Backend App Development StudioDevelopment Studio
We build production-grade backends for SaaS, fintech, and healthcare. 200+ products shipped on time, fixed price.
IRPR is a backend app development studio that builds production-grade backends for startups and enterprises. We use Node.js, Python, Go, PostgreSQL, MongoDB, Redis, Kafka, and Docker to ship fast, scalable APIs.
Every project ships in 8 to 12 weeks at a fixed price between $80K and $250K. We build HIPAA, PCI-DSS, and SOC 2 compliant backends from day one. No hourly billing, no scope creep.
Our clients are SaaS founders launching an MVP, fintech CTOs needing PCI-compliant payment APIs, healthcare startups requiring HIPAA-compliant patient data systems, and ecommerce companies building order processing backends at scale.

Why Choose a Backend App Development Studio Like IRPR?
We have shipped over 200 backend apps across fintech, healthcare, SaaS, and ecommerce.
Most dev shops bill by the hour and deliver late. IRPR uses a fixed price model with a 12-week delivery guarantee. Our clients get a production-ready backend with compliance, monitoring, and documentation built in.
Every engineer on our team averages 12+ years of experience. We do not outsource or hire junior developers. This means fewer bugs, faster delivery, and a backend that scales from day one.
Generic Dev Shop vs IRPR for Backend Development
Most dev shops can't deliver a production-ready backend in 12 weeks with compliance baked in.
A generic development agency often starts with junior developers, unclear milestones, and hourly billing. You end up paying more for a slower result with no code ownership guarantee.
IRPR works differently. We lock scope and price after the Roadmap phase, assign senior engineers, and ship every backend with full documentation and post-launch support.
- Hourly billing with no fixed cap
- Unclear compliance handling
- Junior developers learning on your project
- No dedicated project manager
- Code ownership not specified
- No post-launch support
- Fixed price contract with no surprises
- HIPAA, PCI, SOC 2 compliance built in
- Senior engineers only (10+ years exp.)
- Dedicated PM and weekly demos
- You own all code and IP
- 2 months post-launch support included
Our Backend App Development Process
We follow a 4-phase process to deliver your backend in 12 weeks, from idea to deployment.
Phase 1 captures your goals and technical constraints. Phase 2 produces a fixed price quote and timeline. After you approve, senior engineers build in 2-week sprints with weekly demos.
The final phase launches to production with CI/CD, monitoring, and a 2-month support period. You own everything from day one.
What Ships with Your Backend App
Every project includes these deliverables, tested and documented.
We deliver more than just code. Each project comes with automated tests, API docs, CI/CD pipelines, and compliance documentation. You can hand the project to your internal team immediately.
All source code is in your private repository from day one. No proprietary frameworks, no license restrictions.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Automated tests (unit + integration)
- API documentation (Swagger/OpenAPI)
- Database schema migration scripts
- Docker containerized deployment
- SSL and security best practices
- Post-launch support for 2 months
- Compliance documentation (HIPAA/PCI) if required
What we ship in this practice.
