Why choose IRPR for legacy modernization?
We have shipped over 200 products across 50 countries with a 98% on-time rate.
Every modernization project starts with a 2-week Roadmap phase where we audit your code, define the target architecture, and give you a fixed price. No surprises.
Our senior engineers average 10+ years of experience. We don't offshore work or use junior developers.
The difference between IRPR and generic dev shops
Most agencies charge hourly and miss deadlines. We don't.
Generic shops often hand off your project to juniors, use hourly billing, and leave you with no documentation. IRPR does the opposite.
We assign senior engineers only, give you a fixed price upfront, and deliver full documentation with every project.
- Hourly billing with no cap
- Unclear timelines
- No compliance focus
- Code ownership disputed
- High developer turnover
- Poor or missing documentation
- Fixed price from the Roadmap phase
- 8-12 week delivery guarantee
- HIPAA/PCI/SOC2 built-in
- Full code ownership in your repo
- Senior engineers only, no turnover
- Comprehensive documentation included
Our legacy modernization process
We follow a proven 4-phase approach that de-risks your project.
Phase 1 audits your existing code and creates a detailed migration plan. Phase 2 designs the new architecture with your team's input.
Phase 3 builds and migrates incrementally, testing each module. Phase 4 deploys to production and hands over everything.
What you get when you modernize with IRPR

What we ship in this practice.
Legacy PHP CRM to React SPA
We migrated a 15-year-old PHP CRM to a React SPA with Next.js and PostgreSQL. Page load time dropped by 60%, and the sales team saved 8 hours per week on data entry. Stack: Next.js, TypeScript, Auth0, PostgreSQL.
Monolith to Microservices for E-commerce
A Magento-based retailer needed 99.9% uptime during Black Friday. We decomposed the monolith into Node.js microservices on AWS Lambda with Stripe. Uptime hit 99.99% and infrastructure costs dropped 30%. Stack: Node.js, AWS Lambda, Stripe, DynamoDB.
Healthcare Portal Modernization
A hospital network's patient portal was on legacy ASP.NET with frequent outages. We rebuilt it with React and FHIR APIs, achieving HIPAA compliance and reducing patient onboarding time by 40%. Stack: React, FHIR, Azure SQL, Okta.
Fintech Dashboard Rewrite
A fintech company's reporting dashboard took 5 minutes to load. We rewrote it with Vue.js and Python FastAPI, cutting report generation to 10 seconds. Stack: Vue.js, FastAPI, Redis, PostgreSQL.
Legacy .NET App to Cloud-Native
A SaaS provider wanted to move from on-prem .NET to Azure. We migrated to .NET Core with Cosmos DB, reducing infrastructure costs by 30% and enabling auto-scaling. Stack: .NET Core, Azure, Cosmos DB, Docker.
Real Estate MLS Integration Upgrade
A real estate platform had a slow MLS data sync that caused stale listings. We built a real-time sync using Next.js, GraphQL, and MongoDB. Listings update within 2 seconds, and agent satisfaction improved by 50%. Stack: Next.js, GraphQL, MongoDB, AWS AppSync.
