Professional Summary

I'm a seasoned fullstack and cloud engineer with over 20 years of experience, having worked across a wide range of technologies — from legacy enterprise systems to modern cloud-native architectures.

In recent years, I've been focused on high-impact backend and infrastructure projects involving containerization, Kubernetes (AKS), CI/CD pipelines, and cloud migration strategies. My latest work includes helping refactor and migrate a large-scale financial system from AWS to Azure, in collaboration with international teams and Microsoft engineers.

I value clean architecture, scalability, and simplicity. I'm fluent in English and Portuguese, and I'm currently looking for remote-first opportunities where I can contribute to meaningful systems and help scale backend and cloud infrastructure in fast-moving teams.
