Expert Backend App Development ServicesDevelopment Services
We build backend systems that handle millions of requests without breaking. 12 weeks from spec to production, fixed price.
IRPR provides expert backend app development services for companies that need reliable, scalable infrastructure. We build with Node.js, Python, Go, PostgreSQL, Redis, and AWS Lambda to handle high traffic and complex data flows.
A typical backend project ships in 12 weeks for an MVP, with pricing from $80K to $250K depending on scope. Every project includes load testing, CI/CD pipelines, and compliance-ready architecture (HIPAA, PCI-DSS, SOC 2).
We work with CTOs who need to scale their platform without hiring a full in-house team, founders launching a SaaS product who want production-ready APIs from day one, and enterprise directors migrating legacy systems to modern cloud infrastructure.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with Express.js or FastAPI, including rate limiting, authentication, and OpenAPI documentation.
GraphQL Backend
Implement GraphQL servers with Apollo or Hasura for flexible data fetching, real-time subscriptions, and schema stitching.
Microservices Architecture
Design decoupled microservices with message queues (RabbitMQ, Kafka), container orchestration (Kubernetes), and service mesh.
Real-Time Backend
Build WebSocket and Server-Sent Events systems with Socket.io or AWS AppSync for live chat, notifications, and data sync.
Data Pipeline & ETL Backend
Create ETL pipelines with Apache Airflow, dbt, and Snowflake for data ingestion, transformation, and analytics.
Authentication & Authorization Backend
Implement OAuth 2.0, SAML, or custom JWT-based auth with Okta, Auth0, or Keycloak for multi-tenant access control.
Serverless Backend
Deploy serverless functions on AWS Lambda or Cloudflare Workers with DynamoDB or Firestore for auto-scaling backends.
Backend for Mobile Apps
Build mobile-optimized backends with Firebase, AWS Amplify, or custom Node.js APIs that handle push notifications and offline sync.
We build for every business type.
SaaS Platforms
Fintech & Payments
Healthcare & Life Sciences

Why Expert Backend App Development Services Matter
Your backend is the engine of your product. A poorly built one costs you users and revenue.
A slow API response time of over 500ms causes 50% of users to abandon a mobile app. IRPR builds backends that respond in under 100ms for 95% of requests, using caching layers with Redis and CDN edge caching on CloudFront.
We design for scale from day one. Our backend architectures handle 10x traffic spikes without downtime, using auto-scaling groups on AWS ECS and read replicas on PostgreSQL. Every deployment includes automated load testing with k6 to validate performance.
IRPR vs Generic Development Shops
Not all backend agencies deliver the same quality. Here is the difference.
Generic shops often use boilerplate code that is not optimized for your use case. They skip load testing, ignore security patches, and deliver untested APIs that break under load.
IRPR assigns only senior backend engineers with 8+ years of experience. Every API endpoint gets unit tests, integration tests, and contract tests. We ship with a full monitoring stack including Sentry, Datadog, and PagerDuty alerts.
- Uses junior developers for backend work
- No load testing before launch
- No CI/CD pipeline
- No monitoring or alerting
- Unclear ownership of code
- Hourly billing with scope creep
- Senior engineers with 8+ years experience
- Automated load testing with k6
- Full CI/CD on GitHub Actions or GitLab CI
- Sentry + Datadog + PagerDuty monitoring
- Full source code ownership from day one
- Fixed price per project, no surprises
Our Backend Development Process
We follow a 4-phase process that turns your idea into a production backend.
Phase 1 is the Idea phase where we map out all endpoints, data models, and integrations. Phase 2 is Roadmap where we deliver a fixed-price contract with a detailed technical specification.
Phase 3 is Product where we build and iterate in 2-week sprints. Phase 4 is Release where we deploy to production with monitoring and documentation.
What Ships with Every Backend Project
Every backend project includes these deliverables by default.
We do not hand over raw code. We deliver a complete production-ready system with infrastructure, monitoring, and documentation. Your team can take over immediately or we can continue maintaining it.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with automated tests and deployments
- API documentation with OpenAPI 3.0 (Swagger)
- Load testing report with k6 results
- Sentry error tracking and Datadog performance monitoring
- Database schema and migration scripts (PostgreSQL, MySQL, or MongoDB)
- Docker containers with docker-compose for local development
- Infrastructure as code with Terraform or AWS CDK
- Security audit report (OWASP top 10 check)
- Post-launch support for 30 days
What we ship in this practice.
SaaS Subscription API
Built a billing and subscription management API for a B2B SaaS platform. Integrated Stripe Billing, handled 50,000 concurrent users, and reduced failed payments by 30% using dunning logic. Tech stack: Node.js, PostgreSQL, Stripe, Redis.
Real-Time Chat Backend
Developed a WebSocket-based chat backend for a telehealth app. Supported 10,000 simultaneous connections with sub-200ms message delivery. Tech stack: Socket.io, Redis Pub/Sub, MongoDB, AWS ECS.
Ecommerce Order Processing
Designed a microservices backend for order processing and inventory management. Scaled to 1 million orders per month with 99.95% uptime. Tech stack: Go, RabbitMQ, PostgreSQL, Kubernetes.
Fintech Payment Gateway
Built a PCI-DSS compliant payment gateway API that processes 10,000 transactions per minute. Integrated with Stripe, Plaid, and ACH networks. Tech stack: Python FastAPI, PostgreSQL, AWS Lambda, Stripe.
Real Estate MLS API
Created a backend that aggregates MLS data from 50+ sources, normalizes it, and serves it via REST API. Reduced data sync time from 4 hours to 15 minutes. Tech stack: Node.js, PostgreSQL, Kafka, AWS S3.
Media Streaming Backend
Built a video streaming backend with adaptive bitrate transcoding and CDN delivery. Handled 500,000 daily active users with 99.9% availability. Tech stack: Python, FFmpeg, AWS MediaConvert, CloudFront, DynamoDB.
Why teams hire us.
Fixed price, not hourly
Every backend project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
We assign engineers with 8+ years of backend experience. No juniors, no outsourcing. Every team member has built and scaled production systems handling millions of requests.
Production-ready from day one
We ship with CI/CD, monitoring, load testing, and documentation. Your backend is ready for production on day 1 of the Release phase, not after months of fixes.
Full code ownership
You own every line of code, every Dockerfile, every Terraform script. No licensing fees, no vendor lock-in. Your team can take over maintenance immediately after launch.
Compliance built in
We build backends that pass HIPAA, PCI-DSS, and SOC 2 audits. We implement encryption at rest and in transit, audit logs, and role-based access control by default.
200+ products shipped
We have shipped over 200 backend systems across 50 countries. Our process is proven, our engineers are battle-tested, and our clients include funded startups and Fortune 500 companies.
