%d7%9e%d7%99%d7%9b%d7%90%d7%9c7-52My name is Michel Depiesse (pronounce “de pi es”). Please have a look on LinkedIn. I live in Antwerp. I am a database developer and administrator working with PostgreSQL and Linux. I would like to become hyper-excellent in SQL programming, query optimization, database design & administration… Being at this time just excellent, I bought an entire library on these matters… Having extensive experience with relational database systems and being open-minded, I am able to easily adapt to any business and to any Rdbms. By the way, as (almost) everybody, I have a preference for PostgreSQL. I study for the PostgreSQL certifications organized by Dalibo.

I lived in Brussels. I got degrees in IT and I worked for years in big companies. After some years with C and Perl programming and Unix administration, I worked with databases as administrator, developer and designer with Oracle and SQL Server. I learned the relational model and I enjoyed it because I love logic since my early youth. At the age of twelve, I had an awesome mathematics teacher who taught set theory, propositional and predicate calculus, truth tables, boolean algebra…
