About

Passionate about crafting exceptional digital experiences

I'm a full-stack software engineer with over 30 years of experience building and maintaining software across desktop, web, cloud, and mobile platforms. My background is grounded in C# and the .NET ecosystem, but I've worked across a wide range of languages and frameworks over the years — adapting as the industry moved from VB6 and ASP.NET Web Forms to Angular, React, and Next.js, and more recently into AI-assisted development with tools like Claude, LangChain, and RAG workflows.

Over the course of my career I've built systems for organizations ranging from Salesforce to hospitals, state government, and small consultancies — including years spent developing Salesforce's flagship marketing automation platform, leading a transportation management system for a logistics carrier, and building a global genome-research platform for Eli Lilly. That range has given me a practical sense of what production software actually needs to hold up over time.

Today I run my own company, where I architect and build full-stack products end-to-end — including Dock-Scheduler and 3PL Marketplace in the logistics space, and Subzero for field service management — while staying comfortable in Agile and SAFe environments. I still enjoy mastering new tools and untangling complex problems as much as I did 30 years ago.
