Mark Tomlinson
Performance Sherpa
Mark's career began a long-ass time ago with a comprehensive two-year test for a life-critical transportation system which literally sought to prevent trains from running into each other. Since then and for the last 27 years Mark has metaphorically been preventing “train wrecks” for organizations each and every day. 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. After decades working with "big tech giants" Mark still prefers tirelessly working at all hours of the night as a testing practitioner and consultant using the leading products for performance testing, profiling and measurement. Masquerading as his alias "The Performance Sherpa" he helps with mentoring and teaching customers adopt modern performance testing and engineering strategies, practices and behaviors for better performing technology systems.
