Core Web Vitals Fix Sprint · $149 · 3 business days after access · Coming soon
Fix the speed problems your real users feel, not just the lab score.
A focused sprint on one site built with Next.js, Astro, React or similar. I compare real-user data (Chrome UX Report / Search Console) with lab tests, find what's hurting LCP, INP and CLS on your most important templates, and fix it in your code.
Core Web Vitals Fix Sprint is a fixed-price service from ChikuOS, run by Siddharth Mishra, an independent developer in India. Green in Lighthouse but failing real-user Core Web Vitals? I find the cause and fix it in your code. It is planned at $149 with a turnaround of 3 business days after access, but it isn't available to buy yet.

What you get
- Field vs. lab diagnosis for up to 3 key page templates
- LCP fixes: image sizing and formats, preloading, fonts, render-blocking scripts, server/edge caching
- INP fixes: heavy JavaScript, third-party scripts, hydration and long tasks
- CLS fixes: reserved space for images, ads and embeds, and font swaps
- Before/after Lighthouse numbers and a note on when field data will update (about 28 days)
- Changes as a pull request within 3 business days of access
Field data updates over a rolling 28-day window, so improvements show up in Search Console gradually. I can't promise a 'good' rating if the bottleneck is a third-party script you choose to keep, and I'll tell you if that's the case.

Who it's for

Not if a third-party script you keep is the bottleneck, and I'll tell you if so.
