Digital operations + AI automation

I build the systems that take repetitive ops off people. Ecommerce is how I learned to run them.

How we work

Name the leak. Ship the job. Connect the desk if it holds.

  1. 01

    Name the leak.

    One repetitive job, or a desk that does not talk to itself.

  2. 02

    Ship that job.

    A person still approves spend, outbound messages, or record changes.

  3. 03

    Connect the desk only if the job holds.

    You keep the licences.

STACK

What I build with

The stack in daily rotation, and the tools I recommend.

Agents

  • Claude

    The model I write agents and ops software against.

  • Cursor

    Where the software gets written.

  • Vercel AI SDK

    Model-agnostic calls in production apps.

Build

  • Next.js

    The app layer for every JS Labs system on this site.

  • Supabase

    Postgres and auth for the agents that need state.

  • Vercel

    Hosting, cron, and preview URLs.

Ops

  • Amazon SP-API

    Live listing state in and corrections back out.

  • PostHog

    Typed events so a funnel is readable the week it ships.

Operator notes

Short write-ups when something ships. What broke, what it cost, what runs now. No schedule, no selling.

Get the notes

Send the job you want gone.

Say what you sell, which channels you are on, and what is stuck. You get a path back, or a straight no.
