Pressure
My own product, an iPhone and Apple Watch app on the App Store since July 2026.
About me
I’m James Han, a freelance software developer in Orange County, California. I build websites, apps and automations.
Both of my projects began with people putting up with something every day. Friends who run together had to post each workout to their group chat by hand, and guests at the restaurant group I work for had to ask about allergens dish by dish. I like finding problems like that and fixing them properly, so they stay fixed after I hand them over.
I build out your project end-to-end until you are 100% satisfied. I am detail-oriented, communicate well, and have a relentless desire to be better.
