I ran a phone store, then a restaurant floor. Today, I'm the engineer at RMH3 Dental Supply, where I built the system the company runs its orders, stock and shipping in, and I keep it running.I ran a phone store, then a restaurant floor. Today, I'm the engineer at RMH3 Dental Supply, where I built and run the ERP the company works in. Mostly TypeScript, Node and Postgres: integrations, data correctness, and the deploys.
Before this, software was something I had to use on a shift — a register, a POS, a count that never matched the shelf. Most of what I build now replaces something someone was doing by hand.

At work · Live · 2026
Everything the company does in a day, in one place. I'm the only engineer on it.
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.
Tools for myself · Live · 2026
What keeps five to ten coding agents on one repo from losing work.
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.
On the side · In progress · 2026
The whole thing on my own, from the phone camera to the split.
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.
