What I'm looking for

I'm looking to build and modernize enterprise systems, lead Agile engineering teams, and apply cloud, architecture, DevOps, and growing AI skills to meaningful products.

I've delivered cloud-native microservices, enterprise architecture, and full-stack applications for Authority Partners, Cyclomedia R&D, ASML through ALTEN Nederland, and ABCZ. My work spans C#/.NET, ASP.NET, Azure, AWS, SQL Server, PostgreSQL, React, and DevOps automation.

I'm currently building a RAG chatbot using MCP, vector search, and real-time genealogy data for Brazilian genealogical registration regulations. I also lead Agile teams, design systems with ArchiMate and C4, and modernize high-scale legacy platforms.
