Professional Backend App Development CompanyBackend App
We build backend systems that scale to millions of users. Fixed pricing, 8-12 week delivery, and full code ownership.
IRPR builds production-grade backend applications for SaaS, fintech, healthcare, and ecommerce companies. We use Node.js, Go, Python, PostgreSQL, Redis, Kafka, and Kubernetes to create scalable, secure APIs and microservices.
Every project ships with source code in your GitHub repo, CI/CD pipelines (GitHub Actions), Docker containers, and Sentry error monitoring. Timelines range from 8 to 12 weeks, with fixed pricing between $80K and $250K. We build to HIPAA, PCI-DSS, and SOC 2 standards from day one.
Our clients include SaaS founders needing a scalable API backend, CTOs at fintech startups requiring PCI-DSS compliant payment processing, healthcare IT directors needing HIPAA-compliant data pipelines, and ecommerce VPs of engineering requiring high-availability order backends.

Why choose a professional backend app development company
Our track record speaks for itself.
IRPR has shipped over 200 backend applications across 50 countries. We specialize in systems that need high concurrency, low latency, and strict compliance.
Every backend we build includes automated testing, CI/CD, and monitoring. We guarantee 99.9% uptime and 98% on-time delivery. Our fixed pricing model means no surprises.
The difference between hiring IRPR and a generic dev shop
Most backend projects fail due to poor architecture and unclear pricing.
Generic dev shops often lack compliance expertise and deliver code without documentation or CI/CD. You end up with technical debt and surprise bills.
IRPR builds compliance-first, documentation-everywhere, and ships your code with fully automated pipelines. You get fixed pricing and a dedicated PM.
- No clear timeline
- Hourly billing
- No compliance expertise
- Code not documented
- No CI/CD setup
- No post-launch support
- Fixed price from week 2
- 8-12 week delivery
- HIPAA/PCI/SOC 2 compliance built-in
- Full code ownership with CI/CD
- Sentry error tracking included
- Dedicated PM with weekly updates
Our backend development process
We follow a clear 4-phase framework.
Idea: We map your requirements into a technical specification. Within 1-2 weeks we have a clear architecture and technology stack.
Roadmap: In week 2 we produce a fixed price quote and detailed timeline. From there we build iteratively in two-week sprints.
What ships with your backend
Every project includes these deliverables by default.
Source code, documentation, and monitoring tools are included in the fixed price.
- Source code in your repo
- CI/CD pipeline (GitHub Actions)
- Docker containerization
- API documentation (Swagger)
- Sentry error tracking
- Cloud deployment scripts
- Load testing results
- Post-launch 30-day support

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.
Full IP ownership from day one
You own 100% of the source code, documentation, and IP. IRPR never claims ownership. The code is delivered in your GitHub repository.
Compliance-first architecture
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from the start. Over 50 projects have passed compliance audits without rework.
Senior engineers only
Every project is staffed with senior engineers averaging 10+ years of experience. No junior developers, no outsourcing to low-cost markets.
8-12 week delivery guarantee
We commit to a fixed timeline and deliver on time 98% of the time. If we miss the deadline, you don't pay for the overage.
Post-launch support included
Every project includes 30 days of post-launch monitoring and bug fixes. We also set up Sentry and PagerDuty alerts so you stay informed.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
