Mike is the co-founder of Percy and Principal Engineer at BrowserStack. Mike loves architecting and building well-designed applications, distributed systems, UI/UX flows, and system infrastructure.


Slowness, noise, false positives, and flakiness! In this webinar, Mike will talk about the engineering challenges he faced while building the Percy Visual Engine and how he overcame them.

He will also walk through all the new unlocked capabilities and features—Pageshift detection, handling false positives due to anti-aliasing, and using machine learning to detect shifts humans wouldn’t care about.
