Top SchoolKevin Gisi is an engineering manager with 18 years of experience building high-performing teams and production-grade systems, currently leading Calendly’s contacts platform and shepherding the safe migration of 500M+ records with zero downtime. He blends product and design fluency with deep technical judgment—driving AI-first practices, cross-functional delivery, and hiring to close skill gaps so teams ship end-to-end.

Known for coaching engineers through blind spots to measurable growth, he values delivering value over writing code for its own sake and often opts for pragmatic decisions that avoid unnecessary build work. Based in Madison, WI, he pairs a long history of frontend and backend engineering with a background in performance-sensitive media and tooling.
