Hi, I'm Guille.
I'm a Technical Lead for Data & AI Solutions at Flock IT. I also contribute to open-source Bitcoin observability projects, supported by a grant from B4OS, part of the nonprofit LibrerÃa de Satoshi.
Here I post monthly progress on my projects and the material from the talks and workshops I give.
Feel free to reach out to talk on:
