Premium Custom Backend Development VendorBackend Development
We build backend systems that handle millions of requests. 200+ products shipped for clients in 50 countries.
IRPR is a premium custom backend development vendor. We build backend systems using Go, Node.js, Python, and Rust on top of PostgreSQL, MongoDB, and Kafka. Every system is designed for scale, security, and uptime.
Our engagement runs 12-14 weeks for a production-ready MVP. Fixed pricing starts at $80K and goes up to $250K. We deliver under HIPAA, PCI-DSS, and SOC 2 compliance when needed.
Three types of buyers hire us: CTOs who need to ship a complex backend fast, startup founders who want a reliable MVP without technical debt, and enterprise architects migrating legacy monoliths to microservices.
Types of software we ship.

Why Choose a Premium Backend Development Vendor
The backend is the foundation of your product. A small mistake can cost months of rework.
IRPR has shipped over 200 backend systems. Our engineers average 10+ years of experience with production systems handling 100K+ requests per second. We use proven patterns: circuit breakers, retry logic, and distributed tracing.
Every backend project starts with a 2-week Roadmap phase. You get detailed specifications, architecture diagrams, and a fixed price before any code is written. No surprises later.
The Difference Between IRPR and a Generic Dev Shop
Most agencies promise premium but deliver generic. IRPR is built differently.
Generic dev shops assign junior developers and bill by the hour. They rewrite the same code multiple times and have no accountability. You pay for their learning curve.
IRPR assigns a senior team that stays on your project from Roadmap to Release. We own the outcome, not just the hours. Our fixed pricing means you know the cost upfront.
- Junior devs learning on your dime
- Hourly billing with no cap
- No compliance knowledge
- One-off integration scripts that break
- No monitoring or alerting setup
- Code dumped via email at handoff
- Senior engineers with 10+ years experience
- Fixed price from week 2
- HIPAA, PCI-DSS, SOC 2 built in
- Automated CI/CD with tests
- Sentry error tracking, Datadog monitoring
- Full source code in your private repo
Our 4-Phase Backend Development Process
We follow a disciplined process so you never waste time or money.
Every project goes through four phases: Idea, Roadmap, Product, Release. This structure ensures alignment, predictability, and quality.
The Roadmap phase is a 2-week sprint where we produce architecture documents, API specs, and a fixed price contract. You approve every decision before we write a line of production code.
What Ships When You Hire IRPR
We deliver a complete backend system, not just code.
When we finish, you get everything needed to run and maintain the backend yourself. No black boxes.
All code, documentation, and infrastructure configuration are in your own repositories. We also leave behind runbooks and dashboards.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- API documentation (OpenAPI/Swagger or Postman collection)
- Database migration scripts and seed data
- Sentry error tracking and Datadog monitoring
- Infrastructure as code (Terraform or Pulumi)
- Load testing report (k6 or Artillery results)
- Post-launch runbook for on-call engineers
- Architecture diagram (C4 model or Draw.io)
