Backend API Development CompanyAPI Development
We build production-grade REST and GraphQL APIs for startups and enterprises. Ship your backend in 8-12 weeks with a fixed price.
IRPR builds custom backend APIs using Node.js, Python, and Go. We use Express, FastAPI, and Gin for RESTful services, and Apollo for GraphQL. Every API ships with automated testing, CI/CD, and infrastructure-as-code.
We deliver a fully functional API with source code, CI/CD pipelines on GitHub Actions, and deployment on AWS or GCP. Our fixed-price projects run 12 to 14 weeks and cost between $80,000 and $250,000. We ensure HIPAA, PCI-DSS, and SOC 2 compliance when required.
CTOs scaling their platform hire us to handle massive traffic spikes. Startup founders trust us to build their MVP in weeks, not months. Product managers need our REST APIs to integrate third-party tools. Enterprise architects engage us to decouple monoliths into microservices.
Types of software we ship.
REST API Development
Stateless, cacheable REST endpoints using Express or FastAPI. Built for high traffic with rate limiting and JWT auth.
GraphQL API Development
Flexible GraphQL schemas with Apollo Server. Resolvers optimized to reduce over-fetching and under-fetching data.
Microservices Architecture
Decoupled services with event-driven communication using Kafka or RabbitMQ. Each service scales independently.
Serverless API Development
Lambda functions on AWS, Azure Functions, or Cloudflare Workers. Pay per request, auto-scale to zero.
API Integration Services
Connect your backend to Stripe, Salesforce, HubSpot, or any third-party API. Built-in retry logic and webhook handling.
API Management Platform
Centralized gateway with API keys, rate limiting, analytics, and developer portal using Kong or AWS API Gateway.
Data API Development
Read-optimized APIs for dashboards and reporting. Powered by PostgreSQL views, Redis caching, and Elasticsearch.
Webhook / Event API
Reliable webhook delivery system with idempotency keys, retry queues, and delivery logs using Redis and PostgreSQL.
We build for every business type.
SaaS Platforms
Fintech
Healthcare
Ecommerce
Mobile Apps
Why choose a backend api development company with a track record
IRPR has shipped 200+ backend APIs across 50 countries with 98% on-time delivery.
Every backend we build starts with a documented architecture. We choose the right stack for your scale - from Express for an MVP to Go with gRPC for high throughput. Our APIs are load-tested before release.
Your team gets full ownership: source code, infrastructure scripts, API documentation, and CI/CD pipelines. We use Sentry for error tracking and Datadog for monitoring so you see every failure in real time.
What separates IRPR from other backend api development companies
Most agencies charge by the hour and deliver inconsistent results. IRPR works differently.
We quote a fixed price after a 2-week Roadmap phase. You know the exact cost and timeline before we write a line of production code. No surprises, no scope creep.
Our engineers are senior only - no juniors learning on your project. Every API includes automated tests, CI/CD, and deployment playbooks. You get the code and can run it anywhere.
- hourly billing with estimates
- no architecture review
- manual testing only
- no CI/CD pipeline
- scalability added later
- code ownership unclear
- fixed price from Roadmap
- documented architecture
- automated test suite (90%+ coverage)
- CI/CD on GitHub Actions
- designed for scale from day one
- full IP ownership in your repo
How we build your backend API in 5 phases
Our process eliminates guesswork and delivers a production-ready API on time and on budget.
We start with a discovery sprint where we map every endpoint, data model, and third-party integration. You get a detailed API specification and a fixed price.
Development happens in 2-week sprints with daily standups and weekly demos. Deployment to staging happens by week 6, production release by week 12.
Every backend API ships with these deliverables
When we hand over the project, you get everything needed to run and extend the API yourself.
Our deliverables go beyond code. We provide documentation, infrastructure scripts, and monitoring dashboards so your team can operate independently.
All assets are in your GitHub repository. No proprietary frameworks, no locked-in tooling. You can deploy to any cloud provider.
- Source code in your private GitHub repo
- Postman collection for every endpoint
- API documentation (OpenAPI / Swagger)
- Database schema migration files
- CI/CD pipeline with GitHub Actions
- Error tracking with Sentry
- Logging with Datadog or CloudWatch
- Load testing report (k6 results)
- Deployment playbook (1-page runbook)
- SLA documentation and uptime guarantees
What we ship in this practice.
Payment Processing API for Fintech
Built a REST API that processes 5,000 transactions per minute using Node.js and Stripe. Reduced transaction failure rate by 70% and achieved PCI-DSS compliance. Tech: Node.js, Express, Stripe Connect, PostgreSQL.
Patient Data API for Healthcare
Developed a FHIR-compliant API that syncs patient records across 12 clinics. Cut sync time from 4 hours to 15 minutes. Tech: Python, FastAPI, HL7 FHIR, Azure SQL, HIPAA compliant.
Inventory API for Ecommerce
Created a real-time inventory API that integrates with Shopify and 3PL providers. Reduced inventory errors by 90% and enabled same-day fulfillments. Tech: Go, Gin, PostgreSQL, WebSockets.
User Management API for SaaS
Designed a GraphQL API for user authentication, roles, and multi-tenant data. Handles 10x user growth without performance degradation. Tech: Node.js, Apollo Server, Auth0, MongoDB.
Real-Time Notification API for Logistics
Built a WebSocket-based API delivering 1 million events per day for shipment tracking. Reduced latency from 5 seconds to under 200ms. Tech: Go, Redis Pub/Sub, WebSocket, AWS ECS.
Content Delivery API for Media
Created a video streaming API that serves 100TB of content per month. Implemented adaptive bitrate streaming with Cloudflare CDN. Tech: Node.js, AWS Elemental, Cloudflare, S3.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we start building.
Senior engineers only
Our team has 10+ years of experience each. No juniors or offshore interns. Every line of code is reviewed by at least 2 senior engineers before it ships.
Production-grade architecture
We design for scale from day one. APIs are load-tested to handle 10x your current traffic. We use caching, database indexing, and horizontal scaling patterns.
End-to-end ownership
You own all code, infrastructure scripts, and documentation. We transfer everything to your repos and cloud accounts. No lock-in, no recurring fees.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our teams have audited 20+ healthcare and fintech projects. Every API includes audit logs and encryption.
Continuous deployment
We set up CI/CD pipelines using GitHub Actions that run tests, lint, and deploy to staging on every commit. Production deployments are one click away.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
