Legacy website modernization stats that matter
IRPR ships real results for every legacy project. Here is what we deliver.
We have shipped 200+ legacy modernizations across 50+ countries. Average project takes 8-12 weeks from kickoff to launch.
Our on-time delivery rate is 98%. Every project includes a fixed price quote in the Roadmap phase (week 2). No hourly billing.
The difference between a generic dev shop and IRPR
Most agencies bill hourly and miss deadlines. IRPR does not.
Generic shops start with a discovery phase that takes 4-6 weeks and costs $30K. They never give a fixed price.
IRPR gives you a fixed quote in week 2. We build in 8-12 weeks. You own the code. No scope creep.
- Hourly billing with no cap
- 4-6 week discovery phase
- Junior or offshore engineers
- No compliance knowledge
- No CI/CD on day one
- Code stays on their servers
- Fixed price from week 2
- 12 week max delivery
- Senior engineers only (10+ yrs)
- HIPAA, PCI-DSS, SOC 2 built in
- CI/CD pipeline on GitHub Actions
- Full code ownership in your repo
How legacy website modernization works at IRPR
We follow a 4-phase process to get your old site to a modern stack.
Phase 1 is the Idea call where we map your legacy codebase. Phase 2 is the Roadmap where you get a fixed price.
Phase 3 is the Product build with senior engineers. Phase 4 is the Release with CI/CD and monitoring.
What ships with every legacy modernization project
Every IRPR project includes these deliverables by default. No add-ons.
We ship source code to your repo, a CI/CD pipeline on GitHub Actions, and Sentry error tracking. You own everything from day one.

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. The price you see is the price you pay.
Senior engineers only
IRPR only uses engineers with 10+ years of experience. No juniors, no offshore teams. Every developer has shipped at least 10 products.
12 week delivery, not 12 months
Your legacy site ships in 8-12 weeks. We do not do 2-year roadmaps. Every project has a hard deadline with a fixed scope.
You own the code
Source code goes into your GitHub repo on day one. Full ownership. No lock-in. No hidden licenses. You can take it anywhere.
Compliance built in
HIPAA, PCI-DSS, SOC 2, and FERPA are part of every project. We do not add compliance later. It ships with the first commit.
CI/CD from day one
Every project ships with a CI/CD pipeline on GitHub Actions. Automated tests, linting, and deployments. No manual steps.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
