Background
Twenty years building software, from native applications and compilers to 3D graphics and web platforms. I understand systems end to end: how they're designed, how they break, how to make them fast.
Built a guitar tuner app that outperformed the competition on precision, grew and maintained it for 7 years, and eventually sold it.
Polyglot: Portuguese, Romanian, English, Spanish.
What drives me: solving problems, shipping tools, learning how to do both better.

Les Misérables (Victor Hugo)
A book worth revisiting every decade. It reads differently each time.
The Feynman Lectures on Physics (Richard Feynman)
A fascinating account of how the world actually works, as much as we can figure it out anyway.
Friedrich Nietzsche
He looked at the world and wrote what he truly saw, with comprehension and without filter. A pillar of intellectual honesty.
