Personal

Welcome!

I'm a Linux sysadmin, open source enthusiast — networks, devops, gitops, cloud native and AI. I created, host and run GCN.sh and the bolhaverso — the free, no-algorithm, no-ads networks of the Brazilian fediverse. This is my little corner: who I am, where to find me and what I've been sharing.

Bolha

Founder of Bolha.io

I created, host and maintain the Bolha.io Collective — one of the free networks of the Brazilian fediverse, no algorithm and no ads. One of the projects I'm most proud of.

GCN.sh
