This URL redirects to https://github.com/danurbanowicz.

Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. The redirect is temporary (302/303/307), so it is treated as a detour rather than a move and history stays here.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).
