My name is Oleksiy and I am a certified DB expert at Oracle USA. Initially I was working with MySQL databases but had to retrain for the Oracle Database. And I have been working with Oracle Technologies for 5 years already. During this time our team has successfully migrated our application from MySQL to Oracle database. And later we were among the first to migrate our database to the cloud ( OCI ). Currently I have the following responsibilities: Define, design, and implement database solutions within a fast-paced, leading edge applications company. Performance trend analysis and manage the server/network capacity. Propose client configuration and implement technical solutions to enhance and/or troubleshoot the database systems.
