Top Backend API Development CompanyBackend API
We build secure, high-performance APIs for web and mobile apps. Get a fixed-price quote in 2 weeks.
IRPR is a top backend API development company. We build production-grade APIs using Node.js, Python, Go, and Rust. Every endpoint is designed for security, scalability, and auto-generated documentation.
Each custom API ships in 8-12 weeks with fixed pricing from $80K-$250K. Our APIs meet HIPAA, PCI-DSS, and SOC 2 compliance requirements. We handle authentication, rate limiting, and CI/CD pipelines out of the box.
We work with CTOs decoupling frontend from legacy backends, founders launching SaaS MVPs that need a reliable API layer, enterprise teams migrating from monoliths to microservices, and ecommerce platforms requiring custom integrations with Stripe, Shopify, or Salesforce.
Types of software we ship.
REST API development
Clean RESTful endpoints with OpenAPI specs, built on Express or FastAPI. Ideal for CRUD-heavy applications and third-party integrations.
GraphQL API development
Flexible GraphQL backends with Apollo Server or Hasura. Clients query exactly what they need, reducing overfetching by 30%.
Microservices API layer
Event-driven microservices with Kafka or RabbitMQ. Each service is independently deployable and scales on demand.
WebSocket API development
Real-time WebSocket servers using Socket.io or ws library. Achieve sub-100ms latency for chat, live tracking, and notifications.
Third-party API integration
Connect your product to Stripe, Salesforce, HubSpot, or Twilio. We handle OAuth, webhooks, and error retries with idempotency.
Custom API gateway
Deploy a gateway using Kong or Envoy to unify multiple backends. Add authentication, rate limiting, and monitoring in one place.
API security layer
Implement JWT, OAuth 2.0, API keys, and IP whitelisting. Penetration tested with OWASP Top 10 coverage.
API documentation portal
Auto-generated Swagger or Redoc docs with interactive try-it-out features. Published as static sites on AWS S3 or Netlify.
We build for every business type.
SaaS companies
Healthcare
Fintech
Ecommerce

Why IRPR is a top backend API development company
We deliver APIs that handle millions of requests with 99.9% uptime.
Every API we build starts with a 2-week Roadmap phase. We define endpoints, data models, authentication flows, and performance targets before writing any code. The result is a detailed specification that becomes the contract for fixed pricing.
Our APIs are deployed on AWS, GCP, or Azure using infrastructure as code (Terraform). Each deployment includes auto-scaling, load balancing, and distributed tracing with Datadog or Sentry. We monitor error rates, latency p99, and throughput in real time.
How IRPR differs from generic dev shops
Most agencies charge by the hour and deliver incomplete code. We don't.
Generic dev shops often have junior engineers learning on the job. They underbid, then scope-creep their way to hourly overages. You end up with a messy codebase, no documentation, and no SLA.
IRPR works differently. Every project is staffed with senior engineers only (8+ years experience). We fix the price in week 2, deliver every feature in the spec, and hand over full source code with CI/CD, monitoring, and docs.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- No CI/CD or monitoring setup
- Code ownership unclear
- Support ends at handoff
- Fixed price from the start
- Senior engineers only (8+ yr avg)
- HIPAA, PCI, SOC 2 built in
- CI/CD, Sentry, Datadog included
- Full code ownership
- 12-month warranty on defects
Our API development process in 4 phases
From whiteboard to production in 8-12 weeks.
We follow a structured process that eliminates surprises. Each phase ends with a deliverable that you review and approve before we move to the next.
The Roadmap phase is especially important. It costs a flat $X (typical $8K-$15K) and produces a complete API specification, cost estimate, and timeline. You can walk away after this phase with no further obligation.
Everything that ships with your API
No hidden line items. Every deliverable is listed here.
When you hire IRPR as your top backend API development company, you get a complete production-ready system. We don't cut corners or leave skeleton code. Everything listed below is included in the fixed price.
- Source code in your Git repository (private, full history)
- CI/CD pipeline on GitHub Actions or GitLab CI
- Auto-generated API documentation (Swagger/OpenAPI)
- Sentry error tracking and performance monitoring
- Dockerized services with docker-compose for local dev
- Cloud infrastructure scripts (Terraform for AWS/GCP/Azure)
- Load testing report using k6 or Artillery
- Postman collection for manual testing
- Environment variable management (dotenv + secrets manager)
- README with setup instructions and architecture diagram
What we ship in this practice.
Custom REST API for a fintech platform
We built a PCI-compliant REST API for processing payments across 12 currencies. Stack: Node.js, PostgreSQL, Stripe Connect. Reduced transaction latency by 40% and passed SOC 2 audit.
GraphQL backend for an ecommerce store
Replaced a REST API with GraphQL (Apollo Server, Next.js frontend). Query times dropped from 800ms to 200ms. Team reported 3x faster feature development.
Real-time API for logistics tracking
Built a WebSocket-based API using Go and Redis. Tracks 10,000+ vehicles in real time with sub-100ms updates. Integrated with Google Maps and Twilio SMS.
API gateway unifying 15 microservices
Deployed Kong API gateway for a SaaS client with 15 services. Added OAuth 2.0, rate limiting, and unified logging. Reduced service-to-service latency by 60%.
FHIR-compliant API for a health tech startup
Developed a FHIR R4 API using Python (FastAPI) and PostgreSQL. Passed HIPAA security assessment in 3 weeks. Handles 1M patient records with 99.9% uptime.
Third-party integration API for a media platform
Connected a video streaming app with 6 third-party APIs (Stripe, YouTube, Vimeo, Mailchimp, Salesforce, Algolia). Automated webhook handling with 100% idempotency.
Why teams hire us.
Fixed price, not hourly
We quote a fixed price in week 2 of the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a line of code.
Senior engineers only
Every project is staffed with engineers who have 8+ years of experience. We don't staff juniors or offshore teams. Our lead engineers have built APIs for Fortune 500 companies and Y Combinator startups.
200+ products shipped across 50+ countries
We have delivered over 200 custom software products to clients in 50+ countries. Many of those products are API-first backends serving hundreds of thousands of users.
Compliance built in
Every API is designed with HIPAA, PCI-DSS, or SOC 2 controls from day one. We use encryption, audit logs, and role-based access. Our clients pass audits on their first attempt.
12-week delivery guarantee
Over 98% of our projects deliver on schedule. We achieve this through strict scope control, weekly demos, and a fixed timeline that we commit to in writing.
Full code ownership
You own every line of code we write. We give you the source code, infrastructure scripts, and CI/CD configurations. No licensing fees, no vendor lock-in.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
