Experienced Backend App Development ServicesBackend App
We build production-grade backend systems. 200+ products shipped in 12 weeks or less.
IRPR provides experienced backend app development services for companies that need reliable, scalable server-side systems. We use Node.js, Python, Go, Ruby on Rails, and Java with PostgreSQL, MongoDB, Redis, and Kafka to build APIs, microservices, and data pipelines.
Every project ships in 8 to 12 weeks with a fixed price from $80,000 to $250,000. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Our engineers have built backend systems for 200+ products across 50 countries.
Founders hire us when they need a CTO-level backend architect without hiring full-time. CTOs hire us to unblock product roadmaps. Enterprise teams hire us to modernize legacy backends. All get senior engineers who write production code from day one.
Types of software we ship.
RESTful API development
Build stateless, versioned REST APIs with Express.js, FastAPI, or Spring Boot. Includes OpenAPI specs and Postman collections.
Microservices architecture
Decompose monoliths into containerized services using Docker, Kubernetes, and gRPC. Each service scales independently.
Real-time backend systems
Build WebSocket and Server-Sent Events backends with Socket.io, Redis Pub/Sub, or Kafka. Latency under 50ms.
GraphQL API development
Design type-safe GraphQL schemas with Apollo Server or Hasura. Frontend teams query exactly what they need.
Event-driven data pipelines
Build streaming pipelines with Apache Kafka, AWS Kinesis, or RabbitMQ. Process millions of events per day.
Backend for mobile apps
Design push notifications, offline sync, and auth flows for iOS and Android. Uses Firebase Cloud Messaging and AWS AppSync.
Serverless backend systems
Deploy functions on AWS Lambda, Google Cloud Functions, or Azure Functions. Pay only for compute time used.
Third-party integration backends
Connect to Stripe, Salesforce, HubSpot, Twilio, and 100+ APIs. Handle rate limits, retries, and webhooks.
We build for every business type.

Why experienced backend app development matters
A weak backend costs you users and revenue.
Backend systems handle every critical operation: user authentication, data storage, payment processing, and third-party integrations. A poorly designed backend causes slow load times, data loss, and security breaches. IRPR has built backends for 200+ products across healthcare, fintech, and ecommerce.
Our engineers use Node.js, Python, Go, and Java with PostgreSQL, Redis, and Kafka. We design for horizontal scaling from day one. Every system includes automated load testing and error monitoring with Sentry and Datadog.
Generic dev shops vs. IRPR
Not all backend developers deliver the same quality.
Many dev shops assign junior engineers to backend projects. They skip load testing, ignore security best practices, and deliver code that breaks in production. Clients end up with technical debt and missed deadlines.
IRPR assigns senior engineers only. Every engineer has 8+ years of experience building production backends. We write automated tests, set up CI/CD pipelines, and document every API endpoint. Our projects ship on time and on budget.
- Junior engineers on your project
- No load testing before launch
- No monitoring or error tracking
- Hourly billing with no cap
- No security audit
- Code dump with no documentation
- Senior engineers with 8+ years experience
- Load testing with k6 and Artillery
- Sentry and Datadog monitoring from day one
- Fixed price, no surprises
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Full API docs with OpenAPI and Postman
Our backend development process
We build your backend in 4 phases over 12 weeks.
IRPR follows a structured process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price. You know exactly what you get and when you get it.
We start with a 2-day discovery workshop to define requirements. Then we write a detailed Roadmap document with architecture diagrams, API specs, and a timeline. After your approval, we build and test in 2-week sprints. The final release includes deployment and monitoring.
What ships with your backend
Every backend project includes these deliverables by default.
You get more than just code. IRPR ships a complete production-ready system with documentation, monitoring, and deployment scripts. No hidden tasks.
All source code is in your GitHub repository from day one. You own everything. We provide a runbook so your team can operate the system without us.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite with 80%+ coverage
- API documentation with OpenAPI 3.0
- Postman collection for all endpoints
- Docker Compose for local development
- Deployment scripts for AWS, GCP, or Azure
- Sentry error tracking configured
- Datadog monitoring dashboard
- Runbook with operational procedures
What we ship in this practice.
Subscription billing backend for a SaaS startup
Built a multi-tenant billing system with Stripe, PostgreSQL, and Node.js. Handles prorations, upgrades, downgrades, and invoice generation. Reduced billing errors by 90%.
Real-time tracking backend for a logistics company
Built a WebSocket-based tracking system with Socket.io and Redis. Processes 10,000 location updates per second. Reduced delivery disputes by 60%.
HIPAA-compliant patient API for a telehealth platform
Designed a FHIR-compliant API with Python FastAPI and PostgreSQL. Encrypts all PHI at rest and in transit. Passed HIPAA audit on first attempt.
Payment processing backend for a fintech app
Built a PCI-DSS Level 1 compliant payment gateway with Java Spring Boot and AWS. Processes 5,000 transactions per minute. Zero security incidents in 2 years.
Ecommerce product catalog API for a retail brand
Built a GraphQL API with Apollo Server and Elasticsearch. Handles 1 million product SKUs with sub-100ms query times. Increased search conversion by 35%.
Event-driven analytics pipeline for a media platform
Built a Kafka-based pipeline with Go and Apache Flink. Processes 50 million events per day for real-time dashboards. Reduced data latency from 24 hours to 5 minutes.
Why teams hire us.
Senior engineers only
Every engineer on your project has 8+ years of backend experience. No juniors. No offshore teams. You talk directly to the person writing your code.
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. The price you see is the price you pay.
12-week delivery guarantee
We ship production-ready backends in 8 to 12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects ship on time.
Compliance built in from day one
We design for HIPAA, PCI-DSS, SOC 2, and FERPA from the first line of code. No retrofitting. No last-minute audits. Your backend is compliant by default.
Full code ownership
You own every line of code. No licenses, no lock-in, no recurring fees. Source code is in your GitHub repo from sprint one. You can take it anywhere.
Post-launch support included
Every project includes 30 days of post-launch support. We monitor production, fix bugs, and handle incidents. Your team gets full operational handover.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
