The brief
Lensvelt's storefront was failing Core Web Vitals, largely from unoptimised product imagery and third-party scripts loading ahead of anything the customer could actually see.
What we built
An image pipeline serving properly sized, compressed assets per breakpoint
Script loading order reworked so nothing non-essential blocked the largest contentful paint
An audit of every third-party script for what it was actually measuring
Monitoring so a regression gets caught before it ships to everyone
