We build backend systems that ship in 12 weeks. Fixed price, senior engineers, full code ownership.
IRPR is an expert backend app development studio. We build custom APIs, microservices, and cloud infrastructure using tools like Node.js, Python/Django, and Go.
Every project ships in 8 to 12 weeks with a fixed price between $80K and $250K. Our backend systems meet compliance standards like HIPAA, PCI-DSS, and SOC 2.
We work with SaaS founders who need a scalable backend, CTOs migrating monoliths to microservices, product owners integrating third-party APIs, and startups launching MVPs that must handle thousands of concurrent users.
Types of software we ship.
REST API development
Custom REST APIs with OpenAPI specs, rate limiting, and caching via Redis. We use Express.js or FastAPI.
GraphQL backend
GraphQL APIs with Apollo Server, resolver optimization, and data federation for complex queries.
Microservices architecture
Decoupled services with Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
Real-time backend
WebSocket or WebRTC backends for live chat, notifications, and collaborative tools using Socket.io.
Data pipeline & ETL
Batch and streaming data pipelines with Apache Airflow, Snowflake, or BigQuery for analytics.

Why you need an expert backend app development studio
Your backend is the foundation of every feature your users see and every transaction you process.
A poorly architected backend causes slow load times, broken integrations, and security breaches. IRPR builds backends that handle 10,000 requests per second with 99.9% uptime. Our team uses Node.js, Django, and Go to deliver production-ready APIs in 12 weeks.
We have shipped over 200 products for clients in 50 countries. Every backend includes CI/CD pipelines, automated testing, and a monitoring stack with Sentry and Datadog. You get full source code and AWS/GCP infrastructure managed from day one.
The difference between a freelancer and an expert backend studio
Hiring a solo developer often leads to code that breaks, undocumented APIs, and missed deadlines.
A freelancer may build a working backend, but they rarely design for scale, security, or team handoff. IRPR delivers a production-grade system with load testing, error tracking, and infrastructure-as-code. Our engineers have built backends for companies processing $50M in monthly transactions.
We assign a senior engineer and a project manager to every engagement. Code is reviewed, tested, and documented before delivery. You get a system that your internal team can maintain without the original developer.
- No code reviews or testing
- Unclear pricing, hourly billing
- No compliance expertise (HIPAA, PCI)
- Single developer point of failure
- No CI/CD or monitoring setup
- Code ownership unclear
- Automated tests & code reviews on every pull request
- Fixed price agreed in week 2
- HIPAA, PCI-DSS, SOC 2 built in
- Senior engineer + PM on every project
- CI/CD pipeline with GitHub Actions, Sentry, Datadog
- Full source code ownership
How we build your backend in 12 weeks
Every project follows a 4-phase process designed for speed, transparency, and quality.
We start with a 2-week Roadmap phase where we define the architecture, API contracts, and infrastructure plan. You pay a fixed price for this phase, and we produce a detailed spec and a fixed quote for the full build.
The Product phase runs 8 to 12 weeks. We build your backend in 2-week sprints with demos every Friday. Changes are fast because we use feature flags and continuous deployment.
What ships with every backend project
You don't just get code. You get a complete operational system ready for production.
Every backend we build includes automated tests, infrastructure scripts, monitoring, and documentation. No hidden work, no gaps for you to fill.
We set up deployment pipelines that run tests and deploy to staging on every merge. Production deployments are one-click rollbacks.
- Source code in your GitHub or GitLab repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated test suite (unit, integration, e2e)
- API documentation (OpenAPI/Swagger)
- Infrastructure-as-code (Terraform or CloudFormation)
- Monitoring with Sentry error tracking and Datadog metrics
- Database schema with migrations and backups
- Load testing report (k6 or Artillery)
- Deployment guide and runbook
- 90-day post-release maintenance
