About this gig
I'm a UK-based performance specialist at Daedalus Design. My portfolio sites (daedalusdesign.co.uk, clwydautos.co.uk, plumbperfect.online) consistently score 90-99 on Lighthouse Performance with sub-1.5s LCP.
I don't just run a tool and send a report. I rewrite code, restructure delivery, and architect for speed** then prove it with before/after metrics.
What I optimize:
- Largest Contentful Paint (LCP) Hero images, fonts, critical CSS, server response
- Cumulative Layout Shift (CLS) Font loading, image dimensions, dynamic content
- Interaction to Next Paint (INP) JavaScript execution, main thread blocking, event handlers
- Time to First Byte (TTFB) Server config, caching, CDN, database optimization
- Total Blocking Time (TBT) Code splitting, unused JS/CSS removal, third-party scripts
- Image Optimization WebP/AVIF, responsive srcset, lazy loading, proper sizing
- Font Optimization Subsetting, preload, font-display, variable fonts
- Caching Strategy Browser, CDN, edge, service worker, stale-while-revalidate
- Critical CSS & Resource Hints Inline critical, preload, preconnect, DNS prefetch

FAQ
Do you guarantee a specific PageSpeed score?
Premium: Yes — 90+ mobile, passing CWV. Standard: Target 90+, typically achieve 85-95. Basic: Audit only.
What platforms do you support?
WordPress, Shopify, Webflow, static sites (Astro, Next.js, Hugo, 11ty), custom PHP/Node/Python, headless CMS. Static sites are easiest to optimize.
Will you break my design/functionality?
No. I test every change in staging. Visual regression testing included. You approve before live.
My host is slow — can you fix that?
I optimize what's possible on your current host. For TTFB >600ms, I'll recommend migration (included in Premium).
How do you measure success?
Lab data: Lighthouse CI (every deploy). Field data: CrUX (28-day rolling), custom RUM. Both must pass.
Do you offer ongoing monitoring?
Premium includes 30 days. Monthly monitoring available as retainer (£99/mo).
