Expert Website Modernization ServicesWebsite Modernization
We rebuild your legacy site into a fast, secure, revenue-driving platform. Fixed price, delivered in 8-12 weeks.
IRPR delivers expert website modernization services for businesses stuck on slow, outdated platforms. We replace custom PHP, jQuery, or monolithic CMS with React, Next.js, and headless architectures that load under 2 seconds.
Every project ships in 8-12 weeks at a fixed price between $80,000 and $250,000. You get a production-ready site with CI/CD pipelines, automated testing, Sentry error tracking, and full code ownership.
Who hires us: marketing directors whose conversion rate is falling because of page speed; CTOs who need to deprecate a legacy ColdFusion or Java monolith; ecommerce owners demanding PCI-compliant storefronts; and SaaS founders who want a server-side rendered front-end that their product team can extend.
Types of software we ship.
Front-end framework migration
Rebuild Angular 1, Backbone, or jQuery front-ends in React or Next.js with automated visual regression tests via Percy.
Headless CMS migration
Replace WordPress or Sitecore with Contentful, Strapi, or Sanity for decoupled editing and faster page load.
Legacy monolith to micro-frontends
Decompose a single Rails or Django app into isolated, independently deployable front-end modules using Module Federation.

Why modernize your website now
A slow, outdated site costs you money every day in lost conversions, higher hosting, and security risk.
Google uses Core Web Vitals as a ranking signal since 2021. Sites that load in under 2.5 seconds see 32% higher conversion rates. Our modernized sites achieve Lighthouse scores of 95+ across performance, accessibility, and SEO.
Legacy platforms like PHP 5, jQuery, or old Shopify themes have known vulnerabilities. IRPR partners with security teams to patch or replace these stacks entirely, targeting PCI-DSS compliance for ecommerce and HiTrust for healthcare. Every project includes a Web Application Firewall (Cloudflare or AWS Shield) as standard.
IRPR vs a generic dev shop
Most agencies bill hourly, over-promise, and hand off messy code. We do the opposite.
A generic dev shop often starts with a discover phase that lasts 4-6 weeks and then quotes hourly rates with no ceiling. They hand over files and walk away. You own technical debt and a fragile site.
IRPR writes a fixed-price Roadmap in week 2. You see exactly what ships, when, and at what cost. We test every PR with Cypress, monitor with Sentry and Datadog, and deploy via GitHub Actions. Code is yours from day one.
- Hourly billing with uncertain totals
- 6-week discovery phase before any code
- No automated testing or CI/CD
- CMS lock-in (WordPress, Sitecore)
- No performance budget defined
- Code ownership often disputed
- Fixed price agreed in week 2
- Ships production code by week 3
- Cypress CI, Sentry, Datadog monitoring
- Headless CMS (Contentful, Strapi, Sanity)
- Core Web Vitals targets written into contract
- 100% code ownership, no license fees
Our modernization process: 4 phases
From audit to deploy, every project follows the same predictable cycle.
Phase 1 (Weeks 1-2): Audit and Roadmap. We load-test your existing site, run Lighthouse and GTmetrix, and interview your team. Output: a fixed-price Roadmap with timeline, dependencies, and acceptance criteria.
Phase 2 (Weeks 3-6): Build. Senior engineers rewrite the chosen pages or modules in Next.js or a headless stack. Every PR passes automated tests. You see a staging environment by week 4.
What ships with every modernization
You get more than a new site. You get a production-ready system with no hidden setup steps.
Every IRPR modernization project ships with source code in your GitHub repo, a CI/CD pipeline with automated tests, a deployment to a live staging environment, and a monitoring stack. No extra fees for setup or configuration.
We also include a one-week warranty period post-launch where the team watches logs, fixes any critical bugs, and trains your content editors if we added a new CMS.
- Source code in your GitHub repository
- CI/CD pipeline using GitHub Actions
- Automated end-to-end tests with Cypress
- Error tracking via Sentry
- Performance monitoring via Datadog
- Web Application Firewall (Cloudflare or AWS Shield)
- Headless CMS setup (Contentful, Strapi, or Sanity)
- One-week post-launch warranty and support
- Architecture decision record (ADR) document
- Deployment runbook and rollback procedure
What we ship in this practice.
Ecommerce site migration from Magento 1 to headless Next.js
A fashion retailer with 5,000 SKUs migrated from unsupported Magento 1 to Next.js with GraphQL. Page load dropped from 6s to 1.8s. Conversion rate increased 22% in 3 months. Stack: Next.js, Sanity, Stripe, Vercel.
Legacy Rails monolith to micro-frontends
A B2B SaaS company serving 200+ enterprise clients replaced a Rails 4 monolith with isolated React micro-frontends. Deploy frequency went from weekly to 5x per day. Stack: React, Module Federation, AWS Fargate.
WordPress site to headless CMS for a media publisher
A regional news outlet with 2M monthly visitors moved from WP to Contentful + Next.js. Server costs fell by 55%. Core Web Vitals passed on all 3 metrics. Stack: Next.js, Contentful, Firebase hosting.
Patient portal upgrade for a healthcare network
A 5-clinic healthcare group replaced a ColdFusion patient portal with a HIPAA-compliant React app. Patient appointment requests reduced manual data entry by 8 hours per week per clinic. Stack: React, GraphQL, AWS ECS, HiTrust certified.
Fintech dashboard modernization for a lending startup
A lending platform with $50M in annual originations rebuilt its borrower dashboard from AngularJS to Vue 3. Loan application completion time dropped 40%. Stack: Vue 3, Stripe Connect, AWS Lambda, SOC 2.
Real estate MLS portal performance overhaul
A regional MLS aggregator serving 10,000 agents replaced its jQuery-based listing search with Next.js static generation. Search results loaded in 0.9s, up from 4.2s. Stack: Next.js, Algolia, Mapbox, Vercel.
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 budget before we write code.
Senior engineers only
IRPR does not hire junior developers. Every engineer has 10+ years of experience. The project manager is also a senior engineer. You never pay for ramp-up time.
Headless architecture by default
We never ship a monolithic CMS unless it's required. Default stack is Next.js + a headless CMS (Contentful, Strapi, Sanity). You get faster pages, easier editing, and better security.
Performance budget in the contract
We write your Core Web Vitals targets (LCP under 2.5s, FID under 100ms) as acceptance criteria. If the site doesn't hit those numbers, we fix it at no extra cost.
Full code ownership
You own the source code, the test suite, the CI/CD pipeline, and all documentation. No proprietary frameworks, no license fees, no vendor lock-in. Your team can take over anytime.
We ship in 8-12 weeks
Our process is designed for speed. The Roadmap phase takes 2 weeks. The build phase runs 6-10 weeks. You see a working staging environment by week 4. We have delivered 200+ projects on this cycle.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
