Challenge 3: How I transformed the most critical user action into a measurable business signal

The most defining user action on the platform, contacting a seller, was going unmeasured, and we scoped the work to fix that.

Phone numbers had always been displayed openly, so there was no way to count how many users actually reached out to sellers. That contact moment is the core transaction on a classifieds platform, and for paying agents, it is the most direct signal of whether they are getting value. I worked with the team to mask phone numbers behind a reveal button, making every tap a tracked event the business could tie to agent value.

What had run for years without a number on it became one of the platform's primary KPIs, giving both the business and its agents a real read on the leads Muaban was generating.
