Message

At GlobalLogic, I modernized a large, multi-tenant platform from .NET Framework 4.8 to .NET 8 and ASP.NET Core, using specification-driven workflows with AI coding agents. I delivered traceable bug fixes, features, and refactors while preserving data-access boundaries and auditability.

I authored claude-code-harness, an open-source harness for reliable AI coding on legacy codebases, and created reusable doctrines, agent skills, and commands adopted by engineering teams. I also integrated LLM APIs for document and image analysis and delivered internal training on Specification-Driven Development.
