Hello World!

Fabiano Santos Florentino.

Father of Inácio and proud husband of Jullyana! Yes, two L’s and a Y :)

About me!

I am a Backend and Platform Software Engineer with 14 years of experience, the last 10 dedicated to DevOps/SRE, distributed systems, and software development. My career evolved from infrastructure administration to building distributed systems in Go (Golang).

Specialist in designing, building, and maintaining scalable, high-performance microservices for the Kyndryl Bridge product, with direct impact on critical global operations. Strong background in Hexagonal Architecture, concurrency (goroutines and channels), service contracts, production resilience, observability, and SRE/DevOps culture.

In production, this work translates into 200M+ automation executions and 16M+ operational insights per month, with a 30% reduction in impact incidents and a 35% gain in global operational productivity.

Based in Hortolândia, SP — Brazil. Languages: native Portuguese and technical English with intermediate reading.
