He started his professional career in the motion picture industry, but switched to IT in 1999. A year later he got bitten by the software testing bug and hasn’t been cured since. He has a passion for exploraty testing, testing in agile environments and, most of all, learning from different perspectives. Zeger considers himself a context-driven tester and tends to look both ways when crossing a one-way street. He is interested in parallels with other disciplines and writes about that on his “Test Side Story” blog. He worked for CTG Belgium for a long time but early 2013 he needed a new challenge and started his own company, Z-sharp, helping clients on the path to smarter testing.
