About Us:

We are a fast‑growing web services company focused on delivering high‑quality React‑based websites with top‑tier Core Web Vitals and SEO performance. Our flagship product sees heavy traffic and we’re committed to providing a best‑in‑class user experience.


Role Overview:

We’re seeking an experienced consultant to diagnose front‑end performance bottlenecks (especially around LCP, render delays, and load delays) and SEO technical issues, and to recommend and guide clear, actionable solutions. This engagement will cover both audit and advisory phases, with hands‑on guidance for implementation.


Key Responsibilities:

  • Conduct comprehensive performance audits focusing on React/Next.js rendering, code‑splitting, and resource prioritization.
  • Analyze Core Web Vitals metrics (LCP, FID, CLS) and drill into renderTime vs. loadTime delays.
  • Identify and troubleshoot technical SEO issues (site structure, meta tags, canonicalization, sitemap, robots.txt).
  • Recommend and prioritize actionable optimizations (critical CSS, image/font preloading, server‑side rendering, caching strategies).
  • Advise on Next.js‑specific best practices (SSR, ISR, static optimization, build performance).
  • Collaborate with our development team to review architecture, code patterns, and deployment pipelines.
  • Provide clear documentation and step‑by‑step remediation plans.
  • Offer ongoing performance monitoring strategies and SEO maintenance guidelines.


Qualifications:

  • 5+ years of professional experience in front‑end engineering with deep expertise in React.js and Next.js.
  • Proven track record of improving Core Web Vitals and reducing LCP/render delays on large‑scale web applications.
  • Strong understanding of technical SEO principles and hands‑on experience fixing crawl/indexing issues.
  • Expert in web performance tooling (Lighthouse, WebPageTest, Chrome DevTools, PageSpeed Insights).
  • Familiarity with modern bundlers (Webpack, Vite), CDNs, and caching layers.
  • Excellent analytical and problem‑solving skills, with the ability to translate findings into clear recommendations.
  • Strong communication skills: able to convey technical concepts to both developers and non‑technical stakeholders.


Preferred:

  • Experience with TypeScript and modern state management (Redux, React Query, Zustand).
  • Knowledge of serverless platforms and edge functions for performance optimization.
  • Background in accessibility audits (WCAG) and international SEO.


Engagement Details:

  • Hourly consulting arrangement.
  • Flexible hours, with availability for regular check‑ins and presentations.
