Why choose an experienced backend app development firm
Backend is the foundation of every app. A bad backend means slow load times, security holes, and scaling nightmares.
IRPR has shipped 200+ backend systems across 50 countries. Our senior engineers average 10+ years of experience. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS. Every project includes automated testing, CI/CD, and monitoring from day one.
We work with startups that need a backend MVP in 8-12 weeks. We work with enterprises that need to migrate from monoliths to microservices. We work with fintech companies that need PCI-DSS compliant payment backends. Every project has a fixed price and a clear timeline.
How IRPR differs from generic development shops
Most agencies promise full-stack but deliver half-baked backends. IRPR is different.
Generic dev shops assign junior developers to backend work. They use boilerplate code and skip testing. They bill by the hour and scope creeps. They deliver late and leave you with unmaintainable code.
IRPR assigns senior engineers only. We write custom backend code with 90%+ test coverage. We give you a fixed price in week 2. We ship on time and hand over full ownership of the code.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No automated testing
- No CI/CD pipeline
- No monitoring or alerting
- Code ownership unclear
- Senior engineers with 10+ years experience
- Fixed price from Roadmap phase
- 90%+ test coverage
- CI/CD on GitHub Actions
- Sentry error tracking and Datadog monitoring
- Full code ownership transferred
Our backend development process
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1 (Idea): We map your requirements, user flows, and data model. This takes 1 week. You get a written specification.
Phase 2 (Roadmap): We design the architecture, choose the tech stack, and give you a fixed price. This takes 1 week. You get a detailed project plan.
Phase 3 (Product): We build the backend in 6-10 weeks. We deploy to staging and run automated tests. You get weekly demos.
Phase 4 (Release): We deploy to production, set up monitoring, and hand over the code. You get a 30-day warranty.
What ships with every backend project
Every backend project includes these deliverables by default. No hidden costs.
We ship source code in your private GitHub repo. We set up CI/CD with GitHub Actions. We configure Sentry for error tracking and Datadog for performance monitoring. We write API documentation with Swagger or Postman. We deploy to AWS, GCP, or Azure. We give you a 30-day warranty for bug fixes.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
We hire only senior engineers with 10+ years of experience. No junior developers. Every engineer has shipped production backends at scale. You get a lead engineer who owns the project end to end.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our process is optimized for speed without cutting corners. You get a working backend with tests, docs, and monitoring.
Full code ownership
You own all source code, documentation, and infrastructure. No proprietary frameworks, no lock-in. You can take the code to any team after the project ends.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends. We handle encryption, access controls, audit logs, and data retention. You don't need to retrofit compliance later.
Production monitoring included
Every backend ships with Sentry error tracking and Datadog performance monitoring. We set up alerts for downtime, slow queries, and error spikes. You know when something breaks before your users do.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
