KassenPuls
KassenPuls: a free product I built end to end, from the monitoring engine to the marketing site. It tracks the supplementary contribution (Zusatzbeitrag) of all 92 German statutory health insurers daily and emails members the moment their fund raises it, so they can use their special right to cancel before the deadline passes. I designed and built the app, handle its SEO, and run the Google Ads that bring in sign-ups.
