Her experience goes back to Oracle Forms version 2 and Report*writer. Almost fourteen years ago, she started working for Oracle Support Services for the developer competency (Oracle Forms, Oracle Reports, Sql Developer and Application Express) assisting customers with solving their software problems. During those years, she applied the knowledge she gained in other ways like coaching new engineers, team leading and teaching Application Express courses for Oracle University. One of her responsibilities in Oracle Support is Global Technical Lead Application Express. She works closely with Sustaining Engineering, Product Development, and Product Management from the Application Express team. Besides that, she is a frequent speaker for different Oracle User Groups about Application Express and SqlDeveloper. After Learco received his MSc in Informatics in 1993, he started working with the early versions of Oracle Forms (3.0), Reports (1.1) and Designer (1.2.1). When WebDB was launched, Learco made the first steps on building internet applications. When APEX (HTMLDB) hit the market, he saw the potential of this tool and built a complete music download store with it in 2004, including integration with email, reports and payment service providers. This was one of the very first serious applications ever built with APEX. Nowadays, Learco is dedicated to APEX and PL/SQL development. He is a very enthusiastic technician, trainer of advanced APEX courses, presenter at conferences, organizer of seminars, committee member of the OGh (Oracle user group in the Netherlands) and member of the editorialcommittee for Oracle magazine 'OGh Visie'. Together with a companion Learco started his own company, Itium, in 1999, which specializes in Oracle technology.
