Notes from the field.

Working notes on the craft: engineering at scale, the AI-era developer experience, frontend that most teams leave on the table, and whatever else has my attention.

Building SoberMark: twenty public datasets, one record per provider
SoberMark is a national addiction-treatment directory I build and run solo under my LLC. It assembles 10,900+ providers from twenty federal and state data sources, matches the same facility across sources into one record, and serves it through PostGIS and full-text search. I built it to get deep on databases: search, cleaning, combining, and managing data in production.

Building SoloSteady: applied AI where the numbers have to be right
SoloSteady turns twelve months of bank deposits into an income summary for self-employed people applying for a bank-statement mortgage. I build and run it solo under my LLC. I set out to learn applied AI and agentic systems in production. The biggest lesson was where an AI model belongs in a money document, and where it does not.
