I'm modernizing a UPS mail-piece processing system at Sparq, migrating WinForms workflows to Blazor on Azure and redesigning SQL systems. I also built an MCP integration connecting GitHub Copilot with Azure DevOps to generate Blazor components from work items.

I've designed a Figma-to-Blazor AI pipeline and a multi-agent system that analyzes logs, locates code issues, implements fixes, and opens pull requests. My recent work combines production .NET engineering with MCP, RAG, tool-calling, and agentic automation.

Previously at Tata Consultancy Services and EMIS Health, I led architecture for airline platforms, built .NET Core APIs and Blazor applications, and delivered healthcare document-management systems. Across 12+ years, I've worked with C#, .NET, SQL Server, AWS, Azure, React, Angular, WPF, and microservices.
