Jaeyeong Min developed and enhanced ride-sharing and email tracking features across the sparcs-kaist/taxi-back and taxi-front repositories over three months. He built a time gap-based room search API and a frontend modal to suggest existing rooms, improving user experience and resource utilization. His backend work included migrating email modules to TypeScript, implementing robust email open tracking with UUID-based IDs, and refining data models for analytics and reporting. Jaeyeong applied technologies such as Node.js, React, and MongoDB, emphasizing maintainability through code refactoring, environment-based configuration, and comprehensive API documentation, resulting in more reliable, type-safe, and analytics-driven backend and frontend systems.

July 2025 performance summary: Delivery focused on maintainability, analytics, and type-safe backend improvements across taxi-front and taxi-back. Front-end work included cleaning up the AddRoom page, refining the ModalSimilarRooms UI (removing translation hook usage and embedding Korean text directly, plus UI margin tweaks), and adding GTM event tracking for the create_new_room flow to enable analytics-driven optimization. Backend work migrated the email module to TypeScript, improved routing and imports, and implemented email open tracking with data validation and storage; additional improvements strengthened email origins/config via environment variables and refined data models for reporting. Overall, these efforts reduced technical debt, improved data accuracy for analytics, and boosted developer velocity through clearer interfaces and stronger typing. Technologies demonstrated include React/TypeScript, Google Tag Manager integration, Zod validation, environment-based configuration, and a TypeScript-driven backend refactor.
