Sobre mim:

I’m a Software Developer with over 3 years of experience, specializing in Back-End development with Node.js (NestJS) and Java (Spring Boot). I focus on building robust RESTful APIs, automation through web scraping, and integrating systems using MySQL, PostgreSQL, and MongoDB.

On the Front-End, I work with React.js and TypeScript, applying modern UI libraries and design systems to create responsive and user-friendly interfaces.

I’ve contributed to teams at companies like Martinelli Labs, Sizebay, and Docspider, working on scalable systems with strong attention to performance, clean code, and CI/CD practices.

I'm passionate about solving real-world problems through clean, maintainable, and efficient code — and I’m always ready for new challenges that deliver value to users and businesses.
