About Me

I enjoy solving complex problems and building all kinds of software. What fascinates me most about Software Engineering is that if something can be imagined, it can also be built.

Who I Am

I'm a tech enthusiast and software developer focused on creating clean, efficient, and user-centric applications. My journey began in Electrical Engineering at UTFPR (2020-2024), where I built a strong analytical foundation. However, I discovered my true calling in Software Engineering: the incredible power to build virtually anything from scratch.

I am driven by the fascinating possibility of transforming lines of code into high-impact solutions and scalable businesses. For me, programming is the ultimate tool for innovation, allowing the creation of products that can reach millions and change the way we interact with the world.

I specialize in backend development with Java and Spring Boot, while also crafting modern frontends with React and Next.js. I believe in writing code as an engineer, prioritizing Clean Architecture, performance, and the scalability required for the next generation of software companies.

I am obsessed with technology and dedicated to learning something new every single day. For me, it's not just about writing code. It's a constant pursuit to refine my craft and become the best engineer I can be.
