affordable legacy website modernization developerswebsite modernization
We rebuild old, slow sites into modern web apps using Next.js and Node.js. Fixed-price projects from $80K, delivered in 8-12 weeks.
IRPR builds modern replacements for legacy websites using Next.js, Node.js, React, and PostgreSQL. We strip out old jQuery, PHP monoliths, or SharePoint sites and ship a faster, secure, maintainable app.
Each project starts at $80K and runs 8-12 weeks. We handle compliance needs like HIPAA for healthcare, PCI-DSS for ecommerce, and SOC 2 for SaaS. You get full ownership of source code and CI/CD pipelines.
We work with CTOs at companies stuck on a 10-year-old Drupal site who need a rewrite. Product managers at fintech firms migrating from a legacy ASP.NET app. And founders of growing startups whose custom PHP site can no longer handle traffic or feature requests.

Legacy PHP to Next.js Migration
Replace old WordPress or custom PHP sites with a Next.js frontend and Node.js API. Faster load times and better security.
Legacy ASP.NET to React Rewrite

Affordable Legacy Website Modernization Developers by the Numbers
We have modernized over 200 websites and web apps for clients in 50+ countries.
Our team of senior engineers averages 10+ years of experience. We ship 98% of projects on time and on budget. Every rewrite goes through a 2-week Roadmap phase where we scope the work and lock the price.
Clients typically see 40-60% faster page load times after modernization. API response times drop from 1200ms to under 200ms. Security vulnerabilities from outdated libraries are eliminated.
Why Generic Dev Shops Fail at Modernizing Your Legacy Website
Most agencies treat modernization like a simple redesign. They miss data, security, and performance issues.
A generic dev shop often copies the old design into a new framework without fixing underlying problems. They may not handle database migrations, API rewrites, or third-party integration upgrades. Your new site might look modern but still break on edge cases.
IRPR treats every modernization as a full rebuild. We audit your existing code, database, and integrations during the Roadmap phase. We write automated tests for critical paths, set up CI/CD, and monitor performance. You get a site that is faster, more secure, and easier to maintain.
- Starts coding without a full audit
- Keeps old database schema as-is
- No performance baseline before migration
- Only updates frontend, ignores backend
- No CI/CD pipeline for deployments
- No post-launch monitoring or support
- 2-week Roadmap with full tech audit
- Database migration to PostgreSQL if needed
- Performance baseline and target KPIs
- Full stack rewrite: frontend, API, DB
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and uptime monitoring
How We Modernize Your Legacy Website in 4 Phases
Our process is designed to minimize risk and deliver a production-ready product fast.
Phase 1 audits your existing system. Phase 2 locks the scope and price. Phase 3 builds the new site. Phase 4 deploys and monitors.
You see progress every 2 weeks. We deploy to a staging environment for testing before going live.

What we ship in this practice.
Legacy PHP Booking System to Next.js
A healthcare clinic chain had a custom PHP booking portal that crashed daily. IRPR rebuilt it in Next.js with a Node.js API and PostgreSQL. Load time dropped from 8 seconds to 1.2 seconds. Uptime hit 99.9%. Patient bookings increased by 30%.
ASP.NET Insurance Portal to React
A fintech insurance aggregator ran on ASP.NET Web Forms from 2011. The site took 12 seconds to load quote results. IRPR migrated to React, Node.js, and MongoDB. Quote generation dropped to 2 seconds. Conversion rate improved by 25%.
Magento 1 to Headless Commerce
A B2B wholesaler was stuck on Magento 1 with no security patches. IRPR moved them to a headless stack: Next.js, MedusaJS, and Stripe. The new store handled 10x traffic during Black Friday. Order processing time dropped from 90 seconds to 12 seconds.
Legacy CRM Portal to Microservices
A SaaS company had a monolithic PHP CRM that could not scale. IRPR refactored it into microservices with Node.js, PostgreSQL, and Redis. Response times dropped from 1500ms to 150ms. The team could deploy features 3x faster.
SharePoint Intranet to Custom React App
A manufacturing firm used SharePoint 2010 for their intranet. Employees complained about slow search and broken workflows. IRPR built a custom React app with Elasticsearch. Search results appeared in under 500ms. IT support tickets dropped by 40%.
Legacy Real Estate MLS Portal to Next.js
A real estate brokerage had an outdated MLS portal built on Ruby on Rails 2. IRPR rebuilt it in Next.js with a PostgreSQL backend and GraphQL API. Page loads went from 6 seconds to 0.8 seconds. Agent satisfaction scores increased by 35%.
Why teams hire us.
Fixed Price, Not Hourly
Every legacy modernization project gets a fixed quote after the 1-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
