Hi, I'm Brian • Java Developer based in Vienna, Austria. I build backend systems that handle real operational complexity. My latest project is RentIt+, a production-deployed offline-first equipment rental and inventory management system - Spring Boot, JavaFX, Vue 3, PostgreSQL/SQLite, hexagonal architecture, custom sync protocol with conflict resolution, and full CI/CD releasing platform-specific installers on every Git tag. Live at rentitplus.dev Background in electronics/embedded systems and six years running technical operations in live event logistics before returning to software development full time.
