Why a Senior Next.js Web Development Vendor Matters
A junior shop wastes your budget. IRPR assigns only engineers with 5+ years of React and production Next.js experience.
We have shipped 200+ Next.js projects. Every engineer on your team has built and maintained Next.js apps in production for at least 3 years. We know when to use ISR versus SSR, how to avoid layout re-renders, and how to set up proper error boundaries.
Our average project ships in 12 weeks. In the Roadmap phase (week 2) you get a fixed quote. No surprises, no junior mistakes. We support Vercel, AWS, and Docker deployments with 99.9% uptime SLAs.
Generic Agency vs Senior Next.js Vendor
Not all Next.js vendors are the same. IRPR is a senior team that delivers production-grade code from day one.
Generic agencies assign junior devs who learned Next.js from tutorials. They ship bloated client components, missing error states, and zero tests. You pay for rewrites and endless bug fixes.
IRPR assigns senior engineers only. Every commit passes automated tests. We ship with CI/CD, Sentry error tracking, and a full test suite. You own the code and get a deployable product at the end of week 12.
- Junior devs with 0-1 year Next.js experience
- No fixed price — hourly billing runs up
- Client components everywhere, slow pages
- No automated tests in delivery
- No CI/CD pipeline configured
- No error monitoring or logging
- Senior engineers with 5+ years Next.js
- Fixed price from week 2 Roadmap
- Server components + ISR out of the box
- 100% unit and integration test coverage
- CI/CD on GitHub Actions, deployed to Vercel
- Sentry + Datadog monitoring included
How We Deliver Your Next.js Project
From idea to deployment in 12 weeks. Every phase has clear deliverables and a fixed price.
We follow the Idea-Roadmap-Product-Release framework. In week 1 you meet a senior engineer who maps your idea to Next.js architecture. Week 2 we produce a Roadmap document with wireframes, data model, and a fixed quote.
Weeks 3 through 10 we build the product in 2-week sprints. You see working software every sprint. Week 11 is QA and load testing. Week 12 we deploy to your domain with CI/CD running.
What Ships with Every Next.js Project
Every deliverable includes these artifacts. No extra charges.
You own everything. Source code, tests, CI/CD scripts, and monitoring dashboards. We do not lock you into a platform or a contract.
All projects ship with a production-ready Next.js setup. We configure Vercel Analytics, Sentry, and Lighthouse CI. Your team can take over immediately or we can continue to support.
- Source code in your GitHub repo
- Full test suite (Jest + Playwright)
- CI/CD pipeline on GitHub Actions
- Vercel project with preview deployments
- Sentry error tracking and performance monitoring
- Datadog or LogRocket logging
- Lighthouse CI score target 90+
- SEO metadata and Open Graph tags
- Security headers and CSP policy
- Deployment runbook and architecture docs
