- Modeled 23 content types in Contentful and built reusable page sections in Next.js with live preview and field validation, so marketing now publishes 85% of new pages with no developer ticket.
- Shipped 140+ campaign and event landing pages from shared sections, with A/B tests in Optimizely on headlines, form length and customer logos, lifting the trial signup rate on paid traffic from 3.1% to 4.4%.
- Moved 2,800 blog and resource URLs into a new folder structure with a 301 map, canonical tags, XML sitemaps and schema.org markup checked in Screaming Frog, keeping organic sessions within 3% of the old level after launch.
- Cut p75 mobile LCP on the top 50 landing pages from 3.6 s to 2.1 s with responsive AVIF images, self-hosted fonts and chat and ad scripts delayed until first interaction, tracked in PageSpeed Insights.
