Experienced API Development StudioAPI Development
We build APIs that move data fast and stay secure. 200+ products shipped with REST, GraphQL, and gRPC.
IRPR is an experienced API development studio that designs and builds production-grade APIs using REST, GraphQL, and gRPC. We use Node.js, Go, Python, and Postgres to create APIs that handle millions of requests per day.
Every project ships with a documented API, automated tests, and a CI/CD pipeline. Typical timelines are 8-12 weeks for an MVP, with fixed pricing from $80K to $250K. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA standards.
We work with CTOs who need a secure API for their SaaS platform, product managers integrating third-party services, and founders launching a data-heavy MVP. Each client gets a senior engineer as the lead architect.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with JSON responses, rate limiting, and OAuth2 authentication using Express.js or FastAPI.
GraphQL API Development
Develop GraphQL APIs with Apollo Server or Hasura, enabling flexible queries and real-time subscriptions for modern frontends.
gRPC API Development
Implement high-performance gRPC services with Protocol Buffers, ideal for microservices communication and low-latency systems.
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, or Twilio with custom integration layers that handle auth, retries, and webhooks.
API Gateway Development
Design API gateways using Kong or AWS API Gateway to centralize routing, authentication, throttling, and logging for multiple services.
Webhook API Development
Build event-driven webhook systems that push data to external services in real time, with delivery guarantees and retry logic.
Internal API Development
Create internal APIs for microservices communication, using message queues like RabbitMQ or Kafka for async data flow.
Public API Development
Launch a public API product with developer portals, API keys, usage analytics, and documentation generated from OpenAPI specs.
We build for every business type.
SaaS platforms
fintech companies
healthcare providers
ecommerce brands
logistics and manufacturing
Why Choose an Experienced API Development Studio
A poorly designed API costs time, money, and trust. Here is what we deliver.
IRPR has shipped over 200 APIs across 50 countries. Every API is built with OpenAPI 3.0 documentation, automated testing with Postman or Jest, and a CI/CD pipeline using GitHub Actions. We enforce rate limiting, authentication via OAuth2 or JWT, and encryption at rest and in transit.
Our APIs are designed for scale. We use caching layers like Redis, load balancing with NGINX, and database indexing on Postgres. We have maintained 99.9% uptime across all production APIs for the last 3 years.
The Difference Between a Generic Dev Shop and an Experienced API Studio
Most dev shops treat APIs as an afterthought. IRPR builds them as the core product.
Generic shops often skip documentation, leave endpoints unsecured, and ignore error handling. They use one-size-fits-all frameworks without considering your data model or traffic patterns.
IRPR assigns a senior API architect to every project. We write OpenAPI specs before writing code. We include rate limiting, idempotency keys, and structured error responses. Every API ships with a developer portal and usage analytics.
- No API documentation or outdated docs
- No rate limiting or throttling
- No automated tests for endpoints
- No CI/CD pipeline for API deployments
- No monitoring or alerting
- No security audit or compliance checks
- OpenAPI 3.0 spec written before code
- Rate limiting with configurable tiers
- Automated integration tests with Jest
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and Datadog monitoring
- HIPAA, PCI-DSS, SOC 2 compliance built in
How We Build Your API in 4 Phases
Our process is designed to ship a production-ready API in 8-12 weeks.
Phase 1 is the Roadmap. We define the API endpoints, data model, auth strategy, and compliance requirements. You get a fixed price and timeline at the end of week 2.
Phase 2 is the build. Our senior engineers write the API code, tests, and documentation. Phase 3 is the release, where we deploy to staging, run load tests, and migrate data. Phase 4 is the handoff with full source code and runbooks.
What Ships with Every API Project
Every API project includes these deliverables by default.
We do not hand over a black box. You get everything needed to run, monitor, and extend the API yourself. Our team also provides 30 days of post-launch support.
All code is stored in your private GitHub repo. You own the IP. We do not license or resell your API.
- Source code in your private GitHub repo

- CI/CD pipeline on GitHub Actions
- Unit and integration tests (80%+ coverage)
- Sentry error tracking configured
- Datadog monitoring dashboard
- Rate limiting and authentication middleware
- Deployment runbook and on-call guide
- 30 days of post-launch support
What we ship in this practice.
Payment Processing API for Fintech Startup

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
We do not outsource or use junior devs. Every API is built by a senior engineer with 8+ years of experience. Our lead architects have shipped APIs for companies like Stripe and Twilio.
8-12 week MVPs
We ship a production-ready API in 8-12 weeks. That includes documentation, tests, CI/CD, and monitoring. We have delivered over 200 projects on time.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into every API from day one. We use encryption, audit logging, and access controls to pass audits.
Full code ownership
You own 100% of the source code. We do not license, resell, or reuse your API. All code goes into your private GitHub repo.
Global team, local hours
Our team spans 50+ countries but overlaps with US and EU time zones. You get daily standups and a dedicated project manager. No async-only communication.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
