Available for hire
I am available for hire, but unfortunately, due to other arrangements, only on a day-by-day or at least week-by-week basis.
I would love to do projects for iOS or Android, but I would not claim that I am in any way an expert in these things. This hopefully changes in the future.
I am also, should the need arise, available for pure consulting work, for example examining technical feasibility for a project.
My daily rate pretty much depends on the customer, the timeframe and the work that needs to be done, but please don't ask me for a daily rate of 200 EUR or to work purely for equity. For one I am relatively risk averse and also I am very, very good at what I do.
Projects I've been involved in
Depfu helps your team to keep your Rails/Ruby dependencies up to date.
Novation Circuit Components
Novation is a very successful maker of wonderful synthesizers, controllers and other musical devices. Their Circuit Groovebox is a great play on the Button Grid as a musical input device.
I am responsible for most of the development of the Circuit Components web application, which uses Web MIDI and Web Audio to allow you to back up the Circuit and customize it's sounds.
The app is built unsing Ember.js and uses a lot of cutting edge browser tech, which sadly means it's currently only running in Blink based browsers (Chrome and Opera).
GPredictive is a Hamburgian startup that helps retailers to optimize their print and online campaigns by using machine learning.
I was responsible for the development of the web application that will become the centerpiece of GPredictive's product offering in 2016.
I've also helped a bit with building prototypes for internal tools and put on my old rusty recruiting hat at the end of 2015.
liv3c0der is a live coding music performance tool based on Web Audio technology I've built for a live act once and have been continuously improving for some years now.
It's kind of the gift that keeps on giving, I've given more talks on this tool (and the Web Audio API) than on any other subject.
A large, multi-layer eBook project for the german publisher Rowohlt. I've built a build pipeline for generating multiple different eBook formats with interactive elements from XML files.
Also part of the project was building a web app that would orchestrate several out-of-book interactions such as text messages, emails and even phone calls depending on the reading position of the reader.
The new mobile website of the now defunct financial times deutschland was a rather short lived project. I really enjoyed building both the prototype with the amazing precious forever and the final product with a team that included my dear friends Dennis Reimann and Eckhard Rotte.
A very cozy but active arts community by a hamburgian artist and illustrator named Jochen Hein. This was the first Rails project my splendid former employer mindmatters.de ever did, and the code based has been laying dormant for a few years after it became clear that it was not viable for both Jochen and mindmatters to keep maintaining it. After I started freelancing in early 2012, I became part of the artdoxa team and I am now currently in the rather tedious process of refactoring that old app from the inside out to make it more feasible to start actively developing on that code base. Watch this space
This is a smallish hobby project of mine that gets very variying attention from me. The idea is to build a library tool like delicious library for mac, but do it online. There's lots of things I'd like to add (for example a bar code reading app for mobile phones to quickly scan in a lot of books), but it currently doesn't really have a very high priority.
Another private hobby project: I love T-Shirts and straightouttacotton.com aims to be just a very comprehensive database of cool, funny or simply beautiful T-Shirts (and the occasional hoodie).
Done with my buddy Sven Steinheisser at the Music Hackday Amsterdam in 2012, the cloudtracker is a functional web version of Protracker, a four track, sample based music creator written for the AMIGA. It uses the Web Audio API to render the .mod files in real time.
