Why you need a dedicated backend app development partner
Your backend is the foundation of your product. A bad backend breaks everything.
IRPR has shipped 200+ backend systems across 50 countries. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS. Every project includes CI/CD, monitoring, and error tracking from day one.
We work as your backend app development partner, not a vendor. You get a fixed price, a clear roadmap, and senior engineers who write code you own. No hourly billing. No scope creep.
Generic dev shop vs IRPR as your backend partner
Not all backend development partners are the same. Here is the difference.
Generic dev shops bill hourly, change scope mid-project, and hand you code with no tests. IRPR gives you a fixed price, a clear roadmap, and production-ready code.
We have built backends for HIPAA-compliant healthcare apps, PCI-DSS payment systems, and SOC 2 SaaS platforms. Every project ships with automated tests, CI/CD, and monitoring.
- Hourly billing with no cap
- Scope creep on every change
- Junior developers on your project
- No compliance knowledge
- Code with no tests or docs
- No post-launch support
- Fixed price from the start
- Clear roadmap with milestones
- Senior engineers only (8+ years)
- HIPAA, PCI-DSS, SOC 2 ready
- Automated tests and CI/CD included
- Post-launch monitoring and support
How we build your backend in 4 phases
Our process is designed for speed and clarity. No surprises.
We start with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed price and a timeline before we write a single line of code.
Then we build, test, and deploy in 6-10 weeks. Every sprint ends with a working demo. You see progress every week.
What ships with every backend project
Every project includes these deliverables by default. No hidden costs.
You own everything we build. Source code, documentation, infrastructure config, and CI/CD pipelines are all yours. We hand over full access on day one.
We also include monitoring, error tracking, and a 30-day support window. Your backend stays healthy after launch.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated unit and integration tests (80%+ coverage)
- API documentation with OpenAPI or GraphQL schema
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking and Datadog monitoring
- Docker containers for local development
- Database migration scripts and seed data
- Post-launch support for 30 days
- Full ownership of all code and IP

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 build.

Every engineer on your project has 8+ years of experience. No juniors, no offshore teams, no handoffs. You work directly with the people writing your code.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our record is 6 weeks for a payment API. Speed comes from experience, not cutting corners.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends from day one. No retrofitting. Our engineers know the requirements and build to them.
You own the code
Full source code, documentation, and infrastructure config are yours. No licensing fees, no lock-in, no hidden terms. You can take it anywhere.
Post-launch support included
Every project includes 30 days of post-launch support. We monitor, fix bugs, and handle edge cases. Your backend stays healthy after we hand it over.
