He felt it was a great occasion to get in contact with a lot of community members, Liferay staff and engineers and share with them experiences and new ideas. All of them are not only professionals but also special people representing great human capital. Talking and sharing experiences with other people in the Liferay Community is one of the best way to build something different, something that holds a different point of view that makes a product like Liferay complete and unique.

She has also participated in Liferay 6.2 Beta Testing and also reported some issues in Liferay's JIRA. She has also started Blogging recently.

15 years of professional consulting in all manner of domains and products has left Andrew with a pretty good survey of many products in the industry. Like most technologists he has gone through waves of change -- from loving products to developing a passion for open source and knowledge sharing. A few years ago Andrew made the jump to his first product company, the former Endeca Technologies. It was there that Andrew was first exposed to Liferay and it was love at first sight. To say he is obsessed with Liferay is an understatement -- so much so that he does not hesitate to title himself an unofficial Liferay evangelist. Andrew tries to "sell" it to any one who will listen and am constantly trying to demo the benefits to anyone with a line of sight to his laptop.

When Oracle purchased Endeca Andrew decided that this was the time to go out on his own and offer niche consulting services. Liferay is one of the products that he has chosen to specialize in. In that last few years he has managed to work on 6 separate Liferay projects with versions ranging from 5.2.3 right through to 6.1.2 -- EE and CE.

For the community, Andrew has a list of extensions he plans to build to share and an even longer list of unpublished blog posts and video tutorials. For now there just aren't enough hours in the day to get to it all so he tries to help where he can, especially in the IRC channel -- with the goal of helping new developers to the platform skip the frustrations that come with learning any new product and helping them recognize the beauties of Liferay in a shorter time.

Oliver finished his study of Applied Computer Sciences at the University of Applied Sciences in Ravensburg/Weingarten back in 2008 with a diploma degree.Since then he's been hired by the IT Service Center of the university for realizing the migration process from the previous Content Management System (CMS) over to a modern portal based solution. After doing market research Oliver quickly came across a more and more booming Liferay, starting with version 5.2 back in the day. Since then he's been working with his colleague Klaus Tagmann as a software architect and programmer on implementing feature requests specific to the university workflow and on seamlessly integrating of Java-based campus management software. With all these customization done other universities started to get interested.

In another challenging project Oliver's team managed the migration process for the University of Applied Sciences in Biberach, with Oliver being the technical project lead. Gaining all that knowledge about Liferay, coding standards and big software packages in general and still learning something new each day using different open source frameworks I try to give something back to the community by helping others in the forums.
