For purpose-driven businesses

Systems you can check.

I build complex systems that feel simple to use: AI assistants that show their sources and wait for your yes, reports that say what’s actually happening, and fixes for tools that quietly disagree.

A sentence or two is enough. I reply within one working day, and I won’t chase you.

Checking a draft

A brand’s post

Approved, word for word

The draft

Tap a sentence, or move to it with the keyboard, to see why it got its mark.

Nothing goes out until you approve this exact version.

What people ask me to build or fix.

You don’t need a specification. If it sounds like one of these, it’s worth a few sentences.

  • A report that says what’s actually happening

    Built from what customers do: what they search for, what they read, where they came from, what they open next.

  • Two systems that finally agree

    Integrations between your store, email platform and other tools, and fixes where they quietly disagree.

    See an example →
  • A tool that helps customers choose

    Finders, calculators and pages that help people pick the right thing, built from your own product information.

    See an example →
  • Someone to find out why

    An investigation of what’s broken between your systems, with each failure reproduced before it’s reported.

  • Something that drafts, and waits for me

    Assistants that draft from approved material, with every consequential action waiting for a named person’s approval.

  • The thing you’ve been describing for a year

    A first version of the tool you keep sketching, scoped tightly enough to test with real use.

Built with Python and TypeScript, on the platforms you already use, such as Shopify and Klaviyo.

Short versions here; the fuller record, with dates and method, is on each project page. Most clients aren’t named, and I only give dates I can verify.

Sofema Aviation, my family’s company

A Knowledge Hub with its own analytics dashboard.

I built a Knowledge Hub that explains aviation regulations in plain English, and gave it a dashboard of its own: what readers search for, which pages they read, and which courses they open next. Alongside it, a Course Finder and a Training ROI Calculator help visitors choose training.

The Sofema Knowledge Hub home page: a search box with example searches, and subjects to browse.The hub’s own dashboard, blurred.
Left: the public hub. Right: the hub’s own dashboard, blurred until Sofema’s permission to show it is recorded. Its 7-day view, captured on 28 October 2026, showed 502 visits, 560 page views, 30 searches and 15 course and package opens.

As it stood on 17 October 2026, the hub and both tools were public on Sofema’s site, and the dashboard was running. A click is not an enquiry, and effects on adoption, bookings and revenue haven’t been measured.

A founder-led wellness brand

Jessica: an email assistant with tools.

I built Jessica, an assistant that drafts social posts, emails and page changes from her approved product and health wording, on an unpublished copy of her Shopify site. It also turns requests into proposals and prepares short social videos in Buffer for her to review. She reads each draft, edits it if she wants, and approves or rejects that exact version. Only then is it sent, and recorded.

In use since September 2026. Every piece so far has been approved by her before it was sent. Time saved hasn’t been measured yet.

A private engagement

Six failures between a store, its email platform and connected tools.

I investigated the business’s store, email platform and connected tools, and reproduced each failure before reporting it. The largest: the store believed 5,490 customers could be emailed, while the email platform could reach about 150. Neither system flagged it.

Revenue impact wasn’t measured. The business isn’t named.
