Microservices, event-driven systems & scalable infra

About

Golang developer and undergraduate in Computer Science at ICMC (USP).

I'm currently a Golang Software Engineer at Orasis Holding, focusing on designing and building scalable, high-performance software for pricing solutions with a microservices architecture in an event-driven distributed environment and SQL databases, extensively applying practices on high-performance concurrent programming, backend systems integration and RESTful APIs development.

I have hands-on experience with open source observability (Grafana, OpenTelemetry, Loki), structured logging with Uber Zap, and DevOps pipelines for delivery and automation.
