Case studies
Each project below comes with something you can check yourself: a running demo, measured numbers, or handover docs. The first is the company where I spent nearly two years. Work for other kinds of buyers is in the archive at the bottom.
Industrial work
-
Nearly two years inside a robot manufacturer
Sole developer for every internal system at Standard Robots, a Shenzhen AMR maker: BOM and supply chain, CRM, deployment, and a binlog recovery that got back 100% of deleted data. Not their fleet software. Signed CTO letter available on request.
-
Making a dashboard query scan 230× less data
Same 50M-row table, naive vs tuned ClickHouse schema, measured with the DB’s own query_log: 1.9 GiB → ~8 MiB scanned. One-command reproduce, CI-guarded, with a 3-min walkthrough.
-
A machine that refuses to do dangerous things
A machine commanded over MQTT, with a gate layer that classifies every command by the harm it could cause. The test harness runs 11 checks in about a second: nine attempts to make it misbehave, all refused, and two that confirm it can still stop and recover. Those two matter, because a test suite that only checks refusals would pass even if the machine did nothing at all.
Earlier work, other buyers
Work for other kinds of buyers (data extraction, payments, marketing ops, routing) is in the archive.
-
Automation, De-risked
A web form becomes a scored, routed lead
Enrich, score, store and notify: a lead pipeline proven end to end on mock data before any real credential is used. With public code you can run yourself.
-
Systems That Don’t Talk
Managing Google Ads campaigns in plain English
An MCP server that lets Claude pause campaigns, adjust budgets and manage keyword bids, with a mock mode you can demo without credentials.
-
AI for Traditional Business
From chaotic backtracking to clean neighborhood sweeps
A vehicle-routing optimizer that finishes one district before opening the next, because real drivers don’t drive the way shortest-path math says.
-
Systems That Don’t Talk
Doing what the Shopify API can’t, safely
Retroactively linking historical orders to B2B Company Locations, a workflow Shopify’s API doesn’t expose, with automated 2FA and no password sharing.
-
AI for Traditional Business
A phone call becomes a spreadsheet row, automatically
Twilio → transcription → LLM extraction → Google Sheets, with a confidence score that decides when a human needs to look.
Besides these case studies, there’s a shelf of public demos that run without credentials, each with a note on what it does and doesn’t prove. Browse the demo library
