Hi, I am Rafael

Rafael Ribeiro

Cloud Engineer at Neoception, GmbH

I am a passionate software engineer with 7 years of working experience. I have worked on a wide range of technologies, from frontend to backend, from full stack to microservices. I have a strong background and preference in Cloud Native technologies and Infrastructure. Im also passionate about the open source community and contributed to several projects in the cloud ecosystem. I’m also passionate about cryptocurrency and have founded the Helium DIY github organization, which aims to provide a sample way to run a Helium miner using only open source software. Big homelab fan, have a bunch of kubernetes clusters and other servers under my home-ops repository using Flux and Ansible together with Github Workflows to provision, update and automate everything running at my home.
