What This Project Shows

Both stories start with something small, and I went deeper because the full picture told a different story

Impact

Every feature shipped within five working days. Community metrics were cited in the company's $120M Series D.

Situation

Remember is Korea's largest professional network: 4.5M users, a quarter of the country's business professionals

The company was shifting from a utility (business card scanner) to a daily platform. Community was the key, but the MVP wasn't gaining traction. I was the sole designer, shipping almost every week.

Using Data to Find the Real Bottleneck

Problem

A PM asked me to fix the share button, I traced the full sharing flow from both sides instead

Impact

New design allowed users to share posts more easily and to engage more

Approach

Pushed to ship two changes together. Easier sharing into a dead end makes it worse.

Designing for Lasting Engagement

Problem

Gift card campaigns drove more posts. Numbers went up. But the professional tone was getting diluted.

Approach

Brought this back as a strategy question: we're incentivizing the wrong behavior.
