Bernardino Rosa

I’m a software engineer with 9+ years of experience in backend development (Java, Spring, SQL) and large-scale telecom integration (4G/5G RAN). I focus on debugging, optimizing business flows, and delivering complete solutions in regulated banking and enterprise environments.

At BNP Paribas, I implemented and optimized backend features that supported evolving business rules. I reduced database script reliance by 70% and improved onboarding efficiency by 20% through clear technical documentation, while also providing production support by identifying root causes and delivering fixes for critical issues.

Previously at Infosistema, I developed full-stack web portals using Java, Angular, Spring, and Docker, and built ETL middleware systems (Informatica, Pentaho, Java) for financial clients. I also implemented UiPath RPA solutions, increasing operational efficiency by 15%, and worked on banking and non-technical rule management (FICO Blaze Advisor) across multiple domains.

As a RAN Integration Engineer (contractor), I’ve delivered remote technical support for 4G/5G site integration—resolving RAN alarms, ensuring network stability, and preparing and validating site-specific scripts and configuration files. I’m known for rapid learning and adaptability from years of consulting, and I’m comfortable with microservices concepts, AWS fundamentals, and container orchestration (Docker, Kubernetes).
