Seattle Monorail

The Monorail was still using payment booths from the World's Fair of 1962, and these couldn't handle the volume of riders expected for Kraken hockey games at the renovated Climate Pledge Arena. I designed and built a SQL-based ticketing and entry gate system as part of a $7M renovation project in downtown Seattle. My role encompassed performing the feasibility study and project planning, system architecture, database design, data modeling, application development, user experience design, mechanical design, and electronic engineering, while interfacing with external systems such as credit card processors, ORCA and the Kraken app.
