During December 2024, Guilherme Chiarotto developed a User Vehicle Management API for the fossguild/joynride repository, enabling users to associate and manage vehicles within the platform. He designed and implemented new endpoints for retrieving and creating vehicles linked to specific users, updating the main API router to ensure proper integration with authentication and validation standards. Using Go, he created a dedicated vehicle service, defined data transfer objects, and established robust storage logic to support the vehicle data lifecycle. This work laid a scalable foundation for future vehicle-related features, improving data integrity and supporting personalized vehicle management and analytics capabilities.
