Best API Development TeamDevelopment Team
We build production-grade APIs that serve millions of requests per day. Fixed price, 8-12 week delivery, full ownership.
IRPR is the best API development team for companies that need reliable, scalable APIs. We build REST, GraphQL, and gRPC endpoints using Node.js, Python, Go, and PostgreSQL. Every API ships with automated tests, rate limiting, and monitoring.
We deliver a production-ready API in 8-12 weeks. Pricing starts at $80K and goes to $250K depending on complexity. All APIs meet HIPAA, PCI-DSS, and SOC 2 compliance standards. You get full ownership of the code and infrastructure.
Startups hire us to build their first public API. Mid-market companies hire us to replace brittle legacy integrations. Enterprise teams hire us to add PCI-compliant payment APIs or HIPAA-compliant patient data APIs.
Types of software we ship.

Why IRPR is the best API development team for your project
We have shipped over 200 APIs for clients in 50+ countries. Here is what that experience means for your project.
Every API we build starts with a clear contract: OpenAPI 3.0 or GraphQL SDL. You get a documented spec before any code is written. This eliminates guesswork and ensures both sides agree on endpoints, request formats, and response structures.
We deploy every API with automated CI/CD pipelines on GitHub Actions. Each push runs unit tests, integration tests, and security scans. Our APIs average 99.9% uptime with p99 latency under 200ms.
What sets the best API development team apart
Most API projects fail because of unclear specs, scope creep, or poor testing. Here is how we avoid those problems.
Generic dev shops start coding from a vague requirements doc. They skip API contracts, skip load testing, and hand you code that breaks under traffic. You pay more for fixes later.
IRPR writes the API spec first. You approve it. We build to that spec. Every endpoint has a test. Every deployment is automated. You get a working API in 8-12 weeks, not 6 months.

- You own nothing until final payment
- OpenAPI 3.0 or GraphQL SDL spec before coding
- Fixed price from the Roadmap phase
- Load test with k6, security scan with OWASP ZAP
- CI/CD on GitHub Actions with automated deploys
- Auto-generated docs with Swagger UI
- Full code ownership from day one
Our API development process in 4 phases
We follow a structured process that takes your idea to a production API in 8-12 weeks.
Phase 1 is the Roadmap. In week 2, we deliver a detailed spec, architecture diagram, and fixed price quote. You approve the plan before we write a single line of code.
Phases 2-4 are build, test, and release. We work in 2-week sprints with demo at the end of each sprint. You see progress every step of the way.
What ships with every API project
You get more than just code. Every API project includes these deliverables by default.
We believe in shipping a complete product. That means source code, infrastructure, documentation, and monitoring all included in the fixed price.
- Source code in your GitHub repo
- OpenAPI 3.0 or GraphQL SDL specification
- CI/CD pipeline on GitHub Actions
- Automated unit and integration tests
- Load test report from k6
- Deployed to AWS or GCP with Terraform
- Sentry error tracking and Datadog monitoring
- Swagger UI or GraphQL Playground documentation
- Rate limiting and auth (JWT, OAuth2, API keys)
- Postman collection for manual testing
What we ship in this practice.
Payment API for a fintech startup
Built a PCI-DSS compliant payment API using Stripe Connect and Node.js. Handles 50,000 transactions per day with 99.99% uptime. Reduced payment processing errors by 80%.
FHIR API for a telehealth platform
Developed a HIPAA-compliant FHIR API using HAPI FHIR and PostgreSQL. Integrated with Epic EHR. Reduced patient data retrieval time from 3 minutes to 8 seconds.
Order management API for an ecommerce brand
Built a REST API with Node.js and Redis that syncs orders between Shopify and a custom warehouse system. Processes 10,000 orders per hour with zero data loss.
Analytics API for a SaaS platform
Created a GraphQL API with Apollo Server and ClickHouse. Serves real-time dashboards for 500+ users. Reduced page load time from 12 seconds to 1.5 seconds.
Real-time tracking API for a logistics company
Built a WebSocket API in Go that streams GPS data from 1,000+ trucks. Updated location every 5 seconds. Reduced delivery delays by 25%.
Content API for a media platform
Developed a REST API with FastAPI and Elasticsearch. Serves 2 million content requests per day. Reduced search latency from 800ms to 150ms.
Why teams hire us.
Fixed price from the Roadmap
Every API project gets a fixed price quote in week 2. No hourly billing, no surprise invoices. You know the cost before we write code.
API spec before code
We write the OpenAPI 3.0 or GraphQL SDL spec first. You review and approve it. No ambiguity about what the API will do.
Full ownership from day one
You own the source code, infrastructure, and documentation from the first commit. No licensing fees, no vendor lock-in.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Our healthcare APIs use BAA-covered infrastructure. Our fintech APIs use tokenization and encryption.
On-time delivery guarantee
98% of our API projects ship on time. We use 2-week sprints with demos. If we slip, you see it early and we adjust the scope together.
Senior engineers only
Every API is built by a senior engineer with 8+ years of experience. No junior devs. No offshore outsourcing. You talk directly to the person writing your code.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
