I work on designing REST APIs and building services that scale and stay stable in production. I enjoy breaking down complex workflows, improving performance and reliability, and owning features end-to-end—from implementation to demos and feedback. Currently building and refining backend systems while exploring better ways to design and operate microservices. Open to backend roles, collaborations, and interesting engineering problems.
