Luis Casillas

Hi, I'm Luis, known as gwitchr to the internet.

I mainly contract for big beer company (Anheuser Busch) and for the Human Data team at spaceXAi and I'm always working on a couple of ideas, who isn't really?, no shortage of side projects, some more ambitious than others, but being a curious 🦝 and with a pretty resistant imposter syndrome I'm also always trying to brush up and learning something new. At AB-InBev I work on a data visualization tool used to plan about $100M a year of US advertising, and on a computer-vision platform that builds visuals for machine-learning pipelines. I also co-founded n12estudio, where I'm building Orbit, you should check it out.

This is my personal blog, you might find wildly different topics and subjects, so I tried to organise it for you 🎁, try filtering by tag of category. I might talk about many things, usually at once, sometimes in different pieces, it's not my mind unfiltered, that's what x(twitter) is for.
