I'm A. Harrison Friedman, an independent builder. I ship small, deterministic data-transformation Actors that charge per successful operation and never invent a number:

• Dataset Cleaner  - dedupe, money/date normalization, PII scrub
• Financial File Normalizer  - bank/broker exports to verified JSON
• Crypto Export Normalizer  - Coinbase/Kraken exports to a verified ledger
• Marketplace Sales Normalizer  - eBay sales reports, verified
• Export Secrets Scanner  - leaked keys/PII found + scrubbed copy
• Export Diff  - exact row-level changes between two exports
• Kindle Clippings Parser  - My Clippings.txt to clean JSON
• Provenance Packet Builder  - SHA-256-signed item provenance

Design rules: no LLM in the conversion path, exact Decimal money, fail-closed verification - unparseable values are flagged, never corrected, and unknown layouts are rejected with a clear error. No bank or exchange account connections, no tax advice.

Feedback and real-world export samples are always welcome.
