Christo Kutrovsky

An Oracle ACE with a deep understanding of databases, application memory, and input/output interactions, Christo is an expert at optimizing the performance of the most complex infrastructures. Methodical and efficiency-oriented, he equates the role of an ATCG Principal Consultant in many ways to that of a data analyst: both require a rigorous sifting-through of information to identify solutions to often large and complex problems. A dynamic speaker, Christo has delivered presentations at the IOUG, the UKOUG, the Rocky Mountain Oracle Users Group, Oracle Open World, and other industry conferences.
