Peter Mesotten

Peter is 29 years old, lives in Belgium and is a proud dad of a one-year-old boy. He has been working with Liferay since joining ACA IT-Solutions, an IT company specializing in Java and Java-based ECM solutions for the Benelux. It all started off by rebuilding the company website in Liferay Portal, version 5.1.1 at the time. The size of Peter's Liferay team quickly increased while he took on the role of coaching and mentoring the newbies.

Peter has been given the opportunity to present at Liferay roadshows, symposia, user group meetings and has also assisted in implementing ACA's Marketplace portlets. Nowadays, Peter takes on the role of technical lead in Liferay projects. Since October 2013, he proudly calls himself a Certified Liferay Professional, together with 3 of his colleagues.

Krzysztof Gołębiowski

Krzysztof started using Java related technologies during his studies at Military University of Technology in Warsaw. Like every respectable IT engineer, after graduation in 2010, he started working as a consultant on enterprise projects for large companies where he gained experience in design and implementation of proprietary ECM/BPM systems. At that time there was a high risk that he would grow old deploying and customizing closed-source solutions created by hundreds of anonymous programmers. Fortunately at the end of 2011 he got introduced to Liferay which allowed him to build enterprise-level software without losing the fun of coding, and let him go deeper into Open Source world.

Krzysztof has been involved in all phases of portal development ranging from business requirements management through portlet implementation, to conducting professional trainings. He participated in a few large projects for Polish public sector but currently spends most of his time creating portals for private companies. He is actively involved in Liferay Community, participating in Forums, reporting and fixing JIRA issues. He was at first Liferay DEVCON in Berlin and took part in Liferay 6.2 Beta Testing Program. In the future he wants to launch long planned apps on marketplace and create own technical blog.

The company which lets Krzysztof develop his Liferay skills, and what is more important, supports his contribution to the community is Xentivo Consulting located in Warsaw. In the nearest future its ECM branch will create a new brand - RedPaper.

David Nebinger

David stumbled upon Liferay in 2006 while looking for an open source portal platform for an intranet application implementation. He started with version 4.2 and went through the version 5 and 6 upgrades. David enjoys helping others on the forum, and does so in the spirit of open source. At times, his sense of humor takes some time to recognize and master. One of David's goals is to try and learn something new from Liferay every day.

David graduated from Bowling Green State University in 1995 w/ a Bachelor of Science in Computer Science. He comes from a background of C, C++, and Java, with the last 10 years spent developing Java web applications (the last 6 of those years solely on the Liferay platform.)
