I developed a commercial management and stock control system with Java 25, Spring Boot, MySQL, and Docker. Its REST API supports transactional billing, customer management, and inventory control, with atomic stock validation and automatic inventory deductions.
At No Country, I designed entity-relationship diagrams and developed and documented REST endpoints, contributing to backend analysis and technical architecture with an interdisciplinary agile team. I also built a veterinary clinic management API and a console-based C++ dice game.
