Learco Brizzi started working with the early versions of Oracle Forms (3.0), Reports (1.1), and Designer (1.2.1), after he received his Master of Science degree in Information Technology in 1993. When WebDB was launched, Learco took the first steps in building Internet applications. When APEX (HTML DB) hit the market, he saw the potential of this tool and built a complete music download store with it in 2004, including integration with 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 technologist, trainer of advanced APEX courses, organizer of seminars, board member of the OGh (the Oracle user group in the Netherlands), and member of the editorial committee for Oracle magazine OGh Visie. For OGh Visie, he's responsible for the yearly APEX World event that had about 300 attendees in 2013. Since 2013, he's also a member of the APEX Feature Advisory Board.

In 1999, Learco started his own company, Itium, that specializes in Oracle technology and launched the APEX plug-in website for community APEX plug-ins: http://www.apex-plugin.com. He is the co-author of the book Oracle APEX Best Practices, published by Packt Publishing.

In May 2010, Learco was awarded the Oracle ACE membership.
