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.
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.

My video channel on PeerTube — tech, live streams, chats and a bit of life, all on the fediverse, no algorithm and no ads. You can follow it straight from Mastodon.

My knowledge base
Technical notes, cheatsheets and how-tos I use daily — Kubernetes, Docker, nginx, Proxmox, Linux, mail and more. Open to everyone.

Services I host
Free, open source services I host, run and keep online — on GCN.
My technical home
GCN.sh is my space to study, discover and share knowledge about technology. It's where the bolha.io universe and the bolha.us instance of the Brazilian fediverse were born.
