Proven track record with senior Next.js teams
Every project is staffed with senior engineers who have built production Next.js sites for global brands.
IRPR has shipped over 200 products using Next.js since 2018. Our engineers average 10+ years of experience and focus entirely on React and Next.js ecosystems.
We benchmark every site against Lighthouse 90+, Core Web Vitals, and real user monitoring. Clients see an average 40% improvement in page speed after migrating to our Next.js builds.
Why generic agencies fail at Next.js
Most dev shops treat Next.js like a template builder. IRPR treats it as a production framework.
Generic agencies reuse Wordpress templates and bolt on Next.js without understanding server components, edge functions, or incremental static regeneration. This leads to slow sites and fragile code.
IRPR writes custom code from scratch, tunes Vercel caching headers, and configures ISR for content that changes hourly. Our sites score 95+ on Lighthouse and handle 10,000 req/s without scaling headaches.

Our process for building senior-grade Next.js sites
Four phases, documented decisions, continuous feedback. No guesswork.
We start with a 1-week Discovery sprint to map user flows and tech constraints. By week 2 you have a fixed-price Roadmap with wireframes and architecture decisions.
Build phase delivers a working MVP every 2 weeks. Launch includes Vercel deployment, Sentry monitoring, and a 30-day hypercare window.
What ships with every Next.js project
You get complete ownership and production-ready infrastructure from day one.
No black boxes. Every project includes the source code, database migrations, and deployment scripts. We set up monitoring and error tracking before launch.
Our delivery checklist ensures nothing is forgotten — from API rate limiting to SEO meta tags and image optimization.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Vercel production deployment with domain
- Sentry error and performance monitoring
- Lighthouse audit score 90+ across all pages
- Responsive design for mobile, tablet, desktop
- WCAG 2.1 AA accessibility pass
- SEO meta tags, sitemap.xml, robots.txt
- Documentation for architecture and deployment
