- 2. PERFORMANCE IS NOT A MYTH P E R F O R M A N C E A D V I S O R Y C O U N C I L SANTORINI GREECE FEBRUARY 26 - 27 2020 Who am I? • I am Leandro Melendez • Performance tester, scripter, engineer and idealist. Perf Manager @QualiTest • Lot’sa experience on several performance projects for 10 years. • Found lots of vices, weird paths of action and plain ignorance. • Decided to get a secret identity and wear the spandex moustache to fight against bad practices, process inertia and plain ignorance as Señor Performo. • All this through a blog (www.srperf.com), Social NW’s (@srperf), hosting the Spanish version of the performance testing podcast PerfBytes en Español. • Last, but not least, through public speaking, spreading the word of performance, which we will do here today.
