Software Architect · Durango, Colorado

Fifteen-plus years building and owning production systems end to end — requirements, architecture, deployment, production support, iteration. Deep in .NET, Azure, Python, and SQL, with systems built to PCI-compliant standards. I build RAG and document-intelligence systems, agentic AI workflows, and geospatial platforms — and use AI tooling daily to rethink how engineering gets done.

The projects below are how I demonstrate that, not just claim it: each one islive, open source, and breakable on purpose — with the architecture documented down to the decision history.

Proof of work

What I bring

• Full-stack production ownership. End-to-end product ownership — requirements, architecture, shipping, iteration. Production APIs in .NET and Python; Azure infrastructure; observability with structured logging and correlation IDs as defaults.
• Data pipelines & ML integration. 20+ production ETL/ELT pipelines with real-time integrations; document processing at scale; RAG architecture, embeddings, and agentic AI workflows; event-driven distributed systems.
• Geospatial & environmental systems. Satellite-data pipelines (Sentinel, Landsat, STAC), geospatial ML with spatial cross-validation, and map-based decision-support UX — built on a decade of GIS engineering and an environmental-studies foundation.
• Hands-on technical leadership. Leads through implementation, not just design docs; mentors on system design, code quality, and testing discipline; champions AI-assisted engineering that accelerates without sacrificing quality.
