I help organizations integrate AI into the Microsoft enterprise ecosystem — connecting Azure OpenAI, Azure AI Foundry, and RAG-based solutions into existing .NET backends, Dynamics 365 environments, and Azure cloud infrastructure. My focus: turning AI capabilities into production-ready, secure, and observable systems.

With 8+ years of enterprise experience in the Microsoft stack — including cloud migrations, DevOps automation via IaC (Terraform, Bicep), and complex Dynamics 365 integrations in regulated, DAX-listed environments — I bring the architectural depth that AI projects in the enterprise actually demand: keyless authentication with Managed Identity, centralized AI gateways, cost control, and full observability from day one.
