I am an experienced database administrator for MySQL and MariaDB. I am an American citizen and have an active security clearance. I have been working with MySQL since release 4.1. I have extensive experience in database design and implementation, writing SQL, tuning databases, and creating operational environments for database hosts. I write complex SQL (including stored procedures and functions), assist development teams with writing their SQL, debug performance problems, and diagnose issues with database performance in production. I also write Perl programs to perform a variety of database related tasks. On the operational side I install and maintain database servers, create backup and recovery jobs, define and implement replication strategies for load and recovery management, and implement business reporting platforms. My experience with database applications ranges from high-transaction large volume systems to small web applications having a single database. My work is based on *nix based systems. With the planned obsolesce of MySQL 5.7 I can help you with upgrading to MySQL 8.
