What I do

AI in production, apps in the stores, sites people own

Mobile apps in Flutter

My own apps, built with Flutter and Firebase and shipped to the stores. MealMate is still live.

MealMate: Protein Meal Plan

MLOps and AI platforms

My day job: the platform at Sixt that gets models out of notebooks and into production.

  1. ML platform architecture

    the training, deployment and monitoring path a team uses daily, not a single pipeline that works once

  2. Prototype to production

    taking a model that runs on a laptop and making it something an on-call engineer can be woken up for

  3. AI features inside a product that already exists

    scoped so the useful part ships before the budget is gone

  4. Direction for a team already building it

    architecture, tooling, and the handful of decisions that are expensive to reverse

Websites and brand identity

Identity, design and build for people whose name is the business. When we are done, you own all of it.

Technical leadership

I lead a team of ML and MLOps engineers, and help other teams with the decisions that are expensive to undo.

Client websites

Websites for people whose name is the business

Freelance, end to end: brand identity and logo through to a running site with a CMS, a blog and a newsletter behind it, handed over so you can keep changing it without me.

  • Brand & corporate design

    Logo, palette, type and motion: the identity before the site.

  • A site you own

    Pages, blog and newsletter in a CMS with your name on it.

  • Guardrails, not handcuffs

    Security, speed and correctness, checked automatically.

  • Handover that survives me

    A codebase where you can change copy and colour without me.
