12 things & counting
I'm Nico. I lead a support team at Automattic and make small, sharp, occasionally silly things outside work: apps, developer tools, essays, and independent websites. These are the projects I care about right now.

A free, open-source combat console for D&D 5e Game Masters.

Reusable skills for coding agents, built from workflows I use and shared for others to adapt.

Essays on work, software, and the web, written slowly and with care.

Repeatable, annotated UI screenshots from declarative recipes. No code per shot.

Roll dice in JavaScript or TypeScript with a formula parser and a single roll() function backed by a CSPRNG with modulo-bias rejection.

A decade of WordPress and WooCommerce notes, preserved as a reference.
