Profilo professionale
Java Developer with over 6 years of experience across enterprise environments in the energy, finance, gaming, and public sector industries. Throughout my career I have collaborated with leading organizations such as Enel Group, Lottomatica, Ericsson, and Accenture on behalf of Italian IT consulting firms.
My core expertise lies in Java ecosystem development — from Java 8 through to Java 21 — with a strong focus on Spring Boot, microservices design, system integration, and database performance optimization. I am comfortable owning the full backend lifecycle: from architecture and data modelling, to implementation, refactoring, testing, and continuous maintenance.
I care deeply about code quality: I apply clean code principles, enforce test coverage above 80%, and use tools like SonarQube to maintain high engineering standards.
4-years working in London allowed me to develop the ability to adapt to a different environment and culture by facing new challenges and cultures.
