Started working with Selenium as a personal initiative to find a free alternative to QTP that could fit better in an agile developing environment.
I gave courses and presentations for introducing Selenium to directors and mates and managed the adoption of Selenium as the main tool for test automation in the QA area I'm part of.
Now I'm the person in charge and the first referral in tasks related with tests automation in general.
I have experience with Selenium Core for basic and easy to run tests, Selenium IDE for test's structure creation and Selenium RC with Python driver for more complex tests.
The tests I created involve things like excel data extraction and Data Driven tests, Data Base access, HTML, reStructuredText and PDF reports generation, desktop automation libs interaction (using pyWinAuto), etc.
Additionally,I've made a buildout recipe for automating and simplifying Selenium installation and tests execution for Zope/Plone projects.
I've created an installation guide for Python, Eclipse and Selenium RC on windows (available at Selenium's site).
I'm a contributor of the Selenium project as one of the four main members of the team in charge of the content in the new official documentation for Selenium 1.0.
