About Me

I'm an SAP Technical Architect based in Alpharetta, GA with 14+ years of experience across large-scale S/4HANA implementations, migrations, upgrades, and support engagements.

Currently the retained lead technical resource at Savancys on a large-scale S/4HANA engagement for one of North America's largest construction and engineering firms — brought through an employer transition by the client.

I specialize in Clean Core-compliant development — architecting BTP ABAP Cloud applications, CDS Analytical Models, OData V2/V4 APIs, and production Fiori UI5 TypeScript applications. I apply OOP design patterns — Strategy, Factory, Template Method — to turn legacy procedural code into maintainable, testable solutions.

I actively leverage AI-assisted development (Claude Code, GitHub Copilot) to accelerate delivery cycles and validate architecture decisions — and manage all my development work through GitHub using both SAP BAS and VS Code.
