WRITING & LEARNING

I’m studying computer science, building projects, and documenting what I learn along the way. This is one place for the work, the questions, and the life around it.

Work & experiments

Software, storytelling, and studies. The labels describe what exists, not what I hope to finish.

A personal software experiment inspired by my work at UPS. I’m developing the app and testing it with real users, making it one of my strongest sources of hands-on project experience.

Thoughts in public

A home for what I’m studying, where my career is going, and what technology makes me question.

Building while I’m still learning the basics

What happens when the projects move faster than my understanding, and how I’m trying to close that gap.

03 / BEHIND THE WORKA LITTLE MORE HUMAN

About me.

I’ve loved computers since I was young. Hardware was my first connection to them, and over time I became more curious about the software behind it. I tried mobile programming once, but didn’t continue. Back then, I had a different impression of the field. I also completed a bachelor’s in Librarianship (2017–2026).

Moving from Brazil to the US helped me focus more on my professional life. Meeting Angel, my wife, helped that focus grow. When I started studying Computer Science, I felt how much this field matched me. I enjoy building things, but understanding what happens beneath the surface makes me even more curious.

Today, I’m learning in two ways. Writing Python helps me build my foundations. Working with AI teaches me about planning and managing agents. MatrixLang has pushed my curiosity and creativity, while Graph Boost, a private project with my mentor, has introduced me to more of the engineering process.

I’m also building an employee manager from scratch in Python, putting what I know into practice and learning new things as I go. I’m still exploring where all of this might lead. For now, I’m enjoying the process.

04 / OFF THE CLOCKMUSIC & GAMES

Beyond the screen

Music came first. These are a few moments from that story, plus the games I keep coming back to.

01 / MUSIC2010 → 2017 → AFTER THE MOVE

From sax
to guitar.

I started playing alto sax in the orchestra at the church I attended. In 2017, Everaldo Pio and I founded A Casa 492. After moving to the US, I stopped playing with the band, but kept making guitar covers for Instagram.
