UX + Tech + Bio + AI — blog, portfolio, experiments

Sydney until 2024

I’m Jan, a product designer and full-stack dev. I’m currently doing biotech and AI engineer experiments, specifically for tackling complex data engineering problems.

Day-to-day, I’m a product and data engineer working on a phage therapy clinical process trial at PhageAustralia, at the Westmead Institute for Medical Research.

On the side, I’m a co-founder of Phage Directory, a platform for crowdsourcing bacteriophages for patients dying from drug-resistant infections.

I also like:

  • Building silly sites (like, which is a wrapper around Notion, Vercel, and Cloudflare, and powers this and dozens other sites!);
  • Run community events and conferences like Evergreen Phage Meeting (a weeklong gathering of 200+ of the best phage microbiologists from around the world in the woods of Olympia, WA) and AI + UX in Sydney (a tiny get-together of AI engineers)


In a previous life, I’ve been lucky to have the opportunity to build cool projects for many fun clients — like the design and build the refresh for Gas South, design the entire Home Depot Workshops flow, co-create with the L’Oreal hair color team in New York an internal system for aligning their hundreds of hair color products with what will fit a customer, and so on. Agency work is always full of surprises, and you learn a ton along the way.

I don’t do much freelancing anymore, but I’m curious to take on specialized AI engineering projects. Reach out at if you need an AI-centric project built.
