What I'm looking for

I seek backend roles where I can build secure, scalable Java microservices, work with CI/CD and containerized deployments, and grow in system design and data-driven features.

I am a Computer Engineering undergraduate transitioning into backend development with hands-on experience in Java 21, Spring Boot 3, microservices, and containerized CI/CD deployments. I built a production-ready RESTful API (LibraryManager) with Spring Data JPA, OAuth2 security, and automated delivery on Render, and I bring 2.5 years of SAP systems analysis experience that strengthened my debugging and problem-solving skills.

My work emphasizes clean architecture, SOLID principles, and testable code—demonstrated by implementing role-based access control, layered designs, and automated pipelines. I am actively researching a Hybrid Recommendation System for my bachelor’s thesis, applying collaborative filtering and content-based techniques to improve cold-start performance and prediction accuracy.
