Arturo Macías

I'm an artificial intelligence engineer with expertise in building accessible, intelligent systems. I like coding useful tools and look out for the little details that elevate user experience.

Right now I'm working with AI agent frameworks and machine learning models for digital signal processing. I also lead the team at Webra, where we build fullstack websites and integrate AI where it actually makes sense.

I've worked at startups like Webra and Stamn, and at fintech companies like Urdaten. On the side, I built an AI vocal remover using deep learning audio processing. I'm planning to add support for more instruments when I get the time.

In my free time, you can usually find me studying (no, really) cloud and cybersecurity concepts. I also like to constantly modify my Linux configs or just try out different distros. When I'm not in front of a computer screen, I'm probably playing tennis or the guitar.
