About

I’m Junjie, an independent app developer in Singapore.

My first app, and the one that kickstarted my accidental career as an app developer, is Due. I taught myself Objective-C to ship its first version in September 2010, and I’ve been working on it ever since. It has kept my family fed, among other things, and I’m incredibly grateful for that. Along the way I also made Dispatch with my buddy Hon Cheng.

But I wasn’t always that geeky. Before that, I co-founded Phocus, a photography school in Singapore. And before that, I studied at the Wee Kim Wee School of Communication & Information at NTU to be a journalist — until I got cold feet after learning how long journalists work. I did everything I could to not be a journalist, like setting up a photography school and making apps.

That is why I make apps today, and why this blog is mostly about doing that independently.

This site has been around since 2005. Most of what I wrote here back then has been retired; a few posts that still hold up are kept at their original addresses.
