I'm a software developer located in Berlin, Germany. I was born July 1st 1967. I'm married to Joanna Geibig, and our daughter Laila was born on December 20th 1999.

My love for computing began back in the 80ies when I was a kid of 14 years. I found out about a lonely apple II computer at school. My first computer was a Sinclair ZX81, followed by an Atari 800 and a C-64 (assembler and basic). In 1987 I got into more serious programming with the Atari ST (Modula 2 and C). I bought my first PC in 1994 on which I made my first steps with Linux (kernel 1.0). I started with OO and Java in 1996. I've worked as an employee for several companies in Germany and as a freelancer, usually as java developer.

I'm a huge fan of testing and continous integration. Recently I became very interested in the new languages which could replace or at least complement java: scala, clojure, groovy, erlang. It's a fact that future apps have to be highly concurrent and I want to be prepared.

Degree: Diplom Wirtschaftsinformatiker (FH), a german degree which is something between a bachelor's and a master's degree

My computing interests:

• Object-oriented software development and design
• Design patterns
• JVM languages (java, groovy, scala)
• Mobile applications
• Linux
• Object persistence
• Lightweight web applications

My preferred working environment/style is:

• IDE: eclipse
• Build: ant or maven
• OS: Linux
• Agile methodologies like XP, Scrum, TDD

Some projects I was working on:

• MIDI editor/bankmanager software.
• Calculation software for power plant related physics.
• Macromedia Flash file parser and editor.
• Ad sponsored internet access and ad management and distribution system.
• Cash register software. Java software running under Linux against a Microsoft backend.
• Software and configuration management system for large company networks.
• Database centric distributed room ressource management using a robust persistence layer, JakartaOjb.
• Software distribution management for large IT installations (J2EE webapp)
• Massive online gaming platform
• Job search engine http://www.jobs.de

I'm working very much with the SpringFramework including WebFlow?, Acegi Security and WebMVC - I'm just in love with the lightweight POJO approach and I'm an evangelist of spring since its early days. Recently I got very interested in the scripting hype and made my first steps with ruby and RoR
