Experienced Backend App Development CompanyBackend App
We build backend systems that scale. 200+ products shipped to 50+ countries with 98% on-time delivery.
IRPR is an experienced backend app development company that builds high-performance server-side systems using Node.js, Python, Go, and Rust. We design databases with PostgreSQL, manage containers on Kubernetes, and deploy on AWS with CI/CD pipelines.
Most projects ship in 12-14 weeks at a fixed price between $80K and $250K. Every backend complies with SOC 2, HIPAA, or PCI-DSS depending on your industry. You get full ownership of all source code and infrastructure configs.
Our clients are founders launching SaaS platforms that need multi-tenant backends, CTOs replacing legacy monoliths with microservices, and product managers building REST or GraphQL APIs for mobile apps. We also work with compliance officers in healthcare and fintech.
Types of software we ship.
REST API development
Build stateless RESTful APIs with Node.js or Python. Use JWT auth and Swagger docs. Deploy on AWS Lambda or EC2.
Microservices architecture
Split monoliths into decoupled services with Docker and Kubernetes. Each service handles one domain and scales independently.
GraphQL backend
GraphQL APIs using Apollo Server and Prisma ORM. Clients fetch exactly the data they need. Versionless and fast.
Real-time backend

Why choose an experienced backend app development company
Your backend is the foundation of your product. A poorly built one means downtime, slow features, and angry users.
IRPR has shipped 200+ backends for clients in 50 countries. Our team includes senior engineers who have built systems handling 10,000+ requests per second. We use proven patterns like CQRS, event sourcing, and circuit breakers.
Every project starts with a 2-week Roadmap phase where we audit your existing system (or requirements) and produce a fixed quote. No hourly billing. No surprises. The average timeline to a production-ready backend is 12 weeks.
The difference between IRPR and generic dev shops
Most agencies charge by the hour and deliver late. We do the opposite.
Generic dev shops often assign junior developers to backend work. They use copy-paste code, skip testing, and have no compliance experience. Projects frequently run over budget without clear milestones.
IRPR assigns only senior engineers with 8+ years of experience. Every backend undergoes code review, load testing, and security audits. We ship on time because we define scope in the Roadmap phase before a single line of code is written.
- Assigns junior devs to backend work
- No fixed price, bills hourly
- Skips load testing
- No compliance audits
- Scope creep is common
- Late delivery every project
- Senior engineers only (8+ years)
- Fixed price in Roadmap phase
- Load tests every endpoint
- HIPAA, PCI, SOC 2 compliant
- Scope locked in week 2
- 98% on-time delivery
Our backend development process
Four phases get you from idea to production in 12-14 weeks.
The process starts with a 2-week discovery phase called the Roadmap. In it, we define the data model, API contract, hosting strategy, and security requirements. Everything is written down before code begins.
We then build in 2-week sprints with daily standups and weekly demos. After production release, we provide 30 days of warranty and transfer all code and documentation to your repo.
Everything that ships by default
When you hire IRPR as your experienced backend app development company, here is what you get.
Every backend project includes production-ready code, automated tests, and infrastructure as code. We do not hand over half-finished repos. You get a fully deployable system with monitoring and rollback capabilities.
All projects include documentation in Markdown format, Postman collections, and a runbook for your infrastructure. The code is yours from day one.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Infrastructure as code (Terraform or Pulumi)
- API documentation (OpenAPI or GraphQL schema)
- Unit and integration tests (90%+ coverage)
- Load test results and performance report
- Monitoring and alerting (Datadog or Sentry)
- Database migration scripts and seed data
- Deployment runbook and rollback procedure
What we ship in this practice.
