Note: I'm limited in what I can share about this project due to NDAs.

This project represents a long-term relationship with a client where we iterated on the product over time.

I architected and built this MERN stack app from scratch based on designs provided by the client. In later versions I built out a data warehouse system using AWS Glue and Amazon Athena to provide quick access to large datasets for users.

The core feature is a complex drag and drop audience builder with conditional logic that allows a user to build a custom audience using over 200 attribute filters, previously purchased audiences, and uploaded audiences. They can then download large audiences within seconds after purchasing when it previously took engaging a data scientist directly.
