Top API Development Partner for Scalable SystemsAPI Development
We build secure, high-performance APIs that connect your stack. Ship a production-grade API in 8-12 weeks with a fixed price.
IRPR builds custom APIs that power web apps, mobile backends, and microservices. We use Node.js, Go, Python, and PostgreSQL with automated CI/CD pipelines on GitHub Actions.
We ship API projects in 8-12 weeks with fixed prices from $80K to $250K. Every API includes OAuth 2.0 authentication, rate limiting, OpenAPI 3.0 specs, and Datadog monitoring.
We work with founders building SaaS platforms, CTOs integrating third-party tools, product managers launching mobile backends, and enterprise teams migrating to microservices.
Types of software we ship.
REST API
Stateless HTTP APIs using Express.js, Django REST, or FastAPI. Includes pagination, filtering, and versioning.
GraphQL API
Flexible data queries with Apollo Server (Node.js) or Ariadne (Python). Reduces over-fetching by 40% on average.
gRPC API
High-performance RPC using Protocol Buffers. Used for internal microservices with sub-10ms latency.
WebSocket API
Real-time bidirectional communication with Socket.IO or ws library. Supports 10K concurrent connections per node.
Third-party API Integration
Connect Stripe, Salesforce, HubSpot, or any REST/SOAP API. We handle OAuth flows and webhook parsing.
API Gateway
Centralized gateway using Kong or AWS API Gateway with rate limiting, JWT validation, and request transformation.
Internal Microservices API
Async messaging with RabbitMQ or Kafka. Services communicate via NATS with circuit breakers and retry logic.
Public API Product
Developer portal with API keys, usage analytics, and documentation via Swagger. Supports monetization and versioning.
We build for every business type.

Why choose IRPR as your top API development partner
We have shipped 200+ production APIs across every major industry.
Our APIs handle millions of requests per day with 99.9% uptime. From fintech to healthcare, we design for security and scale from day one. Every API goes through OWASP security review and load testing.
We use OpenAPI 3.0 to auto-generate interactive documentation. That means your frontend team and integrators can start coding in minutes, not days. Our average API project ships in 12 weeks.
How we differ from generic API shops
Most dev shops treat APIs as side projects. We treat them as core infrastructure.
Generic shops often skip security reviews and proper documentation. They bill by the hour and rarely provide monitoring. The result is an API that breaks under load and leaves your team guessing.
IRPR delivers APIs that are documented, monitored, and secured from day one. We provide OpenAPI specs, Datadog dashboards, and a deployment runbook. You get full ownership of the code and infrastructure.
- Hourly billing with no cost ceiling
- Unclear API spec changes mid-project
- No security audit or penetration testing
- Minimal or no documentation
- No production monitoring setup
- Code ownership not clearly defined
- Fixed price agreed in Roadmap phase (week 2)
- OpenAPI 3.0 spec written before any code
- OWASP security audit and rate limiting
- Auto-generated Swagger docs and Postman collection
- Datadog monitoring and alerting configured
- Full code ownership - you own everything
Our API development process in 4 phases
From spec to production in 12 weeks.
We start with a 2-week Discovery & Spec phase to map endpoints, data models, and authentication flows. Then we architect the system for security and scalability.
Implementation is iterative with weekly demos. Testing covers unit, integration, and load tests. Launch includes a deployment runbook and monitoring setup.
What you get with each API delivery
Every API project ships with these deliverables.
You receive everything needed to run and maintain your API without depending on us. All artifacts are stored in your own repositories and accounts.
- Source code in your private GitHub repository
- OpenAPI 3.0 specification file
- CI/CD pipeline on GitHub Actions or GitLab CI
- Postman collection with all endpoints
- OAuth 2.0 integration with your identity provider
- Rate limiting configuration (e.g., 100 req/min per key)
- Datadog monitoring dashboard with error tracking
- Unit and integration tests (90%+ coverage)
- Deployment runbook and environment setup guide
What we ship in this practice.

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. Our average API project costs $80K-$250K.
12-week delivery guarantee
We ship 98% of projects on time. Our 4-phase process (Spec, Architect, Build, Launch) takes 12 weeks on average. You get a working API in production, not a promise.
Full code ownership
You own every line of code we write. There are no license fees, no ongoing royalties, and no vendor lock-in. All source code, configs, and documentation are in your repository.
Security-first development
Every API we build gets an OWASP Top 10 security review, rate limiting, and encrypted data storage. For fintech we implement PCI-DSS controls; for healthcare, HIPAA compliance is built in from day one.
OpenAPI documentation by default
We write the OpenAPI 3.0 spec before writing any code. You get interactive Swagger UI docs, a Postman collection, and auto-generated client SDKs for your frontend or mobile teams.
24/7 monitoring and support
We set up Datadog monitoring, PagerDuty alerts, and structured logging before launch. Post-launch we provide 2 weeks of hyper-care and ongoing support options. Our average response time is under 15 minutes.
