Software Engineer & Game Developer

Who I am

About Me

I'm a Software Engineer from Brazil with over 10 years of professional experience across operations, full-stack development, and cloud infrastructure. My work spans building large-scale Java application fleets, cloud control planes, SaaS onboarding pipelines, and infrastructure automation using Azure, Docker, and Kubernetes.

I've worked with companies like InComm, Haivision, and TOTVS — one of Brazil's largest ERP companies — developing everything from e-commerce integrations and bank services to license management systems and DevOps tooling.

Beyond my day job, I'm an indie game developer. I build and ship my own games and tools using Unity, Flutter, and Azure Functions — always experimenting with new ideas and technologies.
