Me, myself and I

Alexander Reelsen

Email:

I am a Software Engineer living in Munich, working for elasticsearch, author of the Play Framework Cookbook (check the samples). I do like hacking on different stuff. I feel comfortable with modern tools like Play Framework, MongoDB, Elasticsearch, Web, Linux, Concurrency and JavaScript. On bad days I try out GUI stuff. I keep losing.
Below is a list of my presentations. If you want me to give a talk, contact me.

And it is polyglot: written in Java with bindings for other languages (currently only Ruby). Nicolas Merouze is leading the project and I am helping where I can.
