Leading Custom Backend Development VendorBackend Development
We build backend systems that handle millions of requests. Fixed price, 8-12 week MVPs, senior engineers only.
IRPR is a leading custom backend development vendor. We build server-side systems using Node.js, Python, Go, and Rust. Our engineers design RESTful APIs, GraphQL endpoints, event-driven architectures, and microservices that scale to 100k+ concurrent users.
Every project ships within 8-12 weeks for the MVP. Pricing starts at $80K and goes to $250K for complex systems with multiple integrations. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Our team has built backend systems for fintech platforms processing $50M+ monthly and healthcare apps managing 1M+ patient records.
We work with CTOs who need a reliable backend for a new SaaS product. We work with founders who need a scalable API for their mobile app. We work with product managers who need to replace a legacy monolith with microservices. We also work with enterprise architects who need a secure backend for a regulated industry.

Why choose a leading custom backend development vendor
IRPR has shipped 200+ backend systems for clients in 50+ countries.
We are a leading custom backend development vendor because we only hire senior engineers with 8+ years of experience. Every project gets a dedicated team of 3-5 engineers who have built systems handling 1M+ daily requests. We do not outsource to junior developers or use offshore body shops.
Our process starts with a 2-week Roadmap phase where we define the architecture, database schema, and API contracts. You get a fixed price and a clear timeline before any code is written. We have a 98% on-time delivery rate for all projects.
How IRPR differs from other backend vendors
Most dev shops bill hourly and over-engineer. IRPR does the opposite.
We have seen clients come to us after spending $150K with generic dev shops that delivered spaghetti code. Those projects had no tests, no CI/CD, and no documentation. The code was unmaintainable and the vendors kept charging for bug fixes.
IRPR delivers production-ready backend systems with full test coverage, automated deployments, and comprehensive API docs. Every project includes a 30-day warranty period where we fix any issues at no cost.
- Hourly billing with no cap
- Junior developers on the team
- No automated tests
- No CI/CD pipeline
- Code delivered without docs
- No SLA for uptime
- Fixed price after Roadmap phase
- Senior engineers only (8+ years)
- 90%+ test coverage required
- CI/CD with GitHub Actions and Docker
- OpenAPI docs auto-generated
- 99.9% uptime SLA
Our backend development process
From idea to production in 8-12 weeks with clear milestones.
Every project follows our four-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we define the architecture, data model, and API contracts. You approve the plan and get a fixed price before we write a single line of code.
The Product phase takes 6-8 weeks. Our engineers build the backend in two-week sprints with daily standups and weekly demos. You see working software every week. The Release phase includes load testing, security audit, and deployment to production.
What ships with your backend
You own everything. Source code, infrastructure, and documentation.
When IRPR builds your backend, you receive full ownership of all source code, database schemas, and infrastructure configurations. There is no lock-in, no recurring license fees, no hidden costs. You can take the code to any other team after the project ends.
Every delivery includes a CI/CD pipeline on GitHub Actions, Docker containers for each service, and monitoring with Datadog or Sentry. Your team can deploy to production with a single pull request merge.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker Compose for local development
- Kubernetes manifests for production
- OpenAPI 3.0 documentation
- Database migration scripts
- Sentry error tracking
- Datadog monitoring dashboard
- Load test results (k6 or Artillery)
- Security audit report (OWASP top 10)
