What This Project Shows

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

Fast shipment - Every feature within five working days
Deep, holistic approach - Tracing the full journey, not just part of it
Knowing when to push - With evidence

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

0.5% share rate - Almost nobody shared posts
95% drop-off - Recipients hit a login wall and left
Dead-end funnel - Even past the login wall, users couldn't reach posts outside their job category

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.

Floating engagement panel - Share button always visible mid-scroll, because users decided to share after reading a great comment, not at the top
Removed the login wall - Moved signup prompts to natural interaction moments (liking, commenting) instead of blocking access
