Pragmatic Systems Architecture

I’m a Senior Software Engineer transitioning to Principal, with 40 years of programming experience and 15 years building production systems. I write about pragmatic architecture, polyglot programming, and solving real problems with appropriate solutions.

What I Write About

• Pragmatic Design: Starting simple, adding complexity only when needed
• Polyglot Solutions: Using the right tool for the problem (Rust, Elixir, Go, Java)
• AI Architecture: Event-driven systems and AI-human collaboration
• Cloud-Native Patterns: GCP-certified with production experience across AWS, Azure, GCP

Current Projects

Partnership Pinochle Scorer - Rust backend with clean architecture, demonstrating ports and adapters pattern and domain-driven design.

Grimoire AI Platform - Event-driven AI agent platform using Elixir/Phoenix, Neo4j, and Firestore. Architecture design phase.
