Fflp! ?Mix & Match? for Small Kids

Comments.app

My second own mac app! Being in the past a podcast I once used the “WordPress Notifier” to be notified in Mac OS X when someone posted a new comment. Sure you can get an Email but we have our Inbox full enough and I love having native apps. There seemed to be no apps doing this anymore (the WP notifier was abandoned on OS X) and thus I built something a bit bigger allowing Bloggers to manage their comments inside an app.

organize own Cocoa conference

For years I’ve been willing to organize my own Cocoa conference, highly inspired by the NSConference in the UK, but in the middle of Europe. So I made it, I organized one in September every year since 2012, with many known speakers from around the world and about 100 people for the first year. It was an amazing success, did it again in September 2013 and the 3rd Edition will be in September 2014. It doesn’t “fill” my year (neither my bank account) though so I’m still open to other contracts.

Also, since many years I’ve built myself my own chance to work
with tools like Final Cut Pro and would love to deal with it for a client.

Seven Principles AG, a 650-employee company, hired me as their
first official dedicated iOS Developer. I’m working with 3 other iOS
Developers. We work for important clients like German Post/DHL or Vorwerk. On top of that, 7P let me organize Objective-Cologne, my yearly conference, under they name/budget. Additionally I am
preparing a Cocoa/Swift Bootcamp for other developers that should be ready to jump on iOS after a week full of learning its beauty.
From the get go I dealt with 7P to be able to do some contract work aside. It means I can’t do onsite contracts (e.g. 1 month or longer) but it’s totally feasible for me to work remotely in the evenings, week ends, and whenever needed ask for a holiday so I can work on an aside project.

Mac App

I met Rheinfabrik’s CEO at my Conference last year and we kept in touch. He then asked me to work on a Mac App for one of their client which is basically a “Web” Wrapper but with a lot of complexity and security so users of the app don’t have an easy access to the actual content. Being a Mac lover, I was super happy to be able to not do iOS, for once ;-)
