Data & AI engineer. I also build too much.

Fifteen years in data engineering and backend systems — pipelines, warehouses, and the unglamorous plumbing that has to be right. These days I build AI-native: agentic systems, retrieval-augmented generation, and the workflows that ship them.

The proof is open. Glasshouse is an agentic Claude Code skill that audits any site against GDPR and drafts the complaint. The jukebox turns a text prompt into a finished track. The rest of the site is writing on how the pieces fit, and small interactive tools when an idea wants a sandbox instead of a paragraph.

[S.01]§ What I'm working on
01
Glasshouse
Agentic AI engineering in the open — a Claude Code skill that runs a full GDPR + ePrivacy audit (consent, pre-consent tracking, cross-border transfers, security headers) and drafts the complaint for the right authority. MIT-licensed, nine EU data protection authorities seeded. Also runs as a private scan service.
02
The jukebox
An AI generation product: a text prompt becomes a finished track in ~30 seconds, queued and rendered on demand, with a live audio visualizer and a shared public playlist. The interesting part is the pipeline behind the playfulness.
03
Writing + tooling
Cornerstone deep dives on data & AI engineering — pipelines with dlt and DuckDB, column-level lineage, RAG backends, SQL window functions — plus interactive explainers when an idea wants a sandbox instead of a paragraph.
[S.02]§ How I work

Every project on this site was built AI-natively — from first prompt to deployment. Claude Code is my default development environment. I design through conversation and iterate in real time.

It isn't really about writing code faster. It's about thinking in systems, sketching in language, and letting ideas materialize without the friction of boilerplate.
