Best Web Application Modernization ConsultantsModernization Consultants
We modernize legacy apps in 12-16 weeks. Fixed price, no surprises.
IRPR is a software development studio that specializes in modernizing legacy web applications. We replace outdated monoliths built on PHP, .NET Framework, or Java with modern stacks like Next.js, Node.js, Python, Go, and React, deployed on AWS or GCP.
Every modernization project ships in 12-16 weeks with a fixed price ranging from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. Our team includes senior engineers only, averaging 12+ years of experience.
Companies hire us when their legacy app slows down business. CIOs need to reduce technical debt. CTOs want to move to microservices. Product owners need faster release cycles. VPs of engineering need a reliable partner with a predictable timeline.
Types of software we ship.
Monolith to microservices
Break a single large codebase into independent services communicating via REST or gRPC. Use Docker and Kubernetes for orchestration.
Cloud migration
Move on-premise apps to AWS, Azure, or GCP. Rehost, replatform, or refactor based on cost and performance needs.
Legacy UI redesign
Replace jQuery or AngularJS frontends with React, Vue, or Next.js. Implement responsive design and modern component libraries.
API modernization
Replace SOAP or XML-RPC APIs with RESTful or GraphQL endpoints. Add OpenAPI documentation and rate limiting.
Database modernization
Migrate from Oracle or SQL Server to PostgreSQL or Aurora. Implement schema changes and zero-downtime migrations.
CI/CD pipeline setup
Build automated build, test, and deploy pipelines using GitHub Actions, GitLab CI, or Jenkins. Enable canary deployments.
Security and compliance upgrade
Add OAuth 2.0, SSO, encryption at rest and in transit. Achieve SOC 2 or PCI-DSS compliance during the migration.
Performance optimization
Profile and optimize slow endpoints, database queries, and frontend rendering. Target sub-200ms response times.
We build for every business type.
Healthcare
Fintech
Ecommerce
SaaS

Why You Need the Best Web Application Modernization Consultants
Legacy apps cost more to maintain than to replace.
A 10-year-old .NET Framework app on Windows Server costs $50K/year in licensing and patching alone. IRPR modernizes it to a containerized Node.js app on Linux, cutting infrastructure costs by 60% and enabling auto-scaling.
Our clients see 3x faster release cycles after modernization. Deployments that took a week now take 10 minutes. We also reduce bug counts by 80% because we replace untested legacy code with a fully tested modern stack.
Generic Dev Shop vs IRPR: Who Should You Trust?
Not all consultants deliver the same result.
Generic dev shops quote hourly rates and timelines that slip. They use junior developers and copy-paste code. IRPR is different: we assign senior engineers only, give a fixed price, and deliver on time.
Our clients choose us because we treat modernization as a product, not a project. We own the outcome, not just the output.
- Hourly billing with no cap
- Junior developers learning on your dime
- Timelines that slip 3-6 months
- No compliance expertise
- Code delivered without tests
- No post-launch support
- Fixed price from the Roadmap phase
- Senior engineers only, 12+ years average
- 12-16 week delivery guarantee
- HIPAA, PCI, SOC 2 built in
- 100% test coverage on new code
- 30-day post-launch warranty
Our Modernization Process: 4 Phases
We follow a proven 4-phase process to modernize your web application.
Phase 1 is the Roadmap. We audit your existing codebase, infrastructure, and dependencies. We give you a fixed quote and a detailed plan by week 2.
Phases 2-4 are build, test, and release. You see working software every 2 weeks. No surprises.
What Ships After Modernization
You own everything. No lock-in, no black boxes.
Every modernization project delivers a complete, production-ready system. You get full ownership of the source code, infrastructure configs, and documentation.
We also set up monitoring, logging, and alerting so your team can operate the new system from day one.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Docker Compose and Kubernetes manifests
- Database migration scripts with rollback
- Sentry error tracking and Datadog monitoring
- OpenAPI documentation for all APIs
- Load testing report with k6
- 30-day post-launch support and bug fixes
- Architecture decision records (ADRs)
- Runbooks for incident response
