I am an independent developer using Oracle Database, tools and technology since 1992. After developing browser-based applications, using the Oracle Web Toolkit and mod_plsql for many years,
I switched to using the Oracle Application Express (APEX) framework in 2006. In 2010 I started to work as an independent consultant, focusing on Oracle Application Express. Next to developing applications, I specialized in User Interface Design and implementation in APEX, offering this service under the brand name Themes4Apex.
I'm passionate about what I do and love to share my knowledge with the Oracle APEX community.
I have been presenting at several ODTUG KScope conferences, Dutch OGh APEX Days (now called APEX World) and the DOAG, OBUG and UKOUG conferences.
When time allows, I try to write and publish articles on my blog: Oracle & Apex Geekery.
For my contribution to the Oracle community, I have been awarded with an Oracle ACE title in 2013.
