Worked on the code-dot-org/code-dot-org repository to deliver two core features over a two-month period, focusing on data engineering and database management using YAML. Developed analytics instrumentation for dashboards, introducing new data models and export mechanisms to enable level-based user engagement tracking. This work laid the foundation for targeted product insights and scalable analytics across user levels. Additionally, extended DMS replication pipelines by adding tables supporting Measures of Learning analytics, ensuring timely and complete data replication for learning goals, skills, and student work evaluations. The approach emphasized robust data pipeline design and database replication, with no major bugs reported during this period.
