espresso the cat

I build with AI. She reviews it.

Tools, automations and maths art, built AI-first, checked by a black cat.

Five things on the go

  1. Fractals on the GPU

    Lets Claude render maths art on my graphics card. The swirl up top is one, live.

    Running

  2. Cortana

    My setup around Claude Code: project notes, a memory, to-dos and a dashboard.

    Daily use

  3. A sourcing tool for a recruiter

    Finds engineers from their public work. Built with a friend for a client, so private.

    Private

  4. A stats site, rebuilt

    A new frontend for a League of Legends stats site.

    In progress

  5. Espresso learns to dance

    My dance, her body, via a video model. Watch it below.

    Done

Rendered on one graphics card

A symmetrical blue fractal of swirling bands around two bright discs
The three-body problem. Each pixel is a starting spot for the third body; the colour is how long it lasts before its sixth close pass.
A glowing orange and teal cloud shape on dark blue, mirrored left to right
A nebulabrot, 33 billion samples, with the card kept under 72°C.
The Mandelbrot set above a chart of rabbit populations, each split in the chart lining up under one of the set's bulbs
Rabbit populations and the Mandelbrot set turn out to be the same maths.

How I build

Ex-teacher, ex-esports coach. Now I direct AI to write software.

  1. I decide, Claude types

    Claude Code writes most of it. I pick what to build and test it.

  2. Agents split the big jobs

    A planner, a few builders, then Abby the bug reviewer.

  3. Nothing gets forgotten

    Cortana keeps notes and decisions, so no session starts from zero.

  4. Local models do the reading

    A small model on my own graphics card reads long logs first.

Espresso

Black shorthair, yellow-green eyes, one white tuft. Head of quality control.

She sits on the stairs and watches everything get built. The colour of this site is her eyes.

Espresso, dancing. She did not consent.
