Legacy Website Modernization FirmModernization Firm
Your old site costs you time and money. We rebuild it on modern tech with a fixed price and a 12-week timeline.
IRPR is a legacy website modernization firm. We take old PHP, jQuery, or ASP.NET sites and rebuild them on modern stacks like Next.js, React, and Node.js. We keep your data, your SEO, and your business logic -- we just make everything faster and more secure.
Every project ships in 12 weeks or less. Fixed pricing starts at $80K and goes to $250K depending on scope. We handle compliance like HIPAA, PCI-DSS, and SOC 2. You get a new site with CI/CD, automated testing, and full documentation.
We work with CTOs whose legacy platform is breaking under traffic. We work with VPs of Engineering whose team cannot maintain the old code. We work with founders who need to modernize before a Series A audit. We work with IT directors who need to deprecate a custom CMS.

Why you need a legacy website modernization firm
Outdated websites cost you money, security, and customers.
A legacy site built on PHP 5.x or jQuery 1.x cannot handle modern traffic loads. It has known security vulnerabilities. It loads slowly on mobile. Google penalizes slow sites in search rankings. A modernization project fixes all of these problems at once.
IRPR has modernized 200+ legacy systems across 50 countries. We use Next.js for frontend, Node.js for APIs, and PostgreSQL for data. Every project includes a CI/CD pipeline on GitHub Actions and error monitoring with Sentry. You own the code from day one.
How IRPR is different from other firms
Most dev shops charge by the hour and miss deadlines. IRPR does the opposite.
Generic agencies bill hourly and have no incentive to finish fast. They use junior developers who do not understand legacy code. They deliver a new site that still has performance problems. They hand over a tarball with no documentation.
IRPR assigns senior engineers only. Every project has a fixed price agreed in week 2. We ship a modern site with full CI/CD, automated tests, and a deployment runbook. We stay on the project for 30 days after launch to handle issues.
- Hourly billing with no cap
- Junior devs working on your production code
- No CI/CD pipeline delivered
- Ships a single zip file with no docs
- No performance testing or load testing
- Disappears after launch
- Fixed price from week 2
- Senior engineers with 10+ years experience
- CI/CD on GitHub Actions included
- Full documentation and deployment runbook
- Load testing with k6 and Lighthouse audits
- 30-day post-launch support included
Our 4-phase legacy modernization process
We turn your old site into a modern platform in 12 weeks.
Phase 1 is the Idea phase. We audit your existing codebase, database schema, and hosting setup. We identify all third-party integrations and data dependencies. We produce a migration plan with a timeline and fixed price.
Phase 2 is the Roadmap. We design the new architecture, select the tech stack, and set up the CI/CD pipeline. We get sign-off on wireframes and data migration strategy. This phase takes 2 weeks.
What ships with every modernization project
You get a complete, production-ready system -- not just a new frontend.
Every project includes a fully automated deployment pipeline. We set up staging and production environments on AWS or Vercel. We configure error tracking, performance monitoring, and database backups. You can deploy a new version with one git push.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated test suite (unit + integration + e2e)
- Sentry error tracking and performance monitoring
- Lighthouse score report with performance targets
- Data migration scripts and rollback plan
- Deployment runbook with environment variables
- Post-launch support for 30 days
- Full API documentation (Swagger or Postman)
- Load test results from k6 with 1000 concurrent users

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of production code.
Senior engineers only
We do not staff junior developers. Every engineer on your project has 10+ years of experience. They have shipped modernizations for healthcare, fintech, and ecommerce systems.
12-week timeline guarantee
We ship every modernization project in 12 weeks or less. Our 4-phase process keeps the team focused. We have a 98% on-time delivery rate across 200+ projects.
Full code ownership
You own the entire codebase from day one. We put the source code in your GitHub repo. There is no licensing fee, no vendor lock-in, no recurring royalty.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, FERPA, and ISO 9001 compliance as part of the project. We configure encryption, access controls, and audit logging. Your compliance audit passes on the first try.
Post-launch support included
We stay on the project for 30 days after launch. We monitor Sentry errors, respond to incidents, and fix bugs. You get a smooth transition without hiring a new team immediately.
