About Mark Tomlinson
Mark Tomlinson is a performance engineering and software testing consultant.

Mark worked for six years at Microsoft Corporation as a performance consultant and engineer in the Microsoft Services Labs, in the Enterprise Engineering Center and in the SQL Server labs. His efforts to foster the success of Microsoft’s top-tier Enterprise customers was focused on their early adoption of Microsoft products as part of mission-critical operations.
