Principal Full-Stack
& Data Engineer

Building reliable data, reporting & AI systems that scale.

Principal Full-Stack & Data Platform Engineer with 25+ years building production application, data, and analytics systems. I design and build end-to-end operational platforms — from application layer through data pipelines and reporting — replacing manual workflows with scalable systems that support operations, finance, and leadership decision-making.

My work spans modern full-stack development (Next.js, React, Node.js), large-scale ETL pipelines, warehouse-first analytics environments, high-volume BI platforms including large-scale Metabase deployments, and applied AI/LLM integrations and RAG architectures.

Available for select contract engagements through Concept Cache LLC.
