About

I am a software engineer and technology founder with 20+ years of experience building distributed systems, developer platforms and high-load services.

My work focuses on:

• AI infrastructure
• distributed systems
• knowledge systems
• developer tooling
• the .NET ecosystem

I build real production systems around AI instead of demos.

Currently I run Managed Code, a boutique engineering studio where we design and build complex software systems, AI platforms and developer tools.
