Software Engineer

David Félix

I build fast, reliable products, from React and TypeScript frontends to cloud infrastructure and enterprise integrations. I turn complex systems into software people actually enjoy using.

What drives me

Building things that matter

I'm driven by products that make a real difference, tools that simplify people's lives and create meaningful change. I love being handed a hard problem, pulling it apart, debating the trade-offs, and landing on a solution that actually works. Growth keeps me going: I'm always experimenting with new ideas, learning new tools, and pushing myself to build better than I did yesterday.

I've also built several other products throughout my career and at my current company that I can't showcase here due to NDAs.
