Message

At CARET, I build C# microservices and .NET Core MVPs for GenAI discovery initiatives, integrating Azure OpenAI, Pinecone-based RAG, enterprise data sources, and secure AI workflows. My work reduced project kickoff times by 35%, improved automated response accuracy by 42%, and earned approval for three AI-driven product features.

I've also delivered high-throughput backend, data pipeline, cloud, and AI integration work at Walmart, Service Corporation International, Halliburton, and Apple. I focus on turning complex requirements into production-ready prototypes using C#, .NET, Azure, AWS, Kubernetes, Terraform, SQL, microservices, and observability tooling.
