Software developer

Apps and systems that stay out of your way.

I build simple, dependable software: my own apps for people, and websites, portals and payment-ready platforms for schools and foundations.

Current project

S Wallet

Android · coming to Google Play
S Wallet: the app icon, the line “Super Simple Smart”, and two phone screens showing quick add and the spending chart

A personal money tracker that opens instantly and asks for nothing.

Pick a currency, type an amount, done. Wallets, debts with due dates, payment reminders, charts and home-screen widgets, in 29 languages. No accounts, no ads, and your records stay on your phone.

How I build

  1. Data belongs to its owner.

    My apps keep your records on your own device. The systems I build for organisations leave the data in the organisation's hands, not mine.

  2. No ads, ever.

    Software is paid for by the people and organisations that use it, never by showing you someone else's product.

  3. Simple is a feature.

    Fast to open, quick to use, few settings. If something doesn't earn its place, it goes.
