Tiberiu Covaci started his developer career in 1991, but it wasn't until 1994 that he was introduced into the Microsoft world of technologies. He moved from Romania to Sweden 1996, to work as a programmer. Since 2004 he has worked as an independent trainer, teaching .NET programming on all levels, but what he loves most is teaching introductory courses, because it gives him a chance to influence the future .NET programmers. He works closely with Microsoft, both as Subject Matter Expert for the MCPD exams, and Technology Reviewer in the new Microsoft .NET 4.0 courses that are under development. He is a member of the MCT Advisory Council, INETA Speaker, and INETA Country Lead for Sweden. His passion for new technologies made him a very popular speaker at conferences like TechEd, DevReach, TechDays, Öredev, ScanDev and MCT Summit. He is interested in technologies like multi-core programming, ASP.NET, new programming languages and trends, and applications security. Whenever he gets the time, he blogs at http://blog.multi-core.net/.
