Website Modernization in Numbers
Our modernization projects deliver measurable improvements across performance, security, and cost.
We track every project against baseline metrics. On average, modernized sites reduce page load time by 60% and increase organic traffic by 35% within 3 months.
Our clients save an average of $120K per year in hosting and maintenance costs after migrating from legacy infrastructure to cloud-native stacks.
Why Most Modernization Projects Fail
Generic dev shops rush migrations without planning for SEO, compliance, or performance.
A typical agency rewrites everything from scratch, breaking existing URLs and causing a 40% traffic drop. They also ignore accessibility requirements until launch, adding 3+ months of remediation.
IRPR preserves your SEO value, maps every URL, and validates accessibility (WCAG 2.1 AA) in the first sprint. We also containerize your existing database so there's zero downtime during migration.
- Rewrites from scratch, breaking SEO
- No URL mapping – traffic drops 40%
- Ignores accessibility until launch
- No compliance review (HIPAA/PCI)
- Hourly billing with creeping scope
- No performance baseline or guarantee
- Preserves SEO with 301 redirects and structured data
- Maintains all existing URLs and page rankings
- Ships WCAG 2.1 AA accessibility by sprint 1
- Includes HIPAA/PCI/SOC 2 compliance in scope
- Fixed price from the Roadmap phase (week 2)
- Sets performance baselines and guarantees 60% improvement
Our 4-Phase Modernization Process
From legacy audit to production release, we follow a structured roadmap.
Every project begins with a two-week Roadmap phase where we inventory your current codebase, CMS, hosting, and third-party integrations. We identify all risks and create a fixed-price plan.
The Product phase builds incrementally — we refactor one module at a time, deploy to staging daily, and run parallel tests against your old site to verify correctness.
Everything That Ships with Your Modernized Website
You own all code, infrastructure scripts, and documentation from day one.
We deliver a fully documented, deployment-ready repository with CI/CD pipelines, automated tests, and monitoring dashboards. There's no lock-in — you can take the project in-house at any point.
Every project includes a runbook that covers disaster recovery, scaling plan, and daily operations. Your ops team can manage everything without contacting us.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline using GitHub Actions with linting, tests, and auto-deploy
- Sentry error tracking and Datadog performance monitoring
- Automated Lighthouse CI with threshold gates (90+ performance, 90+ accessibility)
- SEO redirect map (301s) for all legacy URLs
- Infrastructure-as-code (Terraform or Pulumi) for AWS/GCP/Azure
- Post-deployment load tests (Artillery or k6) showing 10x concurrent user capacity
- Runbook with backup procedures, scaling triggers, and incident response
- Admin dashboard for non-technical editors (headless CMS or custom)
- Accessibility audit report (WCAG 2.1 AA pass/fail per page)
What we ship in this practice.

Why teams hire us.
Fixed Price, Not Hourly
We price the entire modernization project during the Roadmap phase (week 2). You pay exactly what was quoted — no surprises. The average project is $120K with a $80K-$250K range depending on scope.
Senior Engineers Only
IRPR's team averages 10+ years of experience with React, Next.js, cloud infrastructure, and compliance. Every engineer has shipped at least 3 major modernization projects before joining us.
Zero Downtime Migration
We use feature flags (LaunchDarkly) and parallel deployments. Your old site stays live until the new one passes all performance and correctness tests. No traffic loss, no SEO drop.
SEO Preservation Guarantee
We map every legacy URL to its modern equivalent and implement 301 redirects + canonical tags. Post-migration, organic traffic stays within 5% of pre-migration levels. We've done this for 200+ sites.
Compliance Built In
Every modernization includes an automated compliance scan (HIPAA, PCI-DSS, SOC 2) before cutover. We ship with encryption at rest, TLS 1.3, and audit logs — no bolt-on security.
12-Week Delivery, On Average
From kickoff to production release, our average timeline is 10-12 weeks for a full website modernization. 98% of projects ship on the original timeline with zero scope creep.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
