Senior Full Stack
& Data Engineer

Building reliable data, reporting & AI systems that scale.

25+ years building production-grade web applications, ETL pipelines, and analytics infrastructure. I design warehouse-ready data systems and scalable reporting environments that eliminate manual work and give leadership trustworthy numbers.

My work spans modern full-stack development (Next.js, React, Node.js), enterprise data engineering, and high-volume BI platforms—including large-scale Metabase deployments. I implement targeted AI automation using AWS Bedrock, RAG architectures, and vector search when it meaningfully improves workflows.

Available for select contract engagements through Concept Cache LLC.
