Hi, I'm Kyle Lieber

Staff Technical Lead at HubSpot

I'm a Staff Technical Lead at HubSpot, focused on foundational backend platforms, identity, and access control.

I focus on taking complex, high-blast-radius tier-0 services—the critical systems that power authentication, tenant segregation, and every customer page load—and re-architecting them into resilient, decoupled platforms. I care deeply about moving teams out of firefighting into calm, predictable reliability, and building systems other engineers can depend on.

In my personal time, I enjoy tinkering with self-hosted home automation (Home Assistant and Hubitat) and woodworking in my garage.
