Leading Backend API Development ConsultantsAPI Development
We build production-grade APIs that scale to millions of requests. 200+ products shipped, 8-12 week delivery, fixed pricing.
IRPR is a team of senior backend engineers who build APIs for companies that need reliability and speed. We use Node.js, Python, Go, and .NET to create REST, GraphQL, and gRPC endpoints that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, caching, and database design. Our APIs pass HIPAA, PCI-DSS, and SOC 2 audits.
CTOs hire us when their in-house team is overloaded. Startup founders hire us to build their first production API. Enterprise architects hire us to modernize legacy backend systems. Product managers hire us to ship integrations with Stripe, Salesforce, and HubSpot.
Types of software we ship.
REST API Development
Stateless endpoints with JSON responses. Built with Express.js or FastAPI. Includes OpenAPI documentation and Postman collections.
GraphQL API Development
Single endpoint with flexible queries. Built with Apollo Server or Hasura. Includes schema stitching and resolver optimization.
Microservices API Architecture
Decoupled services communicating via gRPC or message queues. Uses Docker, Kubernetes, and NATS for event-driven workflows.
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP API. Includes error handling and retry logic.
Real-Time API Development
WebSocket and Server-Sent Events endpoints for live data. Built with Socket.io or AWS AppSync. Used for chat, notifications, and dashboards.
API Gateway and Rate Limiting
Centralized gateway with authentication, throttling, and logging. Uses Kong, AWS API Gateway, or NGINX. Supports OAuth2 and JWT.
Backend-as-a-Service (BaaS) API
Custom BaaS with user management, file storage, and push notifications. Built with Firebase or Supabase. Includes admin dashboard.
Legacy API Modernization
Migrate SOAP or monolithic APIs to REST or GraphQL. Includes database migration, load testing, and zero-downtime deployment.
We build for every business type.

Why Leading Backend API Development Consultants Matter
A poorly designed API costs you time, money, and customers. Here is what IRPR delivers.
Every API we build starts with a Roadmap phase where we define endpoints, data models, and error handling. We use OpenAPI 3.0 to generate documentation automatically. Our APIs include rate limiting, caching with Redis, and database indexing for sub-50ms response times.
We test every endpoint with automated integration tests using Jest or Pytest. We deploy with CI/CD pipelines on GitHub Actions or GitLab CI. Each API ships with a monitoring dashboard using Datadog or New Relic.
Generic Dev Shop vs IRPR: The API Development Difference
Not all backend API development consultants deliver the same quality. Here is how IRPR stands apart.
Generic shops often skip documentation, ignore error handling, and deliver APIs that break under load. They use hourly billing and change scope without notice.
IRPR writes OpenAPI specs before writing code. We include rate limiting, retry logic, and structured error responses. Every API ships with a Postman collection and a monitoring dashboard.
- No API documentation
- No rate limiting
- No automated tests
- Hourly billing with scope creep
- No monitoring or alerts
- No CI/CD pipeline
- OpenAPI 3.0 docs from day one
- Rate limiting with Redis
- 100% test coverage on endpoints
- Fixed price, no surprises
- Datadog monitoring included
- GitHub Actions CI/CD
Our API Development Process: From Idea to Production
We follow a 4-phase process that guarantees a production-ready API in 8-12 weeks.
Phase 1: Idea. We map your business logic to API endpoints. We define data models, authentication flows, and integration points. You get a detailed Roadmap document with wireframes and endpoint specs.
Phase 2: Roadmap. We finalize the tech stack, database schema, and deployment architecture. We set up the CI/CD pipeline and monitoring tools. You get a fixed price quote.
What Ships With Every API Project
Every API we build includes these deliverables by default. No hidden costs.
You get full source code in your GitHub or GitLab repo. You get a CI/CD pipeline that runs tests and deploys automatically. You get a monitoring dashboard with alerts for errors and latency spikes.
We include a Postman collection with example requests for every endpoint. We write integration tests that cover happy paths and error cases. We provide a deployment guide and runbook.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- OpenAPI 3.0 documentation
- Postman collection with examples
- Automated integration tests (Jest/Pytest)
- Datadog monitoring dashboard
- Sentry error tracking
- Rate limiting with Redis
- Database schema and migration scripts
- Deployment runbook and architecture diagram

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Every engineer at IRPR has 8+ years of backend experience. We do not outsource or use junior developers. Your API is built by someone who has shipped production systems at scale.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without cutting corners. You get a working API with tests, docs, and monitoring.
Full code ownership
You own all source code, documentation, and infrastructure. No licensing fees, no vendor lock-in. You can take the code to any team after we deliver.
Compliance built in
We build APIs that pass HIPAA, PCI-DSS, and SOC 2 audits. We include encryption, access controls, and audit logging by default. No retrofitting compliance later.
Post-launch support
We provide 30 days of post-launch support for every API project. We fix bugs, answer questions, and help your team take over. After that, we offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
