Experienced Website Modernization TeamModernization Team
We modernize legacy websites in 8-12 weeks. Fixed price, senior engineers, no scope creep.
IRPR modernizes legacy codebases to React, Next.js, and Node.js stacks. We handle everything from jQuery/ASP.NET migrations to headless CMS rearchitecture.
Projects ship in 8-12 weeks. Typical cost is $80K to $250K. We handle compliance for PCI-DSS, HIPAA, SOC 2, and FERPA. You get source code ownership and a CI/CD pipeline.
We work with CTOs of mid-market companies whose legacy sites are slow, Product directors at SaaS firms needing a platform overhaul, eCommerce VPs migrating from Magento 1 to Shopify or custom, and Media executives wanting to decouple their CMS and improve page speed.
Types of software we ship.

Why experience matters in website modernization
Modernizing a website without breaking business continuity requires senior engineers who have done it before.
IRPR has completed 200+ website modernization projects across 50 countries. Our engineers have worked with stacks from jQuery and ASP.NET to React and Go. We know the edge cases that cause downtime.
Every project includes a thorough audit phase. We identify every dependency, API endpoint, and database trigger before writing a single line of new code. This de-risks the migration and keeps your site live during the transition.
Fixed price vs. hourly billing
Most agencies charge by the hour and change scope. We don't.
IRPR provides a fixed price after a 2-week Roadmap phase. You know the exact cost before development starts. No hourly billing, no surprise invoices.
Generic dev shops often assign junior developers to keep costs low. IRPR assigns only senior engineers with 10+ years of experience. You get better code, faster delivery, and no hidden fees.

Our website modernization process
We follow a structured 4-phase process to modernize your site without downtime.
Phase 1 is the Audit and Roadmap. We analyze your existing codebase, performance metrics, and security posture. You receive a fixed-price plan for the full modernization.
Phases 2 and 3 cover architecture design and parallel deployment. We build the new system alongside the old one, then migrate traffic gradually. Phase 4 is launch and handoff.
