Antoine Gantier led core engineering for the rommapp/romm repository, building a robust ROM management platform with a focus on scalable metadata integration, resilient API design, and modern frontend architecture. He implemented features such as smart collections, multi-source metadata enrichment, and a reusable media carousel, using Python, TypeScript, and Vue.js. His work included backend optimizations for data integrity and migration safety, frontend modernization with Composition API and state management via Pinia, and comprehensive test coverage. By refactoring legacy systems and introducing efficient caching, Antoine improved reliability, developer productivity, and user experience, demonstrating deep technical breadth across full stack development.
