Senior Website Modernization TeamModernization Team
We rebuild legacy sites on modern stacks like Next.js and Sanity. Ship in 12 weeks with fixed pricing.
IRPR builds a senior website modernization team for enterprises that need to replace outdated, slow, and insecure websites. We use Next.js, React, Sanity CMS, and Node.js to deliver fast, maintainable sites.
Every project ships source code, CI/CD pipelines, automated tests, and performance monitoring. Timeline is 8-12 weeks for most modernization projects. Fixed pricing ranges from $80K to $250K depending on scope. Compliance ready for HIPAA, PCI-DSS, SOC 2.
Who hires us: CTOs at mid-market companies stuck on a legacy CMS like Drupal or WordPress; engineering directors at ecommerce brands migrating from Magento to Headless; product owners at SaaS companies needing to modernize their front-end without rebuilding the backend.

Why a Senior Website Modernization Team Matters
Outdated websites cost you revenue, security, and SEO rankings.
A 2-second delay in load time increases bounce rate by 32%. Modern sites using Next.js and static generation can achieve sub-100ms load times. Our team has rebuilt over 40 legacy sites in the past 3 years.
We don't just update the design. We modernize the architecture: headless CMS, server-side rendering, automated CI/CD, and performance budgets. Every project ships with Lighthouse scores above 90.
Generic Redesign vs. Senior Modernization
Not all web dev teams can handle complex migration.
A typical web agency might copy your old design into a new template. That leaves you with the same slow load times and security vulnerabilities. IRPR's senior team rewrites the entire front-end architecture.
We analyze your current stack, plan the migration in phases, and ensure zero downtime. Our fixed-price contract includes real performance benchmarks and automated testing.
- Copy-paste design to new template
- No performance budget
- No CI/CD or automated tests
- Uncertain timeline and hourly billing
- No accessibility audits
- Leaves you on old backend
- Full architecture rewrite on Next.js
- Performance targets (Lighthouse 90+)
- CI/CD pipeline + Playwright tests
- Fixed price 8-12 week timeline
- WCAG 2.1 AA compliance included
- Headless CMS with content migration
Our 4-Phase Modernization Process
From legacy to modern in 12 weeks guaranteed.
We start with a 2-week Discovery phase where we audit your existing site, measure performance, and define the target architecture. Then we build the entire front-end in parallel with content migration.
After launch, we hand over a complete system with documentation, monitoring, and a 30-day support window.
What Ships with Every Modernization
You get more than a new front-end.
We deliver a complete, production-ready system that your team can maintain. No hidden dependencies.
Every project includes full code ownership, deployment infrastructure, and training for your developers.
- Source code in your GitHub repo
- Next.js + TypeScript application
- Headless CMS setup (Sanity, Contentful, Strapi)
- CI/CD pipeline with GitHub Actions
- Automated tests (Playwright, Vitest)
- Lighthouse score report (90+)
- Content migration scripts
- Deployment to Vercel/AWS with monitoring (Sentry, Datadog)
- Documentation (architecture, deployment, content editing)
- 30 days post-launch support
