Best Legacy Website Modernization DevelopersWebsite Modernization
We rebuild outdated platforms in 12 weeks. IRPR ships modern, secure code that runs 2x faster.
IRPR rebuilds legacy websites using modern stacks like React 18, Next.js 14, and Node.js 20. We replace old jQuery, PHP 5, or Drupal 7 code with maintainable TypeScript, automated CI/CD pipelines, and cloud infrastructure on AWS or GCP.
Every modernization ships within 12-14 weeks at a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance so you can migrate without regulatory risk. The code goes to your repo on day one.
CTOs at enterprises with 10-year-old PHP sites hire us to reduce tech debt. Product managers at SaaS companies need to migrate from monolithic Rails to a headless architecture. Startup founders acquire legacy platforms and require a full refactor before scaling.
Types of software we ship.
Custom React rebuild
Replace jQuery or AngularJS with React 18. Ships with TypeScript, Jest tests, and a component library like Material-UI.
Headless CMS migration
Move from WordPress or Drupal to Strapi, Contentful, or Sanity. API-first design with Next.js frontend.
API layer extraction
Extract business logic from legacy monoliths into REST or GraphQL APIs. Uses Apollo Client and Express.
Monolith to microservices
Decompose a PHP or Java monolith into independent Node.js services with Docker and Kubernetes.
PHP to Node.js migration
Port Laravel or CodeIgniter codebases to Node.js with Express or NestJS. Uses TypeScript and Prisma ORM.
Static site generation
Convert dynamic WordPress to static Next.js sites deployed on Vercel or AWS S3. Reduces page load by 80%.
Database migration
Move from MySQL 5.7 to PostgreSQL 16 or migrate to MongoDB Atlas. Data integrity checks with Flyway.
Cloud migration
Lift-and-shift or refactor from on-premise to AWS/GCP. Uses Terraform for infrastructure as code.
We build for every business type.

What IRPR delivers for legacy website modernization
Every project includes measurable performance gains and a future-proof codebase.
IRPR has shipped over 200 products, and 60% of those involved modernizing an existing platform. We use tools like Lighthouse CI to benchmark before and after performance. Typical improvements: 50-80% faster load times, 90% better Core Web Vitals scores, and zero regression on accessibility.
Our fixed-price model means no surprises. During the Roadmap phase (week 2), we examine every line of your legacy code, identify bottlenecks, and provide a detailed quote. On average, modernization projects take 12 weeks and cost $80K-$250K.
Why generic dev shops fail at legacy modernization
Most agencies treat a legacy rebuild as a rewrite. IRPR treats it as a science.
Generic dev shops often charge by the hour with no fixed scope. They miss compliance requirements, skip performance baselines, and leave you with a half-refactored codebase that still uses old patterns. IRPR approaches each modernization with a strict process: document current state, isolate dependencies, ship incrementally.
We also handle compliance from day one. If your legacy site processes credit cards, we scope PCI-DSS requirements during Roadmap. If it handles patient data, HIPAA controls are built into the architecture. No surprise security audits.
- No fixed timeline - project drags 6-12 months
- Hourly billing encourages slow work
- No compliance expertise (HIPAA, PCI, SOC 2)
- Ships code without performance baselines
- Leaves legacy dependencies untouched
- No CI/CD pipeline setup
- Fixed 12-week timeline from Roadmap
- Fixed price - $80K to $250K
- HIPAA, PCI-DSS, SOC 2, FERPA built in
- Lighthouse CI benchmark before and after
- Full dependency audit and upgrade plan
- GitHub Actions CI/CD + Sentry monitoring
Our 4-phase legacy modernization process
We break the project into four clear phases with milestones and deliverables.
Phase 1 (Discovery) takes 1 week. We audit your codebase, map dependencies, run Lighthouse reports, and identify compliance gaps. Phase 2 (Roadmap) delivers a detailed plan with fixed pricing by week 2.
Phase 3 (Build) runs 8-10 weeks. We migrate code in modules, test each block, and deploy behind feature flags to minimize downtime. Phase 4 (Release) includes load testing, final compliance review, and a 30-day stability guarantee.
What ships with every modernization
You own everything. No lock-in, no black boxes.
Every IRPR modernization project delivers a full codebase, documentation, and CI/CD pipeline. We use GitHub for source control and deploy to your own cloud account. You get admin access to every tool we use.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- Lighthouse CI report comparing before and after scores
- Infrastructure as code (Terraform) for AWS or GCP
- Unit test suite with >80% coverage (Jest, Cypress)
- Security scan report (OWASP ZAP, Snyk)
- Deployment playbook with rollback steps
- 30-day post-launch support SLA
What we ship in this practice.
Legacy PHP CRM to Next.js + GraphQL
A healthcare SaaS company needed to modernize a 15-year-old PHP CRM. IRPR rebuilt the frontend in Next.js 14 with a GraphQL API layer (Apollo). Reduced average page load from 8s to 1.2s and cut server costs by 40%. Tech stack: Next.js, Apollo, PostgreSQL, AWS Lambda.
Magento 1 to Headless Shopify Migration
An ecommerce brand with $15M annual revenue was stuck on Magento 1 with security risks. IRPR migrated catalog, customer data, and checkout to Shopify Storefront API with a React frontend. Conversion rate increased 18% due to faster product pages.
Drupal 7 News Site to Static Next.js
A media company publishing 200 articles daily needed faster mobile load times. IRPR rebuilt the site as a static Next.js site with incremental static regeneration. Lighthouse performance score jumped from 45 to 95. Deployed on Vercel with zero downtime.
Legacy .NET Loan Origination System
A fintech startup acquired a credit union's loan system written in .NET Framework 4.5. IRPR extracted business logic into Node.js microservices with a React UI. Processing time per application dropped from 24 hours to 3 minutes.
ColdFusion Admin Dashboard to React
A logistics company used a 20-year-old ColdFusion dashboard to manage 500+ trucks. IRPR rebuilt the UI in React with real-time tracking via WebSockets. Order lookup time went from 15 seconds to under 1 second. Used AWS AppSync and DynamoDB.
PHP 5 SaaS Platform to Laravel + Vue
A B2B SaaS for real estate agents ran on PHP 5 with no upgrade path. IRPR migrated to Laravel 11 with a Vue 3 frontend and PostgreSQL. Monthly uptime improved from 99.2% to 99.99%. Also achieved SOC 2 Type II certification for new code.
