About me

I am a Back-End Java Developer with hands-on experience in creating high-performance RESTful APIs and process automation. I specialize in the Spring ecosystem, including Spring Boot, Security, and Data JPA, and I implement robust data protection solutions using advanced encryption techniques such as AES-256. I am committed to delivering optimized systems and adopting clean code practices to ensure maintainability and quality.

My career goal is to join a software engineering team focused on innovation and information security, where I can add value by developing scalable and secure enterprise architectures. I have experience designing and developing robust web solutions aligned with business rules and client objectives. I also automate operational processes through bot creation and maintenance, improving execution time and minimizing structural failures.

I rigorously apply Clean Code principles, SOLID design principles, and version control with Git to ensure software quality and maintainability. In a practical project, I implemented advanced encryption protocols to manage credentials, enhancing data security and reducing vulnerabilities by 20%. I optimized backend data flow and architecture, accelerating request response times by 30%.

I architect scalable API infrastructures capable of handling up to 10,000 simultaneous requests without service interruptions. I ensure system reliability by achieving 95% automated test coverage within the Spring Boot ecosystem. I am proficient in Java 17 and SQL, and I use frameworks and technologies such as Spring Boot 3, Spring Security, Spring Data JPA, and Lombok.

I am fluent in Portuguese (native) and have technical English skills for reading and documentation. I am eager to contribute my expertise and grow professionally in a challenging and innovative environment.
