JonathanReisCom/README.md

Hi, I'm Jonathan Reis

I am a Senior Tech Lead and software developer with a strong background in SRE, DevOps, and cloud engineering, based in Rio de Janeiro, Brazil.

I currently work as Tech Lead for Sportsbook Experience at Flutter Brazil, helping teams build reliable products around sports betting, payments, authentication, reporting, BI data flows, scalability, and customer experience.

My main focus today is software development and technical leadership. On the programming side, I am focused on Go, while still using my DevOps and cloud background to help teams ship reliable systems.
