I’m looking for a developer who can take dhoomdb.com to a healthier Core Web Vitals score and tighter search-engine hygiene. The stack is split between a Next JS front-end and Spring Boot services, so you’ll need to be comfortable jumping between React, server-side rendering, and Java API endpoints. Here’s what I need you to tackle: • Core Web Vitals: eliminate CLS shifts and push LCP well under Google’s recommended thresholds. Page-loading speed on the UI is my top visual priority. • Internal architecture: tighten internal linking, add correct canonical tags throughout, and remove any competing URLs. • Programmatic sitemap: generate and expose an up-to-date XML sitemap from the codebase (no manual plugins). • Defect sweep: resolve issues on both the UI and the API layers—broken components, slow endpoints, or anything hurting crawlability or user flow. I’ll review the work with Lighthouse, PageSpeed Insights, and Chrome DevTools. Acceptance is based on green Core Web Vitals in mobile tests, a valid sitemap in Search Console, and zero critical errors flagged by Screaming Frog or similar crawlers. If you’ve previously tuned Next JS performance, handled Spring Boot optimisations, and can prove measurable SEO wins, let’s talk about timelines and milestones.
