Based in North Rhine-Westphalia · CET

Hi, I'mJeremy.

I design and build products for the web. Right now mostly on BusinessCodex and OnboardOS — with Next.js, Supabase, Stripe and a bit of AI.

About

A little about me.

I've been working on web products for years — as a founder, developer and designer in one. My day is split fairly evenly between code, product work and small design decisions.

Right now I run BusinessCodex (a web agency in NRW, Germany) and OnboardOS (a restaurant SaaS for the DACH market). I built both end-to-end, from the first line of code to running them in production.

What I enjoy: small teams, clean design, code that holds up — and tools that actually get used in everyday life.
