Eileen Ip

I turn audience and customer data into decisions — dashboards, models, and clear write-ups for media, marketing, and gaming teams.

About

I'm a data professional who spent the last five years turning messy product and marketing data into models and dashboards teams actually use. I care most about the write-up: why an approach was chosen, what it trades off, and what breaks first at scale.

Impact Reconciles to ground truth exactly across 25,892 rows — except the 3 defect types the pipeline is never supposed to silently fix.
