Performance testing tools for JMeter, k6 and Gatling

"I would like to take this opportunity to personally thank Mark for the fantastic job he has done for my team at TransUnion. Mark has taken us from almost no performance testing into place where it is now embedded into our release process. Not only that, we are now confident with our growth projections as a team and a division and have the evidence to support this. I would certainly recommend Mark to any recruiter and he is certainly someone I will be calling on in the future, should I require his expertise."

"I worked with Mark for over 3 years. I found him extremely hard working as well as very knowledgeable and an expert in performance test practices. Very flexible and always maintaining a calm and professional attitude even during critical and tense periods of execution. He was able to work across supplier and client teams, building exceptional relationships with them and working as one team to deliver successfully to schedule. I would gladly work with Mark again in the future if the opportunity arises."

"Mark is a highly regarded performance tester, knowledgeable, helpful, and supportive within the Global Test Practice at HP."

"As a performance test engineer, correlation is the part of the job I dreaded the most. Going through a .har file manually and figuring out which values need to be parameterized is just tedious, repetitive work that's easy to get wrong. This tool handles it for you. You feed it the .har, it spots the dynamic values, and spits out a .jmx that's already parameterized. The output is clean enough to use without much touching up."
