I’m a Senior/Lead Unity Engineer with 17+ years of professional experience, specializing in C#, scalable architecture, cross-platform development, tooling, and performance. I’ve worked with teams and companies across Brazil, Germany, and the US, including Instituto Alfa e Beto, Goodgame Studios, and Ello Technology, contributing to educational products, large-scale live-service games, and production applications. Today, I also develop and publish games through Or Games, shipping across PlayStation, Steam, Epic Games, iOS, and Android. My strength is taking ownership beyond individual features. I design modular architectures, reusable Unity systems and packages, backend integrations, CI/CD pipelines, and platform abstractions that keep projects maintainable as they grow. I’m particularly suited to projects that need an experienced engineer who can quickly understand an existing codebase, solve complex technical problems, improve architecture, and reliably take features or complete systems from concept to production.…I’m a Senior/Lead Unity Engineer with 17+ years of professional experience, specializing in C#, scalable architecture, cross-platform development, tooling, and performance.
