Senior Website Modernization ConsultantsModernization Consultants
We rebuild legacy websites on modern stacks in 12-14 weeks. You get a faster, secure, maintainable platform with no technical debt.
IRPR builds modern websites from aging legacy platforms. We use Next.js, Sanity CMS, and AWS Lambda to replace outdated ASP.NET, Drupal, or WordPress sites. Every project ships with automated CI/CD and Sentry error tracking.
A full modernization takes 12-14 weeks and costs between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. The result is a fast, accessible static site with a headless CMS backend.
CTOs hire us when they need to replatform a 10-year-old site without downtime. VP of Engineering teams use us to migrate from monolithic to micro frontends. Product managers engage us to ship a redesign with measurable performance gains.
Types of software we ship.
Legacy site replatforming
Migrate monolithic ASP.NET or PHP sites to Next.js with headless CMS. Reduces server cost and page load time by 50%+.
Headless CMS migration
Replace WordPress or Drupal with Contentful or Sanity. Decouple content from presentation for faster publishing and omnichannel use.
Front-end architecture redesign
Refactor jQuery or AngularJS sites into React or Vue components. Improves code maintainability and developer velocity.
Performance optimization
Audit and improve Core Web Vitals. Implements lazy loading, code splitting, CDN caching to achieve Lighthouse scores above 90.
Accessibility remediation
Update sites to meet WCAG 2.1 AA/AAA. Adds ARIA labels, keyboard navigation, and screen reader support for compliance.
PWA conversion
Turn existing sites into Progressive Web Apps with offline support and push notifications. Increases mobile engagement by 30%.
API gateway integration
Add a GraphQL or REST API layer to existing sites. Enables seamless integration with CRM, payment, and analytics platforms.
Design system implementation
Build a reusable component library in Storybook with design tokens. Speeds up future feature development by 40%.
We build for every business type.
Enterprise SaaS platforms
High-traffic ecommerce stores
Healthcare patient portals
Media and publishing sites
Financial services platforms
Website modernization by the numbers
Our senior consultants deliver measurable improvements for every project.
Every website modernization we build is benchmarked against the previous version. We measure Page Speed Index, Time to Interactive, and Lighthouse accessibility scores before and after.
In our last 20 projects, average First Contentful Paint dropped from 3.2 seconds to 1.1 seconds. Security scan vulnerabilities went from 15 to 0. Monthly server costs decreased by 62% on average.
Why generic dev shops fail at modernization
Most agencies treat a website upgrade like a simple reskin. IRPR treats it as an architectural transformation.
Generic development shops often patch a legacy site with new CSS and call it modern. They skip the hard work of lifting and shifting core systems, leaving you with technical debt and slow page loads.
IRPR assigns senior engineers who have shipped 200+ modernizations. We write a full Roadmap in week 2 with fixed price. Every project ships with source code you own, a CI/CD pipeline, and documentation.
- Junior or mixed teams
- Hourly billing with creep
- Timeline slips 2-3 months
- No compliance expertise
- No CI/CD setup
- You don't own the code
- Senior engineers only
- Fixed price from Roadmap
- 12-14 week delivery
- HIPAA / PCI / SOC 2 ready
- GitHub Actions CI/CD included
- Full code ownership
Our website modernization process
Four phases that turn your legacy site into a modern platform.
Every project follows the same blueprint. We start with a discovery week, then deliver a Roadmap, build in 2-week sprints, and deploy with full documentation.
The process is designed for transparency. You see progress in a shared Jira board and review working prototypes every sprint.
What ships with every modernization
Every project delivers more than just a new website.
We don't hand over a build and walk away. IRPR gives you the complete toolkit to run and maintain your new site.
Your developers will get a repo with full commit history, a documented design system, and automated tests.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Staging and production environments on AWS or Vercel
- Sentry error monitoring and logging
- Lighthouse audit report (target 90+)
- Component library in Storybook
- API documentation with Swagger or GraphQL schema
- User migration script (if applicable)
- Admin training session (up to 2 hours)
What we ship in this practice.
Replatform legacy ecommerce to headless
Migrated a Magento 2 store to Next.js front end with ElasticPath headless commerce. Reduced page load time from 4.2s to 0.9s, increased mobile conversion by 34%. Stack: Next.js, ElasticPath, Vercel, Stripe.
Modernize healthcare patient portal
Rebuilt a 12-year-old ASP.NET portal with React and GraphQL. Achieved WCAG 2.1 AA compliance, cut time to book an appointment from 5 clicks to 2. Stack: React, Apollo, AWS Cognito, HIPAA-compliant hosting.
Upgrade media site for ad performance

Redesign fintech dashboard for compliance
Modernized a legacy AngularJS dashboard to React with TypeScript. Added real-time data via WebSockets and passed PCI-DSS audit with zero findings. Stack: React, Redux, WebSocket, Auth0.
Build PWA for real estate listings
Turned a slow WordPress site into a Progressive Web App with offline map access. Increased mobile engagement by 40% and saved 30% in server bandwidth. Stack: Next.js, Mapbox, IndexedDB, Firebase.
Optimize SaaS platform for global performance
Refactored a monolithic Rails app into a Next.js front end with API routes. Used CDN edge caching on CloudFront to reduce latency for users in Asia from 800ms to 120ms. Stack: Next.js, Rails API, CloudFront, Datadog.
Why teams hire us.
Fixed price from day one
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we build.
Senior engineers only
Every developer on your project has 8+ years of experience. We don't staff juniors or offshore. Our team has shipped modernizations for companies in 50+ countries.
Proven process with 4 phases
We follow the same 4-phase blueprint (Discovery, Roadmap, Product, Release) for every engagement. This process has been refined across 200+ projects and delivers on time 98% of the time.
Full code ownership
When the project ends, you get 100% ownership of all source code, documentation, and infrastructure. No licenses, no lock-in, no ongoing fees.
Start fast with a 1-2 week kickoff
Most projects begin within 2 weeks of signing. We schedule a 90-minute kickoff call, set up your Slack channel, and start Discovery immediately.
Compliance built in from the start
We handle HIPAA, PCI-DSS, SOC 2, and WCAG standards in every modernization. Our code review process includes a security checklist and automated SAST scans with tools like SonarQube.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
