Hire an experienced API development partnerAPI development
We build production-ready APIs in 8-12 weeks. Fixed price, no surprises, senior engineers only.
IRPR is an experienced API development partner that builds production-grade APIs for web apps, mobile backends, and microservices. We use REST, GraphQL, and gRPC with Node.js, Python, Go, and .NET.
Every API ships in 8-12 weeks with a fixed price starting at $80K. We handle authentication, rate limiting, documentation (OpenAPI), and monitoring (Datadog, Sentry). Compliance: HIPAA, PCI-DSS, SOC 2.
CTOs hire us to replace unreliable third-party integrations. Product owners hire us to ship their SaaS backend on time. Engineering VPs hire us to build internal APIs for data pipelines. Startups hire us to build their first API without hiring a full team.
Types of software we ship.
REST API development
Standard RESTful APIs with JSON payloads. Designed for high traffic, caching, and third-party consumption. Uses Express.js or FastAPI.
GraphQL API development
Flexible GraphQL APIs with Apollo Server or Hasura. Clients query only what they need. Reduces over-fetching and under-fetching.
gRPC API development
High-performance gRPC APIs with Protocol Buffers. For internal microservices, real-time streams, and low-latency systems. Uses Go or C#.
Webhook API development
Event-driven webhook systems that push data to external services. Includes retry logic, idempotency keys, and delivery receipts.
Third-party API integration
Integrate with Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP API. Handle auth, pagination, rate limits, and error handling.
API gateway and proxy
Build an API gateway with Kong, NGINX, or AWS API Gateway. Centralize auth, logging, throttling, and versioning.
Internal API for microservices
Design internal APIs for service-to-service communication. Use message queues (RabbitMQ, Kafka) for async workflows.
API documentation and SDK
Generate OpenAPI/Swagger docs automatically. Build client SDKs in JavaScript, Python, and Java for your customers.
We build for every business type.
SaaS platforms
ecommerce and retail
healthcare and fintech
real estate and logistics
media and edtech
What an experienced API development partner delivers
We ship more than code. Every API comes with documentation, monitoring, and a deployment pipeline.
IRPR has shipped 200+ APIs for clients in 50 countries. Each API includes automated tests, rate limiting, and error logging. We use OpenAPI 3.0 for documentation and Postman collections for testing.
Our APIs handle 10,000+ requests per second in production. We design for horizontal scaling from day one. Every endpoint has a defined SLA with 99.9% uptime target.
Generic dev shop vs experienced API development partner
Most agencies treat APIs as an afterthought. IRPR treats them as the product.
Generic shops write one-off endpoints with no documentation. They skip error handling and rate limiting. You get a black box that breaks in production.
IRPR designs APIs with versioning, idempotency, and backward compatibility. We write integration tests and monitor every endpoint. You get a reliable system you can build on.
- No API documentation shipped
- No rate limiting or throttling
- No automated tests for endpoints
- No monitoring or alerting
- No versioning strategy
- No security review for auth
- OpenAPI 3.0 docs included
- Rate limiting with Redis and NGINX
- Automated integration tests (Jest, Pytest)
- Datadog monitoring and Sentry alerts
- Semantic versioning with changelogs
- OAuth 2.0, JWT, API key auth
How we build your API in 8-12 weeks
Our process is structured so you see progress every week. No black boxes.
We start with a 2-week Roadmap phase where we define endpoints, data models, and auth flows. You get a detailed spec and a fixed price before any code is written.
Then we build in 2-week sprints. Each sprint ends with a deployable API. You test endpoints in staging. We handle deployment to AWS, GCP, or Azure.
What ships with every API
Every project includes everything you need to run, monitor, and maintain your API.
You get full ownership of the source code, CI/CD pipeline, and infrastructure as code. No lock-in. No ongoing fees.
We also ship a Postman collection, OpenAPI spec, and a runbook for your ops team. You can deploy to any cloud provider.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- OpenAPI 3.0 documentation
- Postman collection for testing
- Docker containers and Docker Compose setup
- Datadog or Sentry error monitoring
- Rate limiting with Redis
- Unit and integration tests (80%+ coverage)
- Deployment scripts for AWS, GCP, or Azure
- Runbook for incident response
What we ship in this practice.

Why teams hire us.
Senior engineers only, no juniors
Every API is built by a senior engineer with 8+ years of experience. We don't staff juniors or offshore teams. You get a lead architect who owns the project end to end.
Fixed price, not hourly billing
You get a fixed price after the Roadmap phase. No hourly billing, no time tracking, no surprises. If the scope changes, we agree on a new price before we start.
8-12 week delivery guarantee
We deliver your API in 8-12 weeks or we discount. 98% of our projects finish on time. We use 2-week sprints with demos every Monday.
Full code ownership
You own 100% of the source code, documentation, and infrastructure. No proprietary frameworks, no license fees. You can take the code to any team.
Compliance built in from day one
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the API design. No retrofitting. We use encryption, audit logging, and access controls by default.
Post-launch support included for 30 days
We stay on call for 30 days after launch. We fix bugs, answer questions, and help your team take over. No extra cost.
