     bio: "Olá, tudo bem? My name is Pedro and I'm a Cloud Engineering Manager at Pegasystems. I've worked for companies like IBM, Luxoft, Eaton, and now Pega. These days, my focus is on Cloud, SaaS, DevOps and mostly, leadership. When I'm not catching up with my Steam games backlog, I love participating in conferences, hackathons, learning new things and meeting new people. See you around!"
