Building systems,
data platforms & tools.

Principal-level engineering for production systems, warehouse-first analytics, and developer tools that ship.

I build end-to-end application and data platforms that replace brittle manual workflows with systems people can actually rely on. My work spans full-stack applications, ETL pipelines, warehouse-first analytics, reporting platforms, and the operational glue that keeps recruiting, finance, and leadership teams aligned.

Alongside enterprise platform work, I design and ship independent developer tools under the Gnome ecosystem, including SQL Gnome, Diff Gnome, and Hire Gnome. The common thread is practical software for real-world data and operations problems.

I use AI-assisted development workflows, including Codex and Claude Code, as a force multiplier for prototyping and delivery while keeping architecture, maintainability, and production quality firmly under human control.

Available for select contract engagements through Concept Cache LLC.
