About me →Client · website and NFC platform
A Berlin UV print shop. One Next.js site replaced their WordPress site and a separate NFC app: services, gallery, enquiries and NFC business cards in one place.
Enquiries roughly quadrupled within three months, mostly from people who found Glastrix themselves.
Direct booking website
A Berlin holiday apartment wanted guests to book direct instead of through Airbnb. Live Smoobu availability, Stripe payments and more than ten languages, without platform fees.
Five repeat guests have booked their next stay here directly, without platform fees.
Own product · tools for rental hosts
Rental hosts on Smoobu keep hitting the same gaps: cleaning handover, tax exports, smart-lock setup. Hostmade is a free toolkit that closes them.
Own product · white-label SaaS
NFC business cards as a ready-made business for print shops: branded sales site, order backend and customer dashboard. Glastrix is the first operator live on it.
Senior Product Manager · Retail Media
Rebuilt a 15-year-old ad system into a self-serve platform on web and app, and moved every advertiser across before the deadline. As interim Domain Lead I led three squads, up to 25 people.
The AI campaign analysis I built runs on 200+ campaigns every night and became the account managers’ daily tool.
