Message

At Charter Software, Inc., I contributed to modernizing SPAHRS, a long-running enterprise application, into .NET 10 and ASP.NET Core services with a React.js and TypeScript frontend. I analyzed legacy screens, workflows, validation, and business rules, then translated established interactions into frontend components and API endpoints.

I’ve also modernized legacy and payroll-related applications at EmCentrix, moving functionality from Classic ASP/VB.NET to ASP.NET Core and developing REST APIs. In a separate HubSpot-inspired CRM project, I developed a .NET 8 and Angular platform with contact, lead, and deal workflows.
