After my time at JD Paipai, I transitioned to JD Finance, the financial technology arm of JD.com and one of the largest fintech companies in China. By July 2018, JD Finance had 240 million active users and an estimated market value of 13.3 billion RMB.
2015 was a booming year for fintech in China—thousands of companies emerged, but many disappeared just as quickly. During this exciting period, my primary focus was designing investment products, including:
- Fund investment platforms
- The Little Vault (a savings and investment tool)
- Customer risk profile management
- Smart Investing (similar to Robo-Advisors)
Investment is a complex yet fascinating field, and I truly enjoyed working on these products—especially the rewarding experience of seeing them go live and impact millions of users.
