Loud City HQ — NFC-Powered Fan Loyalty Platform

Served as the sole backend engineer for Loud City HQ, an NFC-powered fan loyalty platform developed for the Oklahoma City Thunder. The platform was designed to connect fans with interactive experiences through NFC-enabled stations, allowing them to engage with the team and participate in a digital loyalty experience.
I designed and built the backend services using Python, FastAPI, Firebase Authentication, Firestore, and Google Cloud Run, developing the API infrastructure responsible for authentication, station interactions, and platform functionality.
Key engineering contributions:
Designed and implemented the backend architecture and API services.
Built 9 API endpoints to support core platform functionality.
Integrated Firebase Authentication for secure user identity and access.
Developed station authentication to validate interactions with NFC-enabled stations.
Integrated Firestore for application data storage and retrieval.
Deployed backend services to Google Cloud Run.
Implemented concurrency protections and race-condition fixes to improve reliability when handling simultaneous requests.
Developed and maintained a test suite with 135 tests to validate backend behavior and reliability.
Supported production readiness and platform activation during the NBA playoffs.
Technology: Python, FastAPI, Firebase Authentication, Firestore, Google Cloud Run, Pytest.
Outcome: Delivered the backend infrastructure for a live fan-engagement platform, with secure authentication, reliable NFC station interactions, and tested API services supporting the Thunder's fan loyalty experience.
