About me
Builder by nature
About me
Builder by nature
Hi! I'm Gabriel, a 20-year-old software developer and entrepreneur from Brazil.
I started programming at 18 because I had ideas I wanted to turn into real products. I taught myself through practice, online content, and a lot of experimentation, starting with HTML, CSS, and JavaScript and gradually moving into complete applications, APIs, databases, payments, automation, and AI.
I'm persistent, communicative, and quick to learn. When I don't know how to build something, I research, experiment, and keep going until I find a solution.
I'm currently looking for remote opportunities where I can contribute, learn from experienced developers, and help build products that solve real problems.
