During October 2025, Arn Smith developed analytics-driven features for the Immpression-Dev-Team/backend and mobile-app repositories, focusing on image engagement and user notifications. He designed and implemented a new image view tracking model in Node.js and MongoDB, enabling per-user history and automatic view count increments while refining RESTful API conventions. On the mobile side, Arn enhanced user engagement tracking in React Native, ensuring unique image views per user and updating notification cadence to trigger every 60 seconds. His work established a scalable foundation for reliable analytics and cross-platform data consistency, demonstrating depth in backend development, API integration, and data modeling for analytics.
