About Me

Backend Software Engineer from Brazil focused on Java and Spring Boot. I build and evolve APIs and integrations used in critical banking workflows, where reliability, security, and clear contracts matter as much as delivery speed.

Day to day, I work with REST and SOAP services, relational databases, authentication with JWT / OAuth2, and the practical side of modernizing legacy stacks (JSP/JSF/Thymeleaf) without breaking production systems.

I also use AI tools as part of my engineering workflow — for faster exploration, code review support, refactoring ideas, and clearer documentation — while keeping ownership of design decisions, edge cases, and production quality. I am actively learning how to apply LLMs in backend products (assisted coding, internal tooling, and API-based integrations), not as a replacement for engineering judgment.

This site is my interactive portfolio: Beecrowd-inspired challenges solved in Java, with readable code, explanations, and a live runner so you can see how I approach problems — often looking for simpler, more elegant solutions instead of only “passing” the case.

I am looking for remote opportunities abroad where I can contribute to backend systems, collaborate in English (B1 and improving), and keep growing in distributed architecture and AI-assisted development. Reach me at kleber-r@outlook.com.
