Open House Praha needed a mobile companion for a weekend where people move quickly, compare buildings, and make decisions on the street.
I led the build with a team of six engineers. The work covered the app experience, the festival data model, release coordination, and the practical details that make a high-traffic event app usable when the weekend starts.
The app reached 6,000 downloads in one weekend, held a 5-star average rating, and is still shipping today.
What Shipped
- Festival browsing and building discovery
- A mobile-first experience for visitors on the move
- Firebase-backed data and release workflows
