About

I started in tech support — the kind where someone hands you a machine that doesn't work and expects it to work by the afternoon. That turns out to be good training for software: you learn to reproduce a problem before theorising about it, and you learn that the user's description of the fault is evidence, not diagnosis.

Since 2021 I've been building mobile and web products, mostly in Flutter and React. The work I'm proudest of isn't the prettiest: it's a buy-now-pay-later app whose crash rate I helped cut by more than 40% while it was live for hundreds of thousands of people, and a product I moved off low-code without losing a single feature.

Through my own company, Codelyn, I spent a year contracting on the kind of work that doesn't fit in a browser tab — pairing NFC card readers to a wallet that settles offline, shutting industrial fire pumps down from a phone through an ESP module, routing windscreen technicians between jobs in the UK. Software that has to agree with a physical object is a different discipline, and I like it.

Right now I'm at Tripleblue working on AI products — their knowledge agent and AI Notes, plus the note-taking mobile app and the German DMS counterpart. The interesting problem there isn't the model. It's everything around it: what the product does when the answer is wrong, and how a user can tell.

I gravitate toward systems where correctness has consequences — payments, hardware, background processing, anything where "mostly working" is a synonym for broken. I finished a BSc in Computer Science at Akademia in 2025 and I'm now reading for a BSc Honours at the University of Pretoria, moving toward digital forensics and cyber security. Based in Pretoria, South Africa.

Freelance clients

Through Codelyn, 2025–2026. Short write-ups — the full case studies in Work go deeper.

  • Firebrain (Softechware)

    Mobile app, web app and backend for an industrial fire-pump system. Technicians shut pumps down from the app via an ESP module on the hardware, and WhatsApp alerts route to whoever is on call.

    • Flutter
    • ESP modules
    • IoT integration
    • WhatsApp API
    • Firebase
    • Node.js

  • Batsamayi

    A cashless payments app built on physical NFC cards. I paired the card hardware to the Flutter app and set up wallets that hold and settle value on the device, so a transaction does not need connectivity to complete.

    • Flutter
    • NFC
    • Payments
    • Dart

  • Fix Glass (UK)

    Field-service app for windscreen technicians. I improved the existing Flutter app and added Maps with turn-by-turn navigation, so technicians route between jobs from inside the app rather than switching to another one.

    • Flutter
    • Maps & navigation
    • iOS
    • Android

  • Bowlsmaster (Fairtree)

    Feature work and improvements on their Flutter application.

    • Flutter
    • Dart
