Premium Website Modernization StudioWebsite Modernization
We rebuild legacy sites into modern, fast, secure web applications. Delivered in 8-12 weeks with fixed pricing.
IRPR modernizes outdated websites using React, Next.js, and headless CMS platforms like Strapi or Sanity. We replace legacy jQuery, PHP, or monolithic CMS with component-based, server-rendered architectures that score 90+ on Google Lighthouse.
Every project ships in 8-12 weeks with a complete frontend rebuild, REST/GraphQL API layer, automated CI/CD pipeline on GitHub Actions, and accessibility compliance (WCAG 2.1 AA). Pricing is fixed from $80K to $250K depending on page count and integrations.
CTOs of enterprises with legacy platforms hire us to reduce technical debt. Marketing directors want faster load times and better SEO. Product owners need new features without rebuilding from scratch. Startups acquiring mature platforms need scalable modern frontends.
Types of software we ship.
Legacy to React Migration
Rebuild jQuery or AngularJS apps in React with component reusability and type safety via TypeScript. Typically 10-30 pages.
Static Site to Headless CMS
Convert flat HTML sites to a headless CMS like Contentful or Strapi, enabling dynamic content management without touching the frontend.
Monolith to Micro-Frontend
Split a single-page app into micro-frontends using Module Federation, allowing independent deployment of features by different teams.
jQuery to Vue.js
Replace jQuery spaghetti with Vue.js components, using Pinia for state management and Vite for fast builds under 2 seconds.
Custom WordPress to Next.js
Keep WordPress as a headless CMS while rendering content with Next.js, improving TTFB by 50% and eliminating plugin bloat.
Server-Rendered to JAMstack
Move from PHP/Java server rendering to JAMstack with Next.js static generation, hosted on Vercel with instant cache invalidation.
E-commerce Platform Modernization
Modernize Magento or Shopify themes using Next.js Commerce and Stripe, achieving sub-second product page loads and 99.9% cart uptime.
Enterprise Portal Modernization
Replace SharePoint or Oracle portals with React dashboards, integrating Okta SSO and a GraphQL back end for real-time data feeds.
We build for every business type.
Why choose IRPR for website modernization
Every modernization project ships with measurable improvements in performance, security, maintainability, and user experience.
Our team has completed 200+ product builds across 50 countries. We use the same process for modernization: we audit your codebase in week 1, produce a detailed roadmap in week 2, then build in 2-week sprints with daily pull requests and continuous deployment.
Clients see 40-60% faster load times, a 90+ Lighthouse score, and zero security vulnerabilities in the OWASP Top 10 after migration. All projects include automated accessibility audits (axe-core) and cross-browser testing (Playwright).
How IRPR differs from generic development shops
Most agencies treat modernization as a rewrite. IRPR treats it as a surgical upgrade with zero downtime.
Generic shops often start coding without a clear roadmap, leading to scope creep and missed deadlines. They may also keep code ownership ambiguous and charge by the hour, making budgets unpredictable.
IRPR provides a fixed price after a 2-week Roadmap phase, grants full code ownership from day one, and ships with CI/CD, error tracking (Sentry), and performance monitoring (Datadog) built in.
- Hourly billing with no price cap
- No roadmap before coding starts
- Code remains on agency servers
- No CI/CD or automated testing included
- Junior developers on your project
- 6-12 month timelines typical
- Fixed price locked after Roadmap phase
- Detailed project roadmap in week 2
- Full code ownership in your GitHub repo
- CI/CD pipeline with automated tests shipped
- Senior engineers only (8+ years average)
- 8-12 week delivery guaranteed
Our 4-phase modernization process
We follow a structured process from audit to launch, ensuring no surprises for your budget or timeline.
Phase 1: Audit. We run a full code analysis (Lighthouse, WebPageTest, security scan) and produce a report with findings and recommendations. Phase 2: Roadmap. We create a detailed plan with page-by-page migration strategy, API design, and QA checklist.
Phase 3: Build. Senior engineers implement the new frontend in React or Next.js, integrating with your existing backend or a new headless CMS. Phase 4: Release. We deploy with a blue-green strategy, run load tests, and hand over documentation.
What ships with every modernization project
We don't just deliver a new website. We deliver a complete production system that your team can own and extend immediately.
Every project includes a fully configured CI/CD pipeline, automated testing for accessibility (axe-core) and visual regression (Percy), and monitoring with Sentry and Datadog. You get a private npm package or monorepo with reusable components.
Documentation covers architecture decisions, API endpoints, component library usage, and deployment runbooks. We also provide a 30-minute walkthrough session for your developers.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and Datadog performance monitoring
- Google Lighthouse report showing 90+ score
- WCAG 2.1 AA accessibility audit report
- Playwright cross-browser test suite
- Headless CMS setup (Strapi, Sanity, or Contentful)
- Deployment on Vercel, Netlify, or AWS (your choice)
- Architecture decision record (ADR) document
- 30-day post-launch support window

Fixed price, not hourly
Every modernization project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price covers everything from audit to deployment.
Full code ownership from day one
All source code is stored in your private GitHub repository from the first commit. We never lock you in to proprietary hosting or licensing. You own the entire codebase.
8-12 week delivery guarantee
Our average project length is 10 weeks. We structure every modernization into 6 sprints max. If a project is delayed beyond 12 weeks by our team, we reduce the final invoice by 20%.
Senior engineers only
Every developer on your project has at least 8 years of experience building frontend systems. No junior or offshore teams. We have 200+ product ships among our senior engineers.
Post-launch support included
We include 30 days of post-launch monitoring and support. This covers bug fixes, performance tuning, and any immediate adjustments based on your team's feedback.
Compliance built in, not bolted on
We build accessibility (WCAG 2.1 AA) and security (OWASP Top 10) into every sprint. Our audit phase includes a full compliance gap analysis and remediation plan.
