🎧 Audio Engineer • 💻 Full-Stack Web Developer • 🎸 Musician
I design digital experiences that unite sound, code, and human insight — from a cloud-based I Ching oracle for curious minds to a high-performance .NET system for real-time analysis.
My mission is to help creators and organizations bring ideas to life through immersive, responsive technology that fuses precision engineering with expressive design.
With decades of experience spanning professional audio engineering, C#/.NET web development, and music production, I thrive on solving technical challenges that demand both logic and artistry.
I’ve engineered for national television, built cloud-based web apps, and created platforms that merge ancient philosophy with modern technology — all unified by a single principle: clarity through precision.
- I Ching Rocks — Building an AI-driven I Ching Oracle and learning hub with a forthcoming membership area for personalized readings.
- Poker Hand Evaluator — A high-performance .NET 8 hand evaluator using optimized algorithms and Dapper for speed.
- Studio & Broadcast Audio — Supporting live event mixing, routing, and system design with Calrec, Yamaha QL/Rivage, Dante networking, and Shure/Sennheiser wireless systems.

“Precision, creativity, and clarity — in code and in sound.”
Whether tuning a console or optimizing a query, I approach every system as an instrument — balancing structure, rhythm, and flow.
