Leading Custom Backend Development ServicesBackend Development
We build server-side systems that handle millions of requests. Fixed pricing from $80K, delivered in 12 weeks.
IRPR builds custom backend systems using Node.js, Python (Django, FastAPI), Go, and PostgreSQL. We design RESTful and GraphQL APIs, microservices architectures, and real-time data pipelines for products that serve 10,000+ concurrent users.
Every project ships with a fixed price - no hourly billing. MVPs take 8 to 12 weeks and cost $80,000 to $250,000. We handle compliance: HIPAA for healthcare, PCI-DSS for payments, SOC 2 for SaaS platforms.
Founders hire us to replace a broken monolithic backend with a scalable microservice architecture. CTOs hire us to build their core API before their own team expands. Product managers hire us to add a real-time data sync layer to an existing app.
Types of software we ship.
RESTful API Development
Build stateless REST APIs with Node.js and Express. Includes JWT auth, rate limiting, and Swagger documentation.
GraphQL Backend
Create a single GraphQL endpoint with Apollo Server. Resolves nested queries and supports real-time subscriptions via WebSocket.
Microservices Architecture
Split a monolith into separate services communicating via gRPC or message queues. Each service scales independently.
Real-Time Data Pipeline
Process streaming data with Apache Kafka or Redis Streams. Used for live dashboards, notifications, and event logging.
Serverless Backend
Deploy functions on AWS Lambda or Google Cloud Functions. Pay per execution, auto-scale to zero, no server management.
Authentication and Authorization System
Implement OAuth 2.0, SAML, or custom JWT flows. Integrates with Okta, Auth0, or Azure AD for enterprise SSO.
Payment Processing Backend
Handle Stripe and Braintree webhooks for subscriptions, invoicing, and refunds. Includes idempotency keys and retry logic.
Database and Storage Layer
Design PostgreSQL schemas with migrations, read replicas, and connection pooling. Use S3 or Azure Blob for file storage.
We build for every business type.

Custom Backend Development That Ships Fast
We deliver production-ready backend code in 12 weeks.
Every project starts with a 1-week Roadmap phase. We define the API contract, data model, and deployment plan. You get a fixed price and a timeline before any code is written. No surprises.
Our senior engineers use TypeScript, Go, and Python. We deploy on AWS ECS or Kubernetes with CI/CD pipelines on GitHub Actions. Every service includes health checks, logging via Datadog, and error tracking via Sentry.
How We Build Backends Differently
We fix the problems that plague custom backend projects.
Most agencies start coding without a clear spec. They bill hourly and add features mid-project. Scope creep kills timelines and budgets.
IRPR does the opposite. We spec everything in the Roadmap phase. We write integration tests before the API. We deliver a complete backend with zero technical debt.
- Starts coding without a spec
- Bills hourly, no cap
- No automated tests
- Manual deployment
- No monitoring setup
- No documentation
- Writes API contract first
- Fixed price from Roadmap
- Integration tests for every endpoint
- CI/CD with GitHub Actions
- Datadog + Sentry monitoring
- OpenAPI docs auto-generated
Our Backend Development Process
Four phases from idea to production.
Phase 1 is the Roadmap: 1 week to define the data model, API endpoints, and deployment architecture. Phase 2 is Build: 6-10 weeks of writing code with daily commits and weekly demos.
Phase 3 is Release: we deploy to production with zero-downtime migrations. Phase 4 is Handoff: you get full source code, CI/CD pipelines, and a 30-day warranty for any bugs.
What Ships With Every Backend
Every project includes these deliverables by default.
You own everything. Source code in your GitHub repo, deployed on your AWS account. No lock-in, no recurring license fees.
We include everything needed to run in production: monitoring, logging, error tracking, and automated deployments. Your team can take over immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker Compose for local development
- PostgreSQL schema with migrations
- API documentation via OpenAPI/Swagger
- Sentry error tracking
- Datadog performance monitoring
- Health check endpoints
- Load testing report (k6)
- 30-day warranty for any bugs
What we ship in this practice.
SaaS Subscription Backend
Built a multi-tenant billing API for a B2B SaaS company. Handles 50,000 active subscriptions with Stripe webhooks. Tech stack: Node.js, PostgreSQL, Redis, Stripe. Reduced billing errors by 95%.
Healthcare Patient API
Developed a HIPAA-compliant patient record API for a telehealth startup. Handles 10,000 patient records with encrypted storage. Tech stack: Python FastAPI, PostgreSQL, AWS KMS.
Ecommerce Order Pipeline
Built a real-time order processing pipeline for an online retailer. Integrates with Shopify, ShipStation, and QuickBooks. Processes 2,000 orders per hour. Tech stack: Node.js, RabbitMQ, MongoDB.
Real-Time Chat Backend
Created a WebSocket-based chat backend for a collaboration app. Supports 100,000 concurrent connections with message persistence. Tech stack: Go, Redis Streams, WebSocket.
Fintech Transaction Ledger
Built a double-entry ledger system for a payment processing startup. Handles 1 million transactions per day with full audit trails. Tech stack: Python Django, PostgreSQL, RabbitMQ.
IoT Data Ingestion Pipeline
Developed a scalable data ingestion service for a manufacturing client. Collects sensor data from 10,000 devices every 5 seconds. Tech stack: Go, Apache Kafka, InfluxDB.
Why teams hire us.
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. Our average project costs $80K-$250K.
Senior Engineers Only
No junior developers. Every engineer has 8+ years of experience with Node.js, Python, or Go. We skip the learning curve and deliver production-ready code from day one.
200+ Backends Built
We have shipped 200+ custom backend systems across 50 countries. Our code runs in production for healthcare, fintech, and ecommerce platforms.
Compliance Built In
We build HIPAA, PCI-DSS, and SOC 2 compliant backends. We handle audit logging, encryption at rest and in transit, and role-based access control by default.
Full Code Ownership
You own all source code, Docker images, and CI/CD pipelines. No licensing fees, no lock-in. Deploy on your own AWS or Azure account.
12-Week Delivery
Most MVPs ship in 8 to 12 weeks. We use TypeScript, Go, and Python with automated testing to move fast without breaking things.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
