about me

Portrait of Diego V. Feder, Brazilian Software Engineer

Diego V. Feder

Hi there 👋
I’m a Brazilian software engineer working remotely since 2020. I build scalable, reliable applications for a wide range of companies.

Since joining Tarmac.io, I've been contributing to full-stack projects in education, fintech, healthcare, and more. I also take on select freelance work, helping clients launch websites and apps that solve real business needs.

Looking to collaborate or just want to connect? I’m easy to find online at @diegovfeder.

When I’m not coding, I’m usually wakeboarding or wakeskating — one trick (or wipeout) at a time.
