Expert Backend App Development TeamApp Development
We build the backend your product needs. Senior engineers, fixed price, 8-12 week ship.
IRPR builds backend systems that power web apps, mobile apps, and APIs. We use Node.js, Python, Go, and Rust for server-side logic, PostgreSQL and MongoDB for data, and Docker with Kubernetes for deployment.
Every project ships a production-ready backend in 8-12 weeks. Pricing is fixed at $80K-$250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
CTOs hire us when their in-house team lacks senior backend depth. Startup founders hire us to build their MVP backend from scratch. Product managers hire us to add critical features like payment processing, real-time sync, or third-party integrations.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with Express or Fastify. Rate limiting, versioning, and Swagger docs included.
GraphQL Backend
GraphQL servers with Apollo or Hasura. Real-time subscriptions and efficient data fetching for frontend teams.

Why hire an expert backend app development team at IRPR
Your backend is the foundation of every feature your users touch.
A slow or unreliable backend kills user trust before your product has a chance. IRPR's engineers have built 200+ production backends for healthcare, fintech, and ecommerce. We write code that handles 10,000+ requests per second without breaking.
We use automated testing with Jest and Mocha, CI/CD pipelines on GitHub Actions, and infrastructure as code with Terraform. Every backend ships with monitoring dashboards on Grafana and alerts via PagerDuty.
What generic dev shops do vs what IRPR does
Not all backend teams deliver the same result. Compare the difference.
Generic shops often assign junior developers, skip documentation, and hand you code you cannot deploy. IRPR assigns senior engineers only, writes complete API documentation in Swagger, and deploys your backend to a production environment.
Every project at IRPR includes a fixed quote after the Roadmap phase. No hourly billing, no scope creep, no surprise invoices at the end.
- Junior engineers with 1-2 years of experience
- No automated tests or CI/CD
- No Swagger or API documentation
- No monitoring or alerting setup
- Hourly billing with unlimited scope
- Code ownership unclear
- Senior engineers with 8+ years experience on average
- Automated tests with Jest, CI/CD on GitHub Actions
- Swagger docs for every endpoint
- Grafana dashboards + PagerDuty alerts
- Fixed price quoted after a 2-week Roadmap phase
- You own 100% of the code
How IRPR builds your expert backend in 4 phases
We follow a repeatable process that every client sees.
Each phase has a clear deliverable. You review, we adjust, you approve. No guesswork, no long meetings, no hidden delays.
The process starts with a 2-week Roadmap phase where we define the architecture, database schema, and API contract. After that, the fixed price is locked in.
What ships with every backend project
You get a production-ready backend, not a prototype.
Every deliverable is listed in the Roadmap document. Nothing is hidden. You track progress in a shared Linear board.
We use Git for version control. You get access to the repository from day one of development.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions with automated tests
- Swagger/OpenAPI documentation for every endpoint
- Database schema and migration scripts (PostgreSQL or MongoDB)
- Docker containers and docker-compose for local development
- Staging environment on AWS or GCP
- Monitoring dashboards on Grafana
- Error tracking with Sentry
- Deployment runbook with environment variables and secrets
- One month of post-launch support included
What we ship in this practice.
Subscription billing API for a SaaS platform
Built a Stripe-integrated billing backend with webhook handling, usage metering, and proration. Reduced failed payment recovery time by 40%. Tech stack: Node.js, PostgreSQL, Stripe, Bull queue.

Payment processing backend for a fintech app
Built a PCI-DSS Level 1 compliant payment rail integrating Stripe Connect and Plaid. Handles $2M in monthly transaction volume. Tech stack: Node.js, Express, PostgreSQL, Stripe, Plaid.
Real-time collaboration backend for an edtech platform
Developed a WebRTC signaling server with document sync using CRDT-based algorithms. Supports 500+ concurrent users per session. Tech stack: Node.js, Socket.IO, MongoDB, Redis.
Inventory and order management backend for a logistics company
Built a microservices backend for warehouse management, route optimization, and carrier label generation. Reduced order processing time from 4 hours to 20 minutes. Tech stack: Go, gRPC, RabbitMQ, MySQL.
Why teams hire us.
Senior engineers only
Every engineer at IRPR has 8+ years of production backend experience. No juniors, no outsourced teams. You work directly with the engineer writing your code.
Fixed price, not hourly
We quote a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Own your code from day one
You get full ownership of all source code, documentation, and deployment pipelines. No licensing fees. No vendor lock-in. You can take the code and run it yourself.
Production-ready on day one
Every backend ships with monitoring, error tracking, CI/CD, and a runbook. It is not a prototype. It is a system that runs in production on your infrastructure.
Compliance built in
We design backends to meet HIPAA, PCI-DSS, SOC 2, and GDPR requirements from the start. We have passed audits for 15+ healthcare and fintech clients.
Fast kickoff
You can start the Roadmap phase within 2 weeks of signing. No long sales cycles. No discovery sessions that go nowhere. We scope and build fast.
