Web & product
I built a catalogue of 15 modes you can hear in the browser, plus a 3D Tonnetz showing why two chords sound close.

Claude Code · rules · subagents · hooks
Markets & comparators
I track the sugar-crude spread against a timeline of 6 dated events that explain the jumps.
Data & public sector
I'm turning a folder of scraping and cleaning scripts into a static catalogue anyone can search, preview and use offline.
Python · SQLite · static site, no server
Infrastructure & servers
I connected Claude Code to an OpenMetadata service running over an Oracle and SQL Server warehouse, so ingestion, lineage and server lifecycle are managed as code.
OpenMetadata · Oracle · SQL Server · Python · Docker
Data & public sector
A search tool over service records, built so the right one turns up by content instead of a manual folder hunt.
Python · SQLite · search index
Agents & AI automation
A market monitor where the model has to write a falsifiable prediction before it can be scored — 3 open, 0 resolved, the first ones due January 2027.
Python · GitHub Actions · SQLite
Web & product
I built a store with 16 products, a look builder and checkout using the payment methods people actually use in Peru.
