About


Eric ProeglerThe newest member of the PerfBytes team is Eric Proegler who, after spending 16 years working in software testing and specializing in performance and reliability testing for 13 of those years, it seemed like a perfectly normal idea to start podcasting with those crazy PerfBytes guys. I mean, how much worse could it get? But seriously, he previously worked in the Electronic Content Management space, spent 10 years leading Performance Engineering for a vendor, presenting at technical conferences, writing white papers and support policies, designing technical implementations, and taking technical leadership in Advanced Capture (OCR) solutions. Then he spent a few more years in sales engineering, solution design, and information management consulting. Now, he spends his time volunteering with Speak Easy to mentor new conference speakers and increase diversity in testing conferences and as a lead organizer for WOPR, the Workshop on Performance and Reliability. He has presented and facilitated at CAST, WOPR, STPCon, PNSQC, and STiFS. After last year’s CAST, he helped to form the AST Committee on Standards and Professional Practices in an effort to help AST engage with issues affecting our profession as a professional trade organization. He believes passionately about the issues around tester certification and testing standards to help our community best respond to these economic tactics. In his free time, he spends time with family, avidly reads, sees lots of stand-up comedy and live music, seeks out street food from all over the world, plays video games, and follows professional basketball.


Mark TomlinsonMark 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 25 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. For the majority of Mark’s career he has worked tirelessly at all hours of the night as a testing practitioner and consultant using the leading products for performance testing, profiling and measurement. He has also consistently established close ties and relationships with the major vendors who create these tools. Mark worked for six years at Microsoft Corporation as a performance consultant and performance engineer in the Microsoft Services Labs, in the Enterprise Engineering Center and in the numerous SQL Server labs as a member of the SQL Customer Advisory Team. All the while he helped to foster the success of Microsoft’s top-tier Enterprise customers focused on the early adoption of Microsoft products as part of mission-critical operations. In 2008 he left the rainy Seattle locale and moved to Mountain View, California; taking a position as the LoadRunner Product Manager at HP Software. In that role he led the team to deliver leading innovations for performance testing and engineering as part of HP's suite of performance validation and management products. As an independent consultant, contractor and teacher 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.
