About me

Journey, code and coffee

Mid-level Fullstack Developer
Rio de Janeiro, Brazil
Open to remote work

I started learning to code in 2021, on a one-year course at Trybe. The first job came in 2023: I joined Crase Sigma as a trainee and was promoted to Junior there, working on a mobile app, Laravel APIs and data locked inside COBOL.

At the end of 2024 Solution TI came with a chance to step up and I took it. Not long after I also joined MJV, the consultancy through which I serve a large insurance client, focused on the internal systems the developers themselves use. Alongside that, I’m studying Information Systems at UVA.

Off the clock

Coffee at Starbucks ☕️, time with my family 👩🏻‍❤️‍👨🏻 and the gym 💪. Also a cat dad, as the photo gives away.
