Expert Website Modernization VendorModernization Vendor
We rebuild your legacy site on modern tech stacks. Your team ships faster and users get a faster site.
IRPR is an expert website modernization vendor that rebuilds legacy sites on React, Next.js, or any modern framework. We replace old PHP, jQuery, or monolithic CMS with a component-based architecture.
Every project has a fixed price defined in the Roadmap phase (week 2). Timeline is 12-14 weeks for most sites. Budget ranges from $80K to $250K depending on pages, integrations, and data migration. We handle compliance like PCI-DSS for ecommerce and HIPAA for healthcare.
We work with CTOs at mid-market companies who are stuck on a legacy codebase that is slow and insecure. Product managers who need to ship new features faster without breaking the site. Marketing directors who want a headless CMS to push content faster.
Types of software we ship.
Legacy PHP to React migration
Replace old PHP monolith with a React SPA. Migrate templates, forms, and authentication to a component library.
jQuery to Vue.js refactor
Replace jQuery spaghetti with Vue.js components. All event handlers, DOM manipulation, and AJAX calls become clean reactive code.
Monolithic CMS to headless CMS
Move from Drupal or WordPress to Contentful or Strapi. Keep the admin panel. Rebuild the frontend with Next.js for faster page loads.
Server-rendered to Jamstack
Rebuild your server-rendered Rails or Django site on a Jamstack architecture with Astro or Next.js static generation. No server overhead for marketing pages.
Ecommerce platform upgrade
Upgrade Magento 1 to Magento 2 or migrate to Shopify Plus / BigCommerce. Preserve product catalog, order history, and SEO rankings during cutover.
Angular to React migration
Rewrite AngularJS (1.x) applications to React with TypeScript. Preserve business logic, routing, and state management during a phased migration.
API modernization with GraphQL
Replace REST endpoints with a GraphQL layer using Apollo or Hasura. Reduce frontend calls from 10+ requests to 1 query per page view.
Legacy .NET to Node.js migration
Rebuild .NET Web Forms or MVC apps on Express.js or Fastify. Migrate business logic, database access, and session management to modern Node patterns.
We build for every business type.

What an expert website modernization vendor delivers
We rebuild your site from legacy code to modern architecture in 12 weeks.
IRPR has shipped 200+ modernized sites across 50 countries. Every project starts with a technical audit of your existing codebase. We identify deprecated libraries, security gaps, and performance bottlenecks. For example, we found a Magento 1 site using jQuery 1.7 with 12 known CVEs. We migrated it to Shopify Plus with a Next.js frontend in 11 weeks.
Our team uses React, Next.js, and headless CMS tools like Contentful or Stellar. Each migration includes automated testing with Cypress and Playwright. We deploy on Vercel or AWS with CI/CD pipelines on GitHub Actions. The result: a 40-60% reduction in page load time and a CMS your content team can actually use.
Generic dev shops vs. IRPR as your expert website modernization vendor
Most agencies sell you a rewrite and disappear after launch. We build a foundation for your next 5 years.
A typical web dev agency quotes hourly rates and writes vague scopes. They deliver a design that looks new but uses the same old jQuery and inline CSS. Security patches and performance optimization are never part of the agreement.
IRPR works differently. We quote a fixed price after a 2-week Roadmap phase where we audit your entire codebase, define the target architecture, and write acceptance tests. Everything is in writing before we write a single line of code. You get full code ownership and a CI/CD pipeline that keeps your team shipping fast.
- hourly billing with no cap
- vague scope documents
- no performance baseline
- old tech stack (jQuery, Bootstrap)
- no accessibility audit
- no CI/CD handoff
- fixed price after week 2
- detailed technical Roadmap
- performance budget defined upfront
- modern stack (React, Next.js, TypeScript)
- WCAG 2.1 AA compliance audit
- GitHub Actions pipeline included
Our 4-phase modernization process
Every website modernization at IRPR follows a repeatable 4-phase process.
