Leading Backend App Development AgencyBackend App
We build backend systems that handle millions of requests. You get a production-ready API in 12 weeks.
IRPR builds backend applications for high-load platforms. We use Node.js, Python, Go, and AWS Lambda to create scalable APIs. Our team designs databases with PostgreSQL and Redis for fast data access.
Every project ships a fully functional backend in 12-14 weeks. Fixed pricing starts at $80K and goes to $250K for complex systems. We build to SOC 2 and HIPAA compliance when needed.
We work with CTOs scaling their product, founders launching a SaaS MVP, and enterprise teams migrating to microservices. Also with product managers who need a reliable API layer.
Types of software we ship.
REST API development
Build RESTful APIs with OpenAPI specs and Swagger documentation. Supports JSON and XML responses. Integrates with any frontend.

Why choose a leading backend app development agency
We ship production backends that meet compliance and performance standards.
Our team has delivered 200+ backend systems across 50 countries. Each project includes load testing and security audits.
We guarantee 99.9% uptime for production APIs. Our average MVP delivery time is 12 weeks from roadmap start.
Backend development done right
Not all agencies deliver reliable, scalable backends. Here's how we differ.
Many shops write code that breaks under load. They use outdated stacks and leave documentation missing.
IRPR writes modular, tested code from day one. We enforce code reviews, automated tests, and API documentation.
- No architecture review
- No load testing
- Hourly billing
- No documentation
- No CI/CD pipeline
- No post-launch support
- Architecture review in week 1
- Load testing with k6
- Fixed price per phase
- OpenAPI documentation auto-generated
- CI/CD with GitHub Actions
- 12-month warranty
Our backend development process
We follow a four-phase approach to deliver your backend system.
Each phase has clear deliverables and a fixed price. You review progress at each milestone.
The process starts with an idea alignment call and ends with a deployed, tested API.
What ships with every backend project
You get more than just code. Our delivery includes everything needed to run in production.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Sentry error tracking integration
- Datadog monitoring dashboard
- Postman API collection
- Architecture documentation (draw.io)
- Load test results (k6 report)
- Security audit report (OWASP)
- Docker containers for each service
- Infrastructure as code (Terraform)
What we ship in this practice.
