I've worked at Stone Payments, Banco Iti and Itaú Unibanco — banks, payment providers and financial services.

I also mentor people building an international tech career.
And I write about SRE, cloud and career.

About me

I'm a Site Reliability Engineer focused on the reliability, observability and performance of production systems. I've worked on high-traffic customer-facing platforms, defining SLOs/SLIs, bringing MTTR down and building observability end to end.

I also create content about SRE/DevOps careers and mentor people who want to grow in the field, including those aiming at the international market.
