Field work.

Most of my client work starts the same way: build the thing first, then talk. This page is the ledger. Live demos built to win specific briefs, each computing something real, and case studies from client work, anonymized. No mockups: every demo below is live.

A card matcher that refuses to guess

for a trading-card arbitrage platform (US) · completed June 2026

Cross-marketplace listing matcher against a live product catalog. The rule that won the job: abstain rather than mismatch. The pipeline commits a match only when it is sure, and routes everything else to a review queue instead of guessing.

  • 99.4% precision held on the priority stratum, re-verified across catalog re-scores
  • Backlog drain closed 2,481 listings clean, zero wrong-id commits
  • Read-only against production; every write stayed with the client's engineer

Making a news site legible to answer engines

for a Singapore business-news publisher · shipped to production June 2026

Full GEO upgrade of a live WordPress news site: speakable and 5W1H structured data on every article, a machine-readable citation layer, and a site-wide heading-hierarchy migration. Shipped against a paywalled production theme with automated schema verification on every template. The client then kept me on to measure the results in live AI answers.

  • Speaker, 5W1H and citation schema live on every article template
  • Automated schema validation wired into the delivery pipeline
  • Shipped on production WordPress (TagDiv) without breaking the paywall
  • Articles now documented in AI answers on Perplexity, Google AI Mode and Overviews, and ChatGPT

17 gates for a fine-tuning corpus

for a conversational-AI product team · in progress

Quality system for a supervised fine-tuning dataset: 17 automated gates covering schema, voice fingerprint, grounding, brand and distribution checks, plus a cross-batch drift layer and an LLM-judge review fleet. Rebuilt the weakest gate's classifier mid-engagement so it catches the shapes that actually occur.

  • 3,109-entry corpus scanned, drift-mapped and calibrated
  • Classifier catch rate raised from 16.4% to 59.5% after the rebuild
  • Cross-batch drift gate compares each batch against a rolling window
  • Every flag lands in a per-batch findings CSV, fully traceable

A water-contaminant atlas that runs offline

for an environmental data consultancy · atlas delivered June 2026

PFAS pipeline across public regulatory sources (US UCMR5, British Columbia EMS, California SDWIS) with per-row provenance: every value in the output traces back to the exact source row it came from. Censored lab data handled properly with Kaplan-Meier statistics instead of naive substitution. Delivered as an offline single-file atlas by design, so there is no public URL.

  • Three regulatory sources unified into one provenance-tracked dataset
  • Detection-limit (censored) data gets real survival statistics, not guesses
  • Ships as one HTML file the client's team opens without a server
  • A 45-check build verifier caught a silent regression before the client ever saw it

Seven statement formats, one dashboard

for an insurance brokerage · completed April 2026

Commission statements from seven insurance providers, each in its own format, reconciled into one Excel dashboard. Delivered not as a script but as Claude skills with append-only guardrails, so the client reruns the whole consolidation himself with no developer in the loop.

  • 7 provider formats ingested, normalized and reconciled
  • Append-only guardrails: reruns can add, never silently overwrite
  • Client operates it himself via Claude skills
“Excellent work and went above and beyond in terms of service and time.”
