Problem
A combat-sports startup needed a fast funnel: a landing for Alpha signups and a platform where athletes find sparring partners instead of hunting Facebook groups.
Solution
I built a conversion landing (LCP < 0.8s, 18% conversion) and a Swipe & Match app with real-time chat, Telegram Mini App, and an events calendar.
Landing 100% CRO — hero, social proof, Alpha signup above the fold
LCP < 0.8s via Server Components and image optimization
Supabase Realtime + RLS for chat and athlete data
Geolocation + Swipe & Match instead of Facebook groups
Telegram Mini App and .ics / Google Calendar export

“5,000 signups in the first month. The landing paid for itself in two weeks — 18% conversion vs the previous 2%.”
Stack and scope
The care agency ran a slow WordPress site with no German version and no form that finished recruitment. Candidates dropped off on calls and emails before an offer existed.
The clinical dietitian had no website — no EBM authority in Google, no online booking. Patients couldn't check calorie needs before a visit.
