About Me

Alex Castañeiras Bueno

Since I was a kid, I really liked the idea of creating things with code. It always surprises me how fast technology can evolve and how it opens up new possibilities to turn ideas into reality.

Outside of programming, I enjoy staying healthy and creative. Fitness and making music are two of my favourite ways to unwind and express myself. I’ve also explored video editing with tools like After Effects and Premiere, a hobby that has allowed me to channel my creativity in another ways.
