Dennis Granheimer

Over a two-month period, contributed to the Kusten-ar-klar-Chas-Challenge-2025/pax repository by building a Dockerized Node.js and Express backend alongside a React-based admin dashboard. Established a room management API with endpoints for creating and listing rooms, and implemented data visualization features for room usage. Enhanced the frontend by enabling dynamic API data retrieval on Stats and Users pages using React hooks, replacing static mocks with live data. Refactored backend structure for improved maintainability and cleaned up dependencies to ensure safer builds. Focused on stability, documentation, and standardized development environments, laying a foundation for rapid future feature expansion and data-driven insights.
