Adrián Gómez Domínguez

Full Stack Web Developer & IT Infrastructure Administrator

Since I was little, I have asked myself the same question whenever something works well: How did they do it? That curiosity is what led me to computer science. For me, programming is the superpower of transforming an abstract need into a useful tool that people can use in their daily lives. But software doesn't live in isolation. I am passionate about economics because it is the engine that drives our world, and I am obsessed with airplanes and space exploration because they represent the limit of what we are capable of building. If you are looking for someone who doesn't just write code, but understands the global context, strives for maximum efficiency, and aims for the stars (literally), you are in the right place.
