Portfolio Lab

Proof-of-work for analytics, AI, BI, and AWS decision systems.

Decision Layer Analytics is my personal portfolio and applied analytics lab. It is structured like a consulting practice to show how I frame business problems, design systems, and communicate outcomes. I am not currently taking consulting clients, but may open limited advisory or project-based work in the future.
