Mark Tomlinson is a performance engineering and software testing consultant. His career began in 1992 with a comprehensive two-year test for a life-critical transportation system, a project which captured his interest for software testing, quality assurance, and test automation. That first test project sought to prevent trains from running into each other -- and Mark has metaphorically been preventing “train wrecks” for his customers for the past 20 years. He has broad experience with real-world scenario testing of large and complex systems and is regarded as a leading expert in software testing automation with a specific emphasis on performance.

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. In 2008, as the LoadRunner Product Manager at HP Software Mark led the team to deliver leading innovations for performance testing and engineering as part of HP's suite of performance validation and management products.

Mark now offers coaching, training and consulting to help customers adopt modern performance testing and engineering strategies, practices and behaviors for better performing technology systems.
