Case study · Yourny Travel & Leisure
A travel app where groups decide and book together.
Yourny brings trip planning, hotel search, group decisions and booking into one product. I built the mobile app, backend and technical operations as one connected system.
- 01 One app across platforms
- 02 From planning to booking
- 03 App, backend and operations
01 / Development snapshot
The product flow in the mobile app.
These screens document an earlier design phase of a product that continues to evolve.
02 / Product and journey
Many travellers. One shared booking state.
Yourny keeps preferences, favourites, availability and payments aligned throughout the group journey.
- Responsibility
- Full-stack development and technical architecture
- Product
- Group travel from planning to booking
- Data
- More than 3 million hotel records
- System
- Mobile app, backend, admin and infrastructure
- 01
Set up the trip
Capture destination, dates, rooms, budgets and amenity preferences.
- 02
Invite the group
Connect travellers by code and follow the planning status together.
- 03
Explore hotels
Discover available properties, rate them and build personal shortlists.
- 04
Decide and book
Combine group preferences, review conditions and complete payment.
03 / System
The complexity sits between the screens.
The Flutter app talks to a Serverpod backend. PostgreSQL stores product and hotel data. Docker, migrations, monitoring and automated deployments keep the system manageable in production.

Payments
Mollie checkout plus status, refund and interruption cases in the booking flow.
Login & messages
Firebase for sign-in, push messages and configuration; Sentry for error monitoring.
Destinations & maps
Mapbox for destinations and location-based features in trip planning.
04 / Technical ownership
What I owned at Yourny.
My work covered the product logic as well as the running system. App, backend and operations were designed together rather than in isolation.
01
Product logic
Turn decisions into clear workflows.
Group planning, hotel selection and booking became clear states and dependable workflows.
- State model
- Booking logic
02
Delivery
Build the app and backend as one system.
The Flutter app, Serverpod backend, data model and external services work together directly.
- App & admin
- API & data model
03
Operations
Keep the product dependable in production.
Migrations, monitoring and deployments matter just as much as booking and payment failure cases.
- Monitoring
- Deployments
