I'm André Brandão, a full stack developer building platforms and NixOS systems.

Full Stack Developer at A3Data. I co-founded a company with a professor from PUC-MG and shipped systems that are still running in production. I own the whole stack, from Terraform to UI, and run a declarative NixOS homelab at home.
