I'm a Software Development graduate and passionate Java developer with a strong focus on clean architecture, testing, and real-world problem solving.

I’ve built multiple projects from scratch, including a fully-featured banking system and an Inventory Management System API, showcasing my backend development skills with Java, Spring Boot, and databases.

• ✅ Java (OOP, Interfaces, Inheritance, Generics)
• ✅ JDBC with MySQL + H2 for testing
• ✅ Spring Boot, Spring Security, Spring Data JPA
• ✅ Unit & Integration Testing (JUnit + Mockito)
• ✅ REST API design & JWT Authentication
• ✅ CI/CD with GitHub Actions + JaCoCo + Codecov
• ✅ PostgreSQL & H2 Database
• ✅ Clean architecture with full separation of concerns
• ✅ Environment-based configuration & secure password handling

A console-based banking system where users can:

• Register/Login securely
• Create and manage multiple accounts
• Deposit, Withdraw, and Transfer funds
• View transaction history
