What I did

Managed and tested every piece of the experience: Windows client, mobile app, and coordinating server.
Configured the Unity application and assisted with on-site install.
Built the Unity scene to client preference and adjusted mobile and server config per venue.

Constraints

Two-week schedule to understand, adjust, and ship a distributed system spanning desktop, mobile, server, cameras, and sensors.
6-meter wide display with a 30% content cut-off band, camera viewport had to be reshaped to the visible area.
Remote design collaboration for art and lighting, iterating against the client's evolving direction.
Damaged hardware components and unpredictable venue conditions on install day.
Multiple communication protocols (TCP + UDP) between server, Windows app, and mobile clients.

What shipped

Software architecture aligned to the MVC pattern for maintainability across venues.
Camera render viewport reshaped for a multiple-display configuration matching the wall's visible area.
Lighting built with Unity reflection probes and baked lights.
Fail-safe server/client architecture handling both TCP and UDP protocols.
Schedule that flexed to on-site conditions without slipping the install date.
