Personal Software Portfolio

I'm an experienced software developer with a variety of side hobbies including electronics, music and photography. I have experience in desktop and mobile C, C++, Obj-C, C#, Swift, JavaScript and TypeScript development. I created the SchemaCoder database code generator and Elise Graphics library, but have more recently been focusing on spec-driven, AI-assisted creation of applications including audio tools, graphics applications and libraries - all with a focus on careful engineering and thoughtful interfaces.

About this site

Schematrix is a personal portfolio

For years, schematrix.com was the home of SchemaCoder — a commercial .NET data-access code generator. SchemaCoder is now an open-source project on GitHub, and this site has grown into a portfolio for personal software work, technical writing, and ongoing experiments.

Most of what you'll find here are personal Windows desktop applications, audio tools, and graphics utilities. Articles and writing will land here over time.
