01 / The brief
A web application for venue discovery and reservation management.
Information about Sarajevo venues was scattered across social media, group chats and phone calls.
Gdje Izlazimo connects discovery, favourites and reservations with dedicated partner and admin tools.
02 / The problem
A fragmented path from venue discovery to confirmed reservation.
- 01
Fragmented discovery
Search and comparison relied on disconnected posts, profiles and messages.
- 02
Too many steps to a table
Availability was checked manually, without a clear reservation flow.
- 03
Operations without a system
Requests, capacity and statuses were not managed in one system.
03 / User experience
From “where should we go?” to a reservation in one flow.
- 01Discover
Search and filters by name, category, location and rating.
- 02Decide
Essential details, opening hours, availability and favourites.
- 03Reserve
Date, time, table type and guest count in one clear flow.
A desktop view for fast venue comparison.
04 / Operating system
One product. Three connected views.
Venues
Profile, availability and reservation request management.
Administration
Central oversight of venues, users and platform activity.
05 / Beneath the interface
Designed as a product. Engineered as a system.
