IRPR's premium website modernization consultants rebuild outdated sites using Next.js 14, Vercel, and Tailwind CSS. We handle everything from legacy ASP.NET or jQuery migrations to full-stack React with GraphQL backends.
Each project ships in 8-12 weeks with a fixed price between $80,000 and $250,000. We deliver a live production app, source code in your repo, and automated CI/CD pipelines. Our sites meet HIPAA, PCI-DSS, or SOC 2 compliance depending on your industry.
We work for CTOs whose legacy platform crashes weekly, VPs of Product losing revenue due to slow load times, and founders launching a SaaS that needs a secure, scalable front end. Marketing directors hire us to turn a static brochure site into a conversion engine.

Why hire premium website modernization consultants
A modern website is not about a new coat of paint. It is about speed, security, and conversions.
IRPR's premium website modernization consultants have rebuilt over 200 products across 50 countries. We use Next.js 14, Vercel, and Tailwind CSS to deliver sites that load in under 2 seconds on 3G. Our clients see a 30-50 percent increase in conversion rates within the first month of launch.
Every modernization project starts with a 2-week Roadmap phase where we audit your existing code, infrastructure, and traffic patterns. We then fix the price for the full build. No surprises. No hourly billing.
Generic dev shop vs premium website modernization consultants
Not every agency treats a rebuild as a product. Here is how IRPR is different.
- Uses hourly billing that inflates costs
- Rebuilds in the same legacy framework
- No performance or accessibility audit upfront
- Delivers code without automated tests
- Hand-offs to junior developers mid-project
- No post-launch monitoring or SLA
- Fixed price after 2-week Roadmap phase
- Migrates to Next.js 14, Vercel, Tailwind CSS
- Audits Core Web Vitals, WCAG, and security in week 1
- Ships with CI/CD, end-to-end tests, and Sentry
- All work done by senior engineers only
- Provides 99.9% uptime SLA and 30-day post-launch support
Our modernization process
We follow a predictable 4-phase process that de-risks every rebuild.
Each phase has a clear deliverable. You know exactly what you get at the end of every sprint. No guesswork.
We use tools like Linear for ticket tracking, GitHub Actions for CI/CD, and Vercel for preview deployments. Every pull request generates a live preview URL for your team to test.
What ships with every project
You do not just get a new website. You get a production-ready system with all the infrastructure.
Every deliverable is documented and tested. You can hand the project to any developer on day 31 with confidence.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions and Vercel
- Sentry error tracking with alerts to your Slack
- Sitemap and structured data for SEO
- WCAG 2.1 AA accessibility report
- Lighthouse performance report showing 90+ scores
- Load test results from k6 showing 10,000 concurrent users
- Documented handoff guide with environment variables
- 30 days of post-launch monitoring and support

Why teams hire us.
Fixed price after audit
Every project starts with a 2-week Roadmap phase where we audit your code and infrastructure. After that, we give you a fixed price. No hourly billing, no change orders, no hidden costs.
Senior engineers only
We do not staff juniors. Every engineer on your project has at least 8 years of experience. Your lead engineer has shipped over 20 modernizations before.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and WCAG 2.1 AA compliance as part of the build. No separate audit phase needed. Your site is compliant on day one.
Zero downtime migration
We run your old and new sites in parallel for 2 weeks. DNS changes happen during low traffic hours. Your users never see an error page.
Full code ownership
You own every line of code. We put it in your GitHub repo with a permissive MIT license. You can take the code to any developer after the project ends.
Post-launch SLA
We provide a 99.9 percent uptime SLA and 30 days of active monitoring after launch. If something breaks, we fix it within 4 hours.
