SOFTWARE DEVELOPER · WEB · SYSTEMS · INTEGRATIONS

I write software for businesses, and for fun. For businesses: web apps, booking and ordering systems, and the integrations that keep stock, invoices and customers in sync.

STAGES

Some for clients, the rest for fun.

Work is the client side. The rest are the things I enjoy, turned into code: my photographs and film looks, the rally stages I follow, and the F1 data I check after qualifying. Each one runs in your browser and comes with a write-up of how it works.

SERVICES

What I Build

00

Web applications

Software with real logic behind the interface: booking flows, calculators, dashboards and customer portals. Built to be fast on a phone with one bar of signal.

  • React, Next.js, TypeScript
  • Node and NestJS APIs
  • SQL databases
  • Tested on real devices
00

Business systems

For businesses outgrowing spreadsheets. Odoo set up around how you actually work, with custom modules where it falls short, so stock, invoices and customers live in one place.

  • Odoo setup and custom modules
  • CRM, inventory, invoicing
  • n8n and API automation
  • Migrating data out of spreadsheets
00

Websites

WIX PARTNER

When the owner needs to edit it themselves. Built properly in Wix Studio, with Velo code for the parts a template can't do, then handed over with a short video.

  • Custom Wix Studio design
  • Online shop or bookings
  • Velo code for the tricky bits
  • You can edit it yourself

HOW IT GOES

Two to four weeks, start to finish.

You'll always know what's happening and what it costs. No surprise invoices, and nothing goes live until you've seen it on your own phone.

  1. 01
    Day 1 · 30 minutes · free

    A call about your business

    Not about websites yet. Who your customers are, what they ask you on the phone every day, and what the site has to do so they stop needing to ask.

  2. 02
    Week 1

    A design you can tap through

    A clickable prototype you open on your own phone. Change your mind as often as you like at this stage, while changes are still cheap.

  3. 03
    Weeks 2 to 3

    The build

    You get a private link that updates as I work, so you can check progress any day without having to ask for an update.

  4. 04
    Launch day

    Live, and handed over

    Domain, email, Google Business profile and analytics set up. Plus a short screen recording that shows you how to change prices, photos and opening hours yourself.

  5. 05
    After that

    Still on WhatsApp

    Something looks off, or you want a page for the winter specials: send a message. Most small fixes are done the same day.
