Dataflow Editor

To make complex data preparation accessible to a wider range of users, I designed the Dataflow editor, a visual canvas for building and managing data pipelines within MapLab.

This node-based interface allows users to intuitively connect different processing steps—from reading a cohort definition to outputting a final dataset—abstracting away the need for complex backend code. The design not only simplifies the creation of sophisticated workflows but also provides a clear, visual data lineage. This enhances reproducibility and makes the entire process easier to debug, validate, and securely share with colleagues using the platform's granular access controls.
