Client work

Client work · published without attribution

  • Receipts and bank statements — CSV, PDF and photographs — parsed into structured transactions.
  • Automatic transaction matching carrying a 70–100% confidence score, so a human can audit a match before it reaches an accountant.
  • Column mapping that adapts to arbitrary bank statement formats rather than assuming a schema.

ColdDeck

Cold email that reads like you actually looked

  • A polite crawler reads a few pages per site and detects concrete problems, then scores them with a deterministic rule pack rather than a model — so every point traces to the evidence behind it.
  • Drafts a grounded email and waits for a human to approve each one before it sends.
TypeScriptNode.jsPostgreSQL

agentic-ai

AI companions backed by the Claude Agent SDK

  • Each character is a folder of plain files — hand-editable, diffable, reviewable.
  • Agents stop for approval before writing anything to disk.
