I started to develop automated regression tests for biggest Netherland's auction http://marktplaats.nl (owned by Ebay) in 2007 year. We used Mercury QTP for that time, but later we have moved to an excellent Open-source project Selenium RC, Java and Eclipse IDE. It was full time job and I participated in test-framework development and implemented some tests as well. Team had 7 members. Later I was just a programmer of applications (software developer) and participated in automated tests development as freelancer, just occasionally. Selenium RC can be used for data-mining as well and some projects were completed for this purpose. All other projects except marktplaats.nl were developed by me alone. Some projects were created for customers and some just for a portfolio or due to interest.

Used technologies: C#, XPath, HTML/CSS-selectors, Selenium RC, Selenium WebDriver.
