Senior Website Modernization AgencyModernization Agency
We rebuild legacy websites on modern architectures. Your team gets faster load times, better SEO, and lower maintenance costs.
IRPR is a senior website modernization agency. We rebuild legacy sites using Next.js, Sanity or Strapi headless CMS, and cloud infrastructure on AWS or Vercel.
Each project ships in 8-12 weeks. Fixed pricing from $80K to $250K depending on scope. We handle compliance like PCI-DSS for ecommerce and HIPAA for healthcare.
We work with CTOs at 10-year-old SaaS companies who need to re-platform their monolith. Product directors at media sites who need to scale traffic. Engineering leads at ecommerce brands who want sub-second page loads.
Types of software we ship.
Full-site replatforming
Moving from WordPress or Drupal to a headless architecture. We use Next.js as the front end and Sanity or Contentful as the CMS.
Headless CMS migration
Migrate content and templates from a legacy CMS to a headless system like Strapi or Contentful. Preserve SEO rankings with 301 redirects.
Legacy framework upgrade
Upgrade AngularJS, Backbone, or jQuery sites to React or Next.js. Zero downtime during migration with incremental adoption.
Performance optimization rebuild
Rebuild key user flows to achieve Lighthouse scores above 90. Use lazy loading, code splitting, and CDN caching.
SEO migration with redirects
Move to a new domain or URL structure without losing rankings. We map 100% of old URLs to new ones and monitor 404s.
Micro-frontend decomposition
Split a monolithic front end into independently deployable micro-frontends using Module Federation. Each team owns a piece.
Static site generation (SSG) rebuild
Convert a dynamic site to SSG with Next.js for faster load times and lower server costs. Perfect for marketing and content sites.
Accessibility and compliance overhaul
Bring the site to WCAG 2.1 AA standards. Integrate axe-core and Lighthouse audits into CI/CD. Legal compliance for ADA.
We build for every business type.
Ecommerce brands that need headless storefronts
Media and publishing companies
SaaS and enterprise platforms
Nonprofits and associations
Healthcare and pharma organizations
Why you need a senior website modernization agency
Your legacy site is costing you money every day it stays online.
Page load times over 3 seconds lose 40% of visitors. Google uses Core Web Vitals as a ranking signal. A modern site with Next.js can load in under 1 second. That alone improves conversion rates by 20% or more.
Maintenance on old codebases burns developer time. We have seen teams spend 60% of sprint capacity patching legacy bugs. After modernization, that time drops to 10% for upkeep.
What makes a senior modernization agency different
Not all website rebuilds are the same. Here is how IRPR compares to generic dev shops.
Generic shops push templates and drag-drop builders. They deliver a site that looks new but runs on the same old architecture. Within six months you are back to slow load times and security patches.
IRPR assigns senior engineers only. Every project uses a modern stack: Next.js, TypeScript, headless CMS, and automated CI/CD. We deliver source code and full ownership.
- Uses Wordpress or Wix templates
- Charges hourly with no cap
- No automated testing
- Ships without CI/CD
- No performance budget
- You do not own the code
- Next.js + headless CMS
- Fixed price in 2 weeks
- Jest and Cypress in CI
- GitHub Actions, Vercel, Sentry
- Lighthouse score guaranteed above 90
- Full source code ownership
How we modernize your website in 4 phases
Our process moves from audit to launch in 8-12 weeks.
We start with a technical audit of your existing site. We identify performance bottlenecks, security gaps, and SEO issues. Then we create a detailed roadmap with milestones and a fixed price.
Each phase has defined deliverables. You see progress every week. We deploy to a staging environment before production launch. We run load tests and security scans before go-live.
What ships with every modernization project
You get more than a new front end. Here is the full delivery.
Every project delivers source code in your Git repository. No black box. You can take the code to any team after we finish.
We also ship documentation, deployment guides, and performance reports. Your internal team can maintain the site without us.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Vercel or AWS deployment configuration
- Sentry error tracking and performance monitoring
- SEO redirect map with 100% coverage
- Lighthouse performance report with scores above 90
- Automated test suite (Jest, Cypress)
- Content migration scripts
- Architecture decision record (ADR)
- Two-week post-launch support
What we ship in this practice.
Legacy travel booking site replatform
A 15-year-old travel booking site running on PHP and MySQL was crashing during peak traffic. We rebuilt the front end in Next.js with a headless CMS (Strapi) and added Redis caching. The site now handles 10x traffic with no downtime.
Ecommerce storefront migration to headless
A DTC brand with 5000+ SKUs moved from Shopify to a headless architecture using Next.js + Shopify Storefront API. Page load times dropped from 4s to 0.8s, increasing conversion rate by 22%. Fixed price $180K.
SaaS dashboard modernization
A B2B SaaS company had an AngularJS admin panel that took 8 seconds to load. We migrated to React with micro-frontends using Module Federation. Load time reduced to 1.2s. User engagement increased 35%.
Healthcare patient portal rebuild
A hospital network needed a HIPAA-compliant patient portal. We rebuilt the front end in Next.js with Auth0 for authentication and hosted on AWS with encryption. Searchable patient records now load in under 2 seconds.
Media site performance overhaul
A news publisher with 50 million monthly visitors had Core Web Vitals failing. We moved their article pages to Next.js ISR and added a CDN. Cumulative Layout Shift dropped to 0.01 and ad revenue increased 15%.
Manufacturing corporate site upgrade
A manufacturing company's Joomla site was hacked twice. We rebuilt with Next.js and Strapi, added WAF and DDoS protection on Cloudflare. Zero security incidents in two years. Site load time under 1 second.
Why teams hire us.
Senior engineers only, no juniors
Every IRPR project is staffed with engineers who have 8+ years of experience. We never outsource or hire juniors. Your code is written by people who have shipped to production hundreds of times.
Fixed price, no hourly billing
We give you a fixed price in the roadmap phase (week 2). There are no surprises. Our 200+ projects have a 98% on-time delivery rate.
You own every line of code
We put all source code in your private GitHub repo from day one. You can continue with any team after launch. There are no licensing fees or lock-in.
Modern stack by default
We use Next.js (React framework used by 10 million sites), Sanity or Strapi for headless CMS, and Vercel or AWS for hosting. No proprietary frameworks.
Performance is guaranteed
We set a Lighthouse performance budget and test every PR. Your site must score 90+ on mobile and desktop before launch. We include Sentry and Datadog monitoring.
Compliance built in from day one
We have built HIPAA-compliant portals, PCI-DSS ecommerce sites, and SOC 2 SaaS platforms. We include security headers, HTTPS enforcement, and audit logging by default.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
