During November 2025, Dawid Wedrocha developed the foundational Central System scaffolding for the AliceO2Group/WebUi repository, focusing on centralized authentication and secure token lifecycle management. He implemented token management endpoints and established the initial server setup using Node.js, Express.js, and TypeScript, enabling scalable access control across the user interface and downstream services. This work addressed integration challenges by providing a clear project structure and robust API development practices. By aligning the implementation with project requirements, Dawid laid the groundwork for future feature expansion, ensuring that authentication flows are both secure and maintainable for ongoing and upcoming development efforts.
