I build scalable .NET and Azure systems, from enterprise microservices to privacy-first RAG platforms.
PortugalWhat I'm looking for
At Whitestar, I build enterprise-scale real-estate asset-management software, designing .NET Core and Azure microservices, asynchronous integrations, and cloud-native services. I've improved performance with SQL Server optimization and Redis caching while resolving distributed-system concurrency challenges.
I'm also building a legal-tech SaaS RAG pipeline using .NET 8, PostgreSQL/pgvector, React, Docker, and CQRS, with privacy-first local LLM inference and GDPR/LGPD-aware architecture. Across 16+ years, I've delivered enterprise integrations and high-performance backend systems across finance, energy, government, telecommunications, healthcare, and industrial production.
