Filmo acá is a mobile app that helps cinematographers, photographers, and small production teams find and book locations — with all the details they actually need to decide, in one place. Real users validated the architecture through card sorting: 90% grouped categories the same way. 100% of testers searched from the home screen without help. The booking flow went from confusing to 5 simple steps. Three things I'm proud of: ✓ Real users validated the information architecture through card sorting. 90% grouped categories the same way — that's not a guess, that's a pattern. ✓ 100% of testers could search from the home screen without help. That's the kind of clarity you design for. ✓ The booking flow went from "how do I do this?" to 5 simple steps. Log in, search, filter, check availability, book.
