Available to hire
Hi, I’m Marcos Orsi Ragazzo do Prado. I’m a seasoned SRE/DevOps and Kafka specialist with 16+ years in IT. I’m passionate about deploying, scaling, and automating Apache Kafka and Confluent clusters to support high-throughput, multi-tenant environments.
I’ve led multi-cloud migrations (AWS, Azure, OCI), built robust CI/CD pipelines, and designed reliable, scalable architectures. I enjoy collaborating with development and security teams to deliver resilient, production-grade systems.
