What I'm looking for

I need a role with a non-usual daily work time.

At e-Core, I worked as a Java Senior Developer developing systems with Java, with a focus on enterprise JavaEE. My experience spans intranets, CMSs, educational and city management systems, social networks, business management, and retirement and pension management.

At Eckert&Caine GmbH&CoKG - Software for Management, I worked as an analyst, architect, and developer on a web system, guided the team mainly on back-end development and maintenance of core features, and was responsible for server deployments. I’m a Sun Certified Programmer for the Java Platform, SE 6, and I need a non-usual daily work time.
