Modernization Lead at Greatland Corporation leading AI-native tax software modernization on Azure with Claude Code.

United States

Message

At Greatland Corporation, I lead an AI-native modernization of tax filing software, moving on-premises systems to an Angular front end and .NET Core backend on Azure. I work hands-on with Claude Code and GitHub Copilot across analysis, build, and test, while partnering on architecture decisions that protect filer data and support maintainability.

At Vindex, I built two development teams and an SRE team, and built the Square payments integration for subscriptions, sales, and event entry fees. I also proposed and led a developer experience platform whose Terraform framework stood up 25+ serverless microservices on AWS; later, at FM Global, I owned reliability for an Azure microservices platform serving product APIs through a shared GraphQL layer.
