CSS Winner —
A gym timetable with live spots and a waitlist that moves. Recognised for speed on mobile at a time when nobody was doing it.

“Mobile performance treated as a feature, not an afterthought.”
The build that won this is not a showreel piece. It is a working gym site doing a job every day: live spots and a waitlist that moves. That is the part a jury noticed, and the part an owner feels in the first week.
If you run something similar, the same thinking transfers. Builds like this start from €700 and go live in 7–10 days, with the price agreed before we start and the delivery date in writing.
