During May 2025, Chia-Hsuan Liu developed a foundational onboarding feature for the IntensiveCoLearning/EIP-7702 repository, focusing on structured user registration and participant data capture. Leveraging Markdown for documentation, Chia-Hsuan designed a user registration template that collects timezone, personal introductions, program commitment, and contact information, while also scaffolding a daily notes section to facilitate ongoing data collection and engagement tracking. The work established a clear data schema to support participant profiling and future analytics. Although the contribution was limited to documentation and did not involve bug fixes, it provided a solid groundwork for scalable onboarding processes and improved participant experience.
