Legacy Website Modernization ConsultantsModernization Consultants
We rebuild your old website into a fast, secure, scalable platform. Fixed price, senior engineers, full code ownership.
IRPR is a team of senior engineers who specialize in legacy website modernization. We replace outdated codebases (PHP, jQuery, ASP.NET, Flash) with modern stacks like Next.js, React, Node.js, and headless CMS platforms such as Strapi or Contentful.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code, CI/CD pipelines, and a 99.9% uptime SLA.
We work with CTOs at mid-market companies who need to migrate off unsupported platforms, product owners at SaaS firms who want to reduce page load times by 60%, and digital directors at healthcare organizations who must meet HIPAA requirements while modernizing their patient portal.
Types of software we ship.
Legacy PHP to React Migration

Why legacy website modernization matters
Old websites cost you money in slow load times, security risks, and lost conversions.
A legacy website built on outdated frameworks like jQuery or ASP.NET can load 3-5 seconds slower than a modern React or Next.js site. That extra second costs ecommerce sites 7% in conversions. For a site doing $1M monthly, that is $70K lost every month.
Security vulnerabilities in unsupported platforms like PHP 5.x or Flash are a direct compliance risk. HIPAA and PCI-DSS audits flag these systems. IRPR replaces them with secure, auditable codebases that pass any compliance review.
Generic dev shop vs IRPR
Not all agencies deliver a modern, secure, and scalable website.
Many dev shops quote hourly rates, use junior developers, and hand over code with no documentation. You end up with a new site that still has performance issues and security gaps.
IRPR assigns senior engineers only, gives a fixed price upfront, and delivers a fully documented codebase with CI/CD, monitoring, and a 99.9% uptime guarantee.
- Hourly billing with no cap
- Junior developers learning on your project
- No compliance expertise (HIPAA, PCI-DSS)
- No CI/CD or automated testing
- Code ownership unclear
- No post-launch support
- Fixed price from $80K to $250K
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 compliance built in
- CI/CD pipeline with GitHub Actions and Sentry
- Full source code ownership
- 12-month warranty and 99.9% uptime SLA
Our 4-phase modernization process
We follow a structured process from audit to launch.
Every project starts with a 2-week audit of your existing codebase, infrastructure, and performance. We identify bottlenecks, security gaps, and compliance issues.
Then we build a detailed roadmap, execute the migration in sprints, and deploy with zero downtime. You get a modern, fast, and secure website in 8-12 weeks.

You own everything. No black boxes.
When IRPR modernizes your website, you get more than just new code. You get a complete, production-ready system with all the tools your team needs to maintain and scale it.
Every project includes documentation, automated tests, and a deployment pipeline. Your internal team can take over immediately or we can continue to support.
- Full source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and automated tests
- Sentry error tracking and performance monitoring
- Docker containers for local development and production
- Database migration scripts with rollback support
- Load testing report with 99.9% uptime verification
- Security audit report (OWASP Top 10)
- Deployment runbook and architecture documentation
- 12-month warranty with 4-hour response SLA

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 cost before we write a line of code.
Senior engineers only
We do not use junior developers. Every engineer on your project has 10+ years of experience and has shipped at least 20 production applications. You get a lead architect, a frontend specialist, and a DevOps engineer.
Compliance built in
We have built HIPAA-compliant patient portals, PCI-DSS payment systems, and SOC 2 audited SaaS platforms. Compliance is not an afterthought. It is part of our development process from day one.
Full code ownership
You own every line of code we write. No proprietary frameworks, no locked-in platforms. We put the source code in your GitHub repo and give you full admin access. You can take it anywhere.
8-12 week delivery
Most legacy modernization projects take 6-12 months at other agencies. IRPR delivers in 8-12 weeks because we use proven patterns, automated testing, and senior engineers who do not need ramp-up time.
Post-launch warranty
Every project includes a 12-month warranty with a 4-hour response SLA. If something breaks, we fix it. No additional cost. We also provide optional ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
