For almost twenty years I've turned half-formed ideas into working products, leading design, code, and teams along the way.
Currently I:
-
Work as Senior Director of Applied AI at
Personio, where I split my time between design and engineering. I shape our product architecture, design tooling and tinker with inference systems, post-training workflows, and evaluation pipelines. My work spans model development, fine-tuning, benchmarking, and UX design while leading Growth and company-wide AI initiatives.
-
I'm also building Succinct, a platform for evaluating and benchmarking LLMs with custom judge models, Fine tuning, inference and model routing. Succinct helps teams measure model quality, compare providers, run post-training experiments, and ship AI that don't waste tokens or money.
Previously I:
-
Scaled Shopify Markets from MVP to the international commerce backbone that lets millions sell globally and in the process changed how Shopify operates.
-
Reimagined checkout, payments, and post-purchase at adidas.
-
Led Applied Machine Learning and
industrial + software design at
Adyen, shipping SOTA fraud detection software and on-device Point of Sale UX in lockstep with hardware.
-
Drove applied consumer psychology and persuasion projects at
Booking.com, helped build their first live-learning ML recommendation models, and designed patterns many e-commerce sites still use today.
My default move is to prototype, translating ambiguity into tangible things you can interact with that rally teams and push decisions forward.
Getting clarity at high velocity.
When I'm not shipping, you'll find me building side projects, racing cars, carving mountain trails on my bike, or chasing powder on a snowboard.
