• Own end-to-end delivery on a production building-management ERP: 1,000+ users, 10+ business modules (inventory, project costing, quotations, HR, maintenance).
• Spring Boot services and REST APIs with Spring Data JPA/Hibernate and PostgreSQL; Spring Security with JWT and RBAC.
• Angular/TypeScript frontends with RxJS, Reactive Forms and reusable components.
• ~40% faster slow screens and reports (SQL and index tuning) · ~30% fewer backend calls per screen (batching and caching).
• ~70% test coverage on core modules (JUnit, Mockito) · ~25% fewer repeat production incidents through root-cause fixes.
• Work directly with the client; review code and mentor developers in two-week Agile sprints.
