Best Web Application Modernization ServicesModernization Services
IRPR rebuilds legacy web apps into fast, secure, cloud-native systems. You get a fixed price, a 12-week timeline, and full code ownership.
IRPR provides the best web application modernization services for companies running legacy code on old frameworks like jQuery, Ruby on Rails, or PHP. We rebuild your app using Next.js, Node.js, PostgreSQL, and deploy it on AWS with auto-scaling and CI/CD pipelines.
Every modernization project ships in 8-12 weeks with a fixed price of $80K to $250K. We handle compliance too — HIPAA for healthcare apps, PCI-DSS for fintech, and SOC 2 for SaaS platforms. You keep the source code and all infrastructure.
We work with CTOs who need to kill technical debt, product managers who want faster feature releases, and engineering leads who are tired of patching a 10-year-old codebase. No hourly billing. No surprise fees. Just a modern app that works.
Types of software we ship.

How we modernize your web application
We follow a proven 4-step process that ships your modernized app in 8-12 weeks.
Step 1: We audit your existing codebase, database schema, and infrastructure. We identify every dependency, API endpoint, and security gap. This takes 1 week.
Step 2: We build a new architecture using Next.js on the frontend and Node.js on the backend, deployed to AWS with CI/CD pipelines. You see a working prototype by week 4.
Step 3: We migrate your data, users, and traffic in a single weekend with zero downtime. We use database replication and DNS switching to keep your app live.
Step 4: We hand over the full source code, infrastructure-as-code files, and a runbook. You own everything. No ongoing licenses. No vendor lock-in.
Generic dev shop vs IRPR
Most agencies treat modernization as a never-ending project. IRPR ships a finished app in 12 weeks.
A generic dev shop starts with an open-ended estimate and charges by the hour. They often use the same old framework because they don't want to learn new tools. They rarely handle compliance.
IRPR gives you a fixed price from day one. We rewrite your app in modern tech like Next.js and AWS. Every project ships with a security audit, a migration plan, and a handover document.

- No post-launch support
- Fixed price in the Roadmap phase
- Rebuilds in Next.js and AWS
- HIPAA, PCI-DSS, SOC 2 ready
- Full source code in your repo
- 12-week delivery with a deadline
- 30-day post-launch support included
The modernization process in 4 phases
Every project follows the same sequence: Idea, Roadmap, Product, Release.
Phase 1: Idea. We review your current app, your business goals, and your compliance needs. We create a 1-page spec with every feature and integration.
Phase 2: Roadmap. We write a detailed plan with a fixed price and a 12-week timeline. You approve the plan before any code is written.
Phase 3: Product. We build the new app in weekly sprints. You see a working demo every Friday. We run automated tests, load tests, and security scans.
Phase 4: Release. We deploy the new app to production with a DNS switch. We run a 30-day monitoring period to catch any issues.
What ships with every modernization
Every project includes a full set of deliverables so you can run the app yourself.
You get the source code in your private GitHub repo, the CI/CD pipeline configured on GitHub Actions, and the infrastructure-as-code in Terraform. We also include a 30-day monitoring period with Sentry error tracking.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure-as-code in Terraform
- Database migration scripts
- Load testing reports with k6
- Security audit report with OWASP tools
- Sentry error tracking setup
- Automated backup configuration
- DNS migration plan
- 30-day post-launch monitoring
What we ship in this practice.
Legacy healthcare portal rewrite
A hospital network with a 15-year-old PHP portal needed HIPAA compliance. IRPR rebuilt it in Next.js with OAuth 2.0 and encrypted data storage. The new app reduced page load time by 4 seconds and passed a HIPAA audit in week 6.
Fintech payment platform migration
A payment processor running on old Ruby on Rails wanted PCI-DSS compliance. IRPR migrated to Node.js and PostgreSQL on AWS. The new system handled 10,000 transactions per second with zero downtime during the switch.
SaaS CRM re-architecture
A SaaS company with a monolith codebase wanted to ship features faster. IRPR broke it into 12 microservices with Kubernetes. The team went from 1 release per month to 1 release per week.
Ecommerce platform frontend upgrade
An ecommerce brand with a slow jQuery frontend wanted a modern storefront. IRPR rebuilt it in React with server-side rendering. Conversion rate increased by 15% and page load time dropped from 6 seconds to 1.5 seconds.
Real estate MLS portal modernization
A real estate platform with a legacy database needed faster search. IRPR migrated from SQL Server to PostgreSQL with full-text search. Agents now get property results in under 200 milliseconds instead of 4 seconds.
EdTech platform cloud migration
A school management system running on a shared server wanted cloud hosting. IRPR moved it to AWS with auto-scaling and load balancing. The platform now handles 50,000 concurrent users during peak hours without any slowdown.
Why teams hire us.

12-week delivery, not 12 months
We ship every modernization in 8-12 weeks. We use weekly sprints, automated testing, and a dedicated QA team. 98% of our projects deliver on time.
Full code ownership
You get the source code in your GitHub repo, the infrastructure files in Terraform, and the database scripts. No proprietary frameworks. No vendor lock-in. You can fire us and keep running.
