The company sold on six websites using six different tools that never agreed. I built the one system that runs it all, about 500 orders a day.One system for orders, inventory, repricing, shipping, service and books across six sales channels, built from scratch, about 500 orders a day.

I use AI helpers to write much of the code, like a chef running a fast kitchen. This is the system of rules and checks that keeps the plates right.How I use AI coding agents at scale without vibe-coding, auto-loading rules, hooks that block the dangerous operations, and review triggered by consequence.

A filing cabinet for my own notes, mail and messages that an AI assistant maintains for me. It proposes what needs doing next; I approve it. Everything stays on my Mac.A plain-markdown vault an AI librarian keeps for me — 738,000 messages indexed locally, nothing filed without my approval, no cloud.

Photograph the dinner receipt, say who ate what, and it tells everyone what they owe. It checks its own answer against the receipt's printed total and won't show a split that doesn't match.Photograph a receipt, tap who had what, get the split. Runs on your phone with no server, and refuses to show a split that doesn't add up.

Ten of us taught robots to re-test a business app every night, after testing it by hand first, which is how we found the bugs the robots would've missed.Two sprints on the CYDEO SDET program — fourteen user stories tested by hand against an ERP, then a Cucumber and Selenium suite against a cloud app.

A game I built in high school using drag-and-drop coding blocks. It has a shop, upgrades, a boss, and a teleport ability, all made without the normal tools programmers use to keep code organised.A space shooter built in block code in high school. 790 lines, an economy, and a boss fight, with no arrays or classes available.

Like Wordle, but with a bouncing ball. One puzzle a day: work out which pocket it ends up in. Guess wrong and it shows you one more bounce.A daily puzzle. A ball bounces three times and drops into a pocket; you guess which one. Every miss shows you one more bounce.

Six parts of the ERP with write-ups of their own. They are not separate projects — they are the pieces that made the whole thing work.
Prices used to be a spreadsheet someone updated every morning. Now a robot checks every product once a minute, and knows better than to start a price war.Replaced a morning pricing spreadsheet with an engine that reprices every minute, with cooldowns, floors, and a rule to never chase the lowest price.
Six websites, each with its own version of the truth about our 32,000 products. One catalog, owned by people, that none of them is allowed to overwrite.Order intake and listing sync for six channels, with the identity rules that keep 49,000 marketplace listings from ever overwriting the product catalog.
A nightly job decides which products are worth counting and reordering. It had been calling nearly everything important, which is the same as calling nothing important.A nightly classifier ranked all 27,215 products and made 1,979 of them class A. Ranking only what sells turned a fake Pareto into a real one.
Every box needs a label and a slip, printed on machines in a warehouse nobody logs into. This is what prints them, checks they came out, and repairs itself when an update goes bad.A thermal-label pipeline and a self-updating Windows print fleet — predicted widths, verified feeds, and an update that rolls itself back.
The sales system and the accounting books have to agree to the penny. This is the connection that keeps them agreeing, and the logbook that ended the false alarms.A two-way QuickBooks Desktop integration over the Web Connector, plus a claims ledger so a finance discrepancy is refuted once, not rediscovered monthly.
The system itself must stay private, but the useful parts don't have to. Nine pieces pulled out and scrubbed clean — real warehouse code, public and readable.Nine self-contained pieces of the ERP, lifted out and sanitized — barcode parsing, thermal-print layout, a self-updating device agent, invoice parsers.
