Software engineer & architect
Robbie
Ribeiro.
Full-stack engineer and architect for C#, .NET, Angular and Azure.
20+ years building scalable, testable software for global clients. Today I architect event-sourced .NET platforms and work AI-first: agents handle scaffolding, refactoring and tests, while I own the architecture and review every change.
