Résumé

Summary

As an IT professional I am extensively experienced in unices administration, networking and security. I am familiar with variety of unices based on the Linux OS and plenty of Internet services, protocols and standards too. Information security and performance have been primary interests of mine as well as computer science in general. Free and open source software (FOSS) has been (among other personal and technical interests) one of my favourite priorities since I have got my first computer. Therefore my insight in this area is deep.
