Best Backend API Development ServicesAPI Development
We build production-grade APIs that handle millions of requests. Fixed price, 8-12 week delivery, full ownership.
IRPR builds the best backend API development services for companies that need reliable, scalable APIs. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to create REST and GraphQL APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code ownership and a CI/CD pipeline on GitHub Actions.
CTOs hire us when their in-house team is overloaded. Startup founders hire us to build their SaaS MVP. Enterprise product managers hire us to replace legacy APIs with modern microservices.
Types of software we ship.
REST API development
Stateless HTTP APIs with JSON responses. Built with Express.js or FastAPI. Includes OpenAPI 3.0 documentation.
GraphQL API development
Single endpoint with flexible queries. Built with Apollo Server or Hasura. Reduces over-fetching by 40% on average.
Microservices backend
Decoupled services communicating via gRPC or message queues. Each service scales independently on Kubernetes.
Real-time API development
WebSocket and Server-Sent Events for live data. Used for chat apps, live dashboards, and collaborative tools.
Third-party API integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP API. Includes retry logic and rate limiting.
API gateway and proxy
Centralized entry point with authentication, rate limiting, and caching. Built with Kong or AWS API Gateway.
Event-driven backend
Asynchronous processing with Apache Kafka or RabbitMQ. Handles spikes in traffic without dropping messages.
Serverless backend
Lambda functions and API Gateway for auto-scaling. Pay per request. Ideal for variable workloads and startups.
We build for every business type.
SaaS companies
Ecommerce brands
Healthcare organizations
Fintech companies
Logistics and supply chain
Why IRPR delivers the best backend API development services
We have shipped over 200 backend APIs for clients in 50+ countries. Every API is built for production from day one.
Our senior engineers average 10+ years of experience. We use Node.js, Python, Go, and Rust depending on your performance needs. Every API includes automated tests, rate limiting, and monitoring with Datadog or Sentry.
We follow a strict 4-phase process: Idea (week 1), Roadmap (week 2), Product (weeks 3-10), Release (weeks 11-12). You get a fixed price after the Roadmap phase. No surprises.
Generic dev shops vs IRPR: the real difference
Most agencies promise custom APIs but deliver copy-paste code with no documentation. IRPR builds APIs that your team can maintain and scale.
We have seen clients waste $50K on APIs that crash under 100 concurrent users. Our APIs handle 10,000+ requests per second because we design for scale from the start.
Every API ships with OpenAPI 3.0 docs, Postman collections, and a runbook for your ops team. You get full ownership of the code and infrastructure.
- No API documentation
- No load testing
- No CI/CD pipeline
- No error tracking
- No rate limiting
- No security audit
- OpenAPI 3.0 docs included
- Load tested to 10K+ req/s
- GitHub Actions CI/CD
- Sentry error tracking
- Rate limiting and throttling
- OWASP security review
How we build your backend API in 12 weeks
Our 4-phase process turns your idea into a production-ready API with no scope creep.
Phase 1 (Idea): We map your requirements, data models, and API endpoints in a 2-day workshop. You get a detailed specification document.
Phase 2 (Roadmap): We create a fixed-price proposal with a timeline, tech stack, and milestone schedule. You approve before any code is written.
What ships with every backend API
You get more than just code. Every API includes the tools your team needs to operate and scale.
We ship everything your ops team needs: CI/CD pipeline, monitoring dashboards, error tracking, and a runbook. No hand-waving, no 'we will add that later'.
Your developers get a Postman collection, OpenAPI 3.0 spec, and a local development environment with Docker Compose. They can start contributing on day one.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog or CloudWatch monitoring
- OpenAPI 3.0 documentation
- Postman collection with examples
- Docker Compose local dev setup
- Load test results (k6 or Artillery)
- Security audit report (OWASP top 10)
- Runbook for on-call engineers
What we ship in this practice.
SaaS subscription management API

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after 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
Our team averages 10+ years of backend experience. No junior developers, no offshore outsourcing. Every engineer has shipped production APIs for companies like Stripe, AWS, and Netflix.
Full code ownership
You own every line of code we write. No licensing fees, no vendor lock-in. We put the source code in your GitHub repo from day one.
Production-ready from day one
Every API ships with CI/CD, monitoring, error tracking, and load testing. Your ops team can deploy and maintain the API without calling us.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture from the start. No retrofitting, no last-minute audits.
12-week delivery guarantee
