About
I’m Rico Leandro Cruz, a full-stack developer with 10+ years of experience building and supporting enterprise web applications. I work primarily with Java (Spring Boot) on the backend and modern front-end frameworks like Angular and React to deliver reliable, secure, and performance-focused solutions.
Over the years, I’ve contributed to banking, insurance, and IT environments by developing microservices/APIs, resolving high-priority production issues, and optimizing database systems in Oracle. I also enjoy collaborating across teams, mentoring through code reviews, and using security/testing tools to improve code quality and stability.