Phase 1 (Idea) is a discovery week. We review your analytics, current tech stack, and business goals. We identify quick wins like unminified assets, missing cache headers, and outdated dependencies. The output is a prioritized list of issues and opportunities.
Phase 2 (Roadmap) is the second week. We define the target architecture, select tools (e.g., Next.js, Contentful, Sanity), create a migration plan for content and data, and write acceptance tests. You get a fixed price, a timeline table, and a risk register. No surprises later.
What ships with every modernization project
You own everything. No black boxes. No proprietary frameworks.
Every IRPR modernization project delivers a full tech transfer. You get the source code (Git repo with full history), architecture diagrams (draw.io), a CI/CD pipeline on GitHub Actions, a staging environment on Vercel, and documentation for your content team. We also set up Sentry for error tracking and Google Lighthouse for performance monitoring.
Your internal team can start making changes on day one after release. We include a 2-week support window post-launch to handle bugs and answer questions. If you need ongoing development, we can extend the engagement monthly or quarterly.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Staging environment on Vercel or AWS
- Architecture diagrams (draw.io)
- Content migration scripts
- Sentry error tracking set up
- Lighthouse performance baseline report
- WCAG 2.1 AA audit report
- CMS admin guide for your team
- 2-week post-launch support
What we ship in this practice.
Magento 1 to Shopify Plus migration
A fashion retailer with 50,000 products was running Magento 1 with no security patches. IRPR migrated the entire catalog, customer accounts, and order history to Shopify Plus with a Next.js frontend. Page load time dropped from 6.2s to 1.8s. Revenue per visitor increased 22% in the first month.
Drupal 7 to headless CMS rebuild
A B2B SaaS company needed a faster marketing site and a better content editor experience. IRPR rebuilt their 200-page site on Next.js with Contentful as the headless CMS. The marketing team could push new pages in hours instead of days. Site speed improved from 4.5s to 1.2s.
jQuery app rebrand to React PWA
A news media company had a legacy jQuery-based website that was not responsive and failed Google Core Web Vitals. IRPR rewrote it as a React PWA with server-side rendering on Next.js. Time to interactive went from 10s to 2.3s. Mobile traffic increased 35% within 8 weeks.
AngularJS to React migration for a dental network
A 50-location dental practice had an AngularJS patient portal that was slow and hard to maintain. IRPR migrated all components to React with TypeScript and connected it to a new GraphQL layer. Patient checkout time dropped from 12 minutes to 3 minutes. Staff satisfaction scores improved 40%.
Rails ecommerce to Jamstack rebuild
An outdoor gear retailer had a Ruby on Rails store that could not handle Black Friday traffic. IRPR rebuilt the frontend with Astro and hosted it on Netlify. The site served 95% of pages from CDN cache. Black Friday sales doubled with zero downtime.
Legacy .NET campus portal to Node.js migration
A university with 30,000 students had a .NET Web Forms portal that crashed every semester during registration. IRPR rewrote the backend in Node.js with Express and a GraphQL API. Registration capacity went from 500 to 5,000 concurrent users. System uptime stayed at 99.9% for the full semester.
Why teams hire us.
Fixed price, not hourly
Every modernization project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we start building.
Senior engineers only
Every IRPR engineer has 10+ years of experience. We do not outsource to junior devs or offshore teams. Your project is handled by engineers who have shipped 200+ products.
Full code ownership from day one
The source code lives in your GitHub repo from the first commit. We never use proprietary frameworks or lock-in tools. You can take the code to any team after launch.
Performance budget included
Every project includes a Lighthouse performance budget (e.g., LCP under 2.5s, TBT under 100ms). We test against these KPIs in every sprint. If the site does not meet the budget, we fix it before launch.
CI/CD pipeline ships with the project
We set up GitHub Actions with automated builds, linting, tests, and deployments. Your team can deploy to production with a single pull request. No manual FTP uploads ever.
Compliance built in from the start
If your site requires PCI-DSS, HIPAA, or SOC 2, we handle it during the Roadmap phase. We audit dependencies, set up logging, and configure encryption before we write the first component.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
