2 Experience

I got my computer science PHD in 1987 with a compiler design subject from the Universität Saarbrücken, Germany. I then worked on microcontroller realtime systems and adapted the GNU C compiler for use with microcontrollers. I develop web applications since 1999, starting with internet access to the archive of a regional newspaper and an editorial system for planing and production support of an association newsletter. I then worked for a medium sized German publisher (1.000 employees) and have been a key contributor to the design and implementation of the backend of his internet sites and internet/intranet applications. These applications included:

• open information portals (4)
• special focus portals (20)
• product portals (hundreds)
• closed customer portals (thousands)
• shops (4)
• editorial systems (2)
• electronic exhibitions (6)
• webservices

My primary tasks have been:

• analysis of marketing requests and solution design
• backend architecture design
• backoffice (SAP, LDAP) integration
• integration with partner services (signle sign on, remote login, customer webservices)
• problem analysis and fixing
• performance analysis and tuning
• database (ZODB ("Zope Object DatabBase")) optimization and repair

Since 2009, I work as an independant consultant.

Since 1999, I develop free open-source software components. You find them partially here on this site or search for "Dieter Maurer" on http://pypi.python.org.
