I build reliable .NET backend platforms for finance, energy, retail, and applied AI.
What I'm looking for
I've built production backend platforms for Stellantis Financial Services, J. Global Energy, Safra, and Globo, where correctness, reliability, and domain complexity matter.
At J. Global Energy, I helped replace spreadsheet-driven oil trading and inventory control with a production platform for a US-based team. I also delivered a retail inventory product end-to-end, increasing average customer ticket by 3% and generating R$60K in additional revenue within three months.
My work centers on C#, .NET, API architecture, Domain-Driven Design, CQRS, microservices, event-driven systems, Azure, and AWS. I'm now building agentic systems with the Claude API and looking to apply deep .NET experience alongside AI integration in remote US or European teams.
