OMG Digital BA is a beauty analyzer platform with backend APIs for personalized beauty flows. It also has beauty showcase that showcases make up looks from other users.

I developed the backend for OMG Digital BA, building and maintaining APIs for CMS, user, and store flows with ExpressJS and PostgreSQL. My work covered core features such as store/banner/product management, look category and recommendation flows, skin analyzer and VTO result processing, authentication and permission-based access, and error logging/monitoring. I also implemented and maintained third-party integrations for beauty-analysis services and cloud storage, ensuring stable API communication, resilient error handling, and reliable data processing across the platform.
