Hi I’m CJ

I am a Software Developer from Germany and I like to build things.
I regularly try to challenge myself to learn a new skill on a budget and sometimes document things on here in public. Investing a little bit of your own money into yourself typically has a pretty good return on investment.

I used to call myself a iOS software developer, but since I haven’t done it in a while I struggle to call myself that anymore. I used to work for CircleCI where I got into many fights with xcodebuild and wrote about how to work around all kinds of problems in Xcode with regards to CI.
If you have done anything related to CI/CD on or with Apple’s platforms and have written the words “fastlane” or “xcodebuild” into a YAML file before, it’s likely that you have read something that I wrote.

I also used to work for MacStadium helping them build new datacenters specifically for the needs of a Mac in such an environment. I also tried to make the iMac Pro in a 19" server rack a thing, which sadly never shipped to customers as an option…

Day to day I work on Guardian Firewall helping to lead our team to protect the privacy of hundreds of thousands of customers around the world by trying to build a public VPN service that is actually private by design. I work across many platforms and functions, multiple different ones on any given day and always strive to publish software that I’d be happy to put my name on.
