Position

Position

My objective is to utilize and extend my knowledge by participating in software projects, which employ advanced, object-oriented technologies.

Being both a software architect/developer and an experienced UNIX and database systems' administrator I'm able to assess specific requirements of a production system (e.g. performance and multi-user issues) and take them into account when defining the overall architecture, designing and implementing software.
