Hi, I'm
Yuheng Cao.
A developer in the Amsterdam area.
I mostly work with C# and .NET.
Here's what I've been building.
My project2026
Live since July 2026
where2live.app
I wanted to know how safe my neighbourhood was. So I built a way to explore the data.
467,000 postcodes across 18,500 areas, refreshed monthly. 5,000 users and paid orders in the first month.
Explore the project
Built and run independently. Public crime and nuisance data, an interactive map, and paid area reports.
