About Me

Born in Shanghai, I moved to London as a teenager and then graduated from the London School of Economics with a BSc and an MSc, studying mathematics, economics, and finance. I now work at KPMG in London, focusing on technology-driven projects.

I love exploring new cuisines, from trendy hotspots to hidden gems tucked away in local neighbourhoods. I also run regularly along the Thames, watching Tower Bridge through all four seasons and how the river changes with time and light.

Outside of work, I like to code just for fun. This website is one of my personal projects — a space to capture the small moments of my twenties, memories that will only grow more precious with time.

A Map of Memories

Capturing moments from every place my camera has been

🌍 Click on a country to view photos

Because each photo holds a story beyond the frame. If someone told my 14-year-old self what I'd be doing in my twenties, I wouldn't have believed them.

So what about the next decade? What will I become? Life is so random, but that's what makes it fun. And the journey will continue...

Thanks for reading this far.
