About

Founder & engineer @ Butterfly Design. Over 20 years turning legacy software into modern platforms — without stopping the business. My specialty is the kind of project most developers avoid: old VB6 ERPs, undocumented systems, critical software nobody wants to touch. I do software forensics, reconstruct buried business logic, and migrate it to clean Flutter + .NET architecture. One developer. No big bang. No downtime. Recent work: 20-year-old ERP → 36 Flutter screens + AI assistant, in 4 months. Stack: Flutter · .NET Clean Architecture · SQL Server · ASP.NET Core · Docker Also building: MusicBox.Digital (AI-enhanced music streaming) Let's connect if you're dealing with legacy software that works — but is holding you back.
