Experienced Backend API Development TeamBackend API
We build REST, GraphQL, and gRPC APIs for SaaS platforms and data-heavy apps. Get a dedicated team that ships in 8-12 weeks with fixed pricing.
IRPR builds production-grade backend APIs using Node.js, Python, Go, and .NET. We design RESTful endpoints, GraphQL schemas, and gRPC services that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price range of $80K-$250K. We handle authentication, rate limiting, caching, database design, and deployment. Our APIs meet SOC 2, HIPAA, and PCI-DSS compliance where needed.
Companies hire us when they need an experienced backend API development team to replace a stalled in-house project, to build a scalable SaaS backend from scratch, or to integrate third-party APIs like Stripe, Twilio, and Salesforce. Typical buyers are CTOs, VP of Engineering, product managers, and technical founders.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with OpenAPI 3.0 specs, JWT auth, and PostgreSQL/MySQL. Perfect for mobile backends and third-party integrations.
GraphQL API Development
Design GraphQL schemas with Apollo Server, resolvers, and DataLoader for efficient querying. Used for real-time dashboards and complex data aggregations.
Microservices Backend
Decompose monolithic apps into microservices with Docker, Kubernetes, message queues (RabbitMQ, Kafka), and API gateways (Kong, Envoy).
Real-Time API Development
Build WebSocket and SSE-based APIs for live updates. Use Socket.io, Redis Pub/Sub, and Firebase for chat, notifications, and live data.
Third-Party API Integration
Integrate Stripe, Twilio, Salesforce, HubSpot, and 200+ other APIs. Handle OAuth flows, webhooks, and rate limiting.
API Security & Auth
Implement OAuth 2.0, OpenID Connect, API keys, and role-based access control (RBAC). Audit logs and rate limiting included.
Backend-as-a-Service (BaaS)
Build a custom BaaS with Firebase-like features: auth, storage, real-time DB, serverless functions. Deploy on AWS Lambda or Cloudflare Workers.
Data Pipeline APIs
Create ETL APIs that ingest, transform, and serve data from sources like Snowflake, BigQuery, and S3. Use Apache Kafka or Airflow for orchestration.
We build for every business type.

Why Hire an Experienced Backend API Development Team
We have built 200+ APIs for companies in 50+ countries.
Our team of senior engineers has delivered APIs for fintech platforms handling $10M+ in monthly transactions, healthcare systems with HIPAA-compliant data pipelines, and ecommerce backends processing 10,000+ orders per day. Every API is designed for scalability, security, and maintainability.
We follow a proven process: Idea (week 1), Roadmap (week 2), Product (weeks 3-10), Release (weeks 11-12). During Roadmap we spec out every endpoint, data model, and integration point so you know exactly what you get and what it costs.
The Difference Between IRPR and a Generic Dev Shop
Not all backend teams are equal. Here is how we compare.
Generic dev shops often start coding without a clear spec, leading to scope creep and missed deadlines. They use junior developers and charge by the hour, making costs unpredictable.
IRPR assigns senior engineers only, delivers a fixed-price quote after a 2-week Roadmap, and ships in 8-12 weeks. We own the code quality with CI/CD, automated tests, and security audits.
- Starts coding without a detailed spec
- Uses junior developers with limited API experience
- Charges by the hour with no cost cap
- No automated testing or CI/CD pipeline
- No security audit or compliance documentation
- Code ownership unclear until project ends
- Delivers a full API spec in the Roadmap phase (week 2)
- Senior engineers with 10+ years of backend experience
- Fixed price quoted upfront, no hourly billing
- Automated tests (unit, integration, load) and CI/CD on GitHub Actions
- Security audit for OWASP Top 10 and compliance docs for SOC 2/HIPAA
- You own all source code from day one
Our Process for Building Your Backend API
We follow a structured 4-phase process.
Phase 1: Idea - We align on your business goals, user stories, and technical constraints. This takes 1 week.
Phase 2: Roadmap - We produce a detailed API spec with endpoints, data models, auth flows, and integration points. You get a fixed price and timeline. This takes 1 week.
What Ships With Your Backend API
Every project includes these deliverables by default.
We don't just hand over code. You get a complete production-ready system.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Automated unit, integration, and load tests (Jest, Mocha, k6)
- API documentation with Swagger/OpenAPI or GraphQL Playground
- Postman collection for manual testing
- Docker Compose setup for local development
- Monitoring and alerting with Datadog or Sentry
- Security audit report (OWASP Top 10)
- Deployment guide with environment variables and secrets management
- 30-day post-launch support for bug fixes and minor changes
