Affordable Backend API Development DevelopersAPI Development
Senior engineers build your backend API in 8-12 weeks. Fixed pricing starts at $80K.
IRPR builds backend APIs using Node.js, Python, Go, and PostgreSQL. We handle GraphQL, WebSockets, and event-driven architecture for any scale.
We ship a fully functional API in 8-12 weeks with fixed pricing from $80K to $250K. Every API includes CI/CD, error tracking, and compliance documentation for HIPAA or PCI-DSS.
Founders hire us to launch SaaS products. CTOs hire us to replace legacy systems. Product managers hire us to add an API layer to existing software. We also work with agencies that need white-label backend development.
Types of software we ship.
RESTful API for mobile apps
Public and private REST endpoints with JWT auth, rate limiting, and OpenAPI docs. Integrates with AWS API Gateway.
GraphQL API for front-end teams
Single endpoint, typed schema, resolver-based data fetching. Uses Apollo Server and PostgreSQL or MongoDB.
Microservices API backend
Decoupled services with message queues (RabbitMQ, Kafka) and API gateways. Each service scales independently.
Payment processing API
Handles Stripe, Square, Braintree integrations. Built with idempotency keys and webhook replay for retail or SaaS.
Real-time data API (WebSockets)
Low-latency bidirectional communication for live chat, notifications, or dashboards. Uses Socket.IO or native WebSockets.
Third-party API integration layer
Unified interface for multiple external services (Salesforce, HubSpot, QuickBooks). Handles auth and rate limits.
Admin dashboard API
Backend endpoints for internal tools, CRUD operations, role-based access, audit logs. Built with Express or Fastify.
Data aggregation and analytics API
ETL pipelines from multiple sources, cached query results, and paginated responses. Uses Redis and TimescaleDB.
We build for every business type.
SaaS companies
Ecommerce brands
Healthcare organizations
Fintech startups
Logistics companies
Why affordable backend API development developers matter
A solid backend API is the foundation for every scalable product.
Without a well-architected API, your mobile app or web app will break under load. IRPR builds APIs that handle 1000+ requests per second with sub-200ms response times. We use Node.js, Go, or Python depending on your data and concurrency needs.
Our team of senior engineers writes automated tests, sets up monitoring with Sentry and DataDog, and documents every endpoint using Swagger. You get a production-ready API in 8-12 weeks with a fixed price. No surprises.
The IRPR difference for backend API development
Most dev shops build slow, buggy APIs that cost twice the estimate.
Generic shops assign junior developers who learn on your dime. They bill hourly and change requirements mid-flight. You end up with an API that crashes under 100 concurrent users and takes months to deploy.
IRPR assigns senior engineers only. We define the entire API contract in the Roadmap phase (week 2). Every endpoint, request model, and response format is locked before a single line of code is written.
- Junior devs with 1-2 years experience
- Hourly billing with vague scope
- No automated tests
- No CI/CD pipeline
- APIs crash under 100 concurrent users
- Unclear ownership of code
- Senior engineers with 5+ years each
- Fixed price from Roadmap phase
- 100% test coverage on critical endpoints
- CI/CD with GitHub Actions and AWS
- API handles 1000+ concurrent users
- Full source code ownership
How we build your affordable backend API
Our process eliminates guesswork and delays.
We follow a four-phase approach that has shipped over 200 products. Each phase has a clear deliverable and a fixed timeline. You know exactly when you will get your API and how much it costs.
The Roadmap phase is the most important. IRPR creates a detailed API contract, data model, and endpoint list. You approve it before we start building. This removes all ambiguity.
What ships with your backend API
Every project includes production-ready infrastructure.
You get more than just code. We deliver a complete system that is deployable on day one. Every project includes CI/CD, error tracking, and monitoring out of the box.
IRPR also provides compliance documentation for HIPAA or PCI-DSS if needed. We make sure your API meets the security standards required by your industry.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- DataDog performance monitoring
- Swagger/OpenAPI documentation
- Database migration scripts
- Docker containers for local development
- Deployment playbook for AWS or GCP
- API authentication (JWT or OAuth2)
- Load testing report for 1000+ users
What we ship in this practice.
SaaS subscription analytics API
Built a RESTful API that ingests 2 million events per month from Stripe and HubSpot. Reduced report generation time from 1 hour to 2 minutes. Stack: Node.js, PostgreSQL, Redis.
Telehealth appointment booking API
Developed a HIPAA-compliant API for scheduling, video calls, and patient records. Handles 500 concurrent bookings without slowdown. Stack: Python, FastAPI, AWS Lambda.
Fintech payment reconciliation API
Created a PCI-DSS compliant API that matches bank transactions to invoices. Cut reconciliation time by 15 hours per week. Stack: Go, PostgreSQL, Stripe Connect.
Ecommerce inventory aggregation API
Built a GraphQL API that syncs inventory across 3 warehouses and Shopify. Reduced overselling by 95% in 30 days. Stack: Node.js, Apollo, MongoDB.
Real estate MLS integration API
Designed a microservices API that pulls listing data from 5 MLS providers. Queries return in 300ms average. Stack: Node.js, PostgreSQL, Redis, WebSockets.
Logistics route optimization API
Developed a REST API that calculates optimal delivery routes for 200+ stops. Reduced fuel costs by 18% for a fleet of 50 trucks. Stack: Python, FastAPI, Google Maps API.
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. You know the cost before we write a single line of code.
Senior engineers only
IRPR does not use junior developers. Every engineer on your project has 5+ years of experience building production APIs. We skip the learning curve.
12-week delivery guarantee
We ship your minimum viable API in 8-12 weeks. If we miss a sprint milestone, IRPR adds engineers at no extra cost. 98% of our projects deliver on time.
Full code ownership
You own 100% of the source code, documentation, and infrastructure from day one. No licensing fees, no lock-in, no hidden costs.
Built for compliance
IRPR builds APIs that meet HIPAA, PCI-DSS, SOC 2, and FERPA standards. We include audit logs, encryption at rest, and access controls in every project.
Post-release support included
After launch, IRPR provides 30 days of free support for bug fixes and minor tweaks. We also offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
