Why you need a professional REST API development company
REST APIs are the backbone of modern software. IRPR delivers them on time, on budget, and with full compliance.
A poorly designed REST API leads to technical debt, slow integrations, and security risks. IRPR's senior engineers design APIs with versioning, error handling, and pagination from day one. We use Postman and Swagger for testing and documentation.
We have shipped over 200 products across 50 countries. Our APIs handle millions of requests per day. Every project includes rate limiting, authentication, and monitoring with Datadog or New Relic.
Generic dev shop vs. IRPR
Not all API development companies are equal. Here is how IRPR stands apart.
Generic dev shops often start coding before defining the API contract. They skip documentation and fail to plan for scaling. This leads to messy APIs that break with every change.
IRPR follows a structured process. We first define the API contract using OpenAPI 3.0, then build endpoints, tests, and documentation in parallel. Every API is deployed with CI/CD and monitored from day one.
- No API contract before coding
- Mixed team skill levels
- Hourly billing with scope creep
- No security compliance built-in
- Documentation as an afterthought
- No monitoring or alerting
- OpenAPI contract defined in week 2
- Senior engineers only - 10+ years average
- Fixed price, no surprises
- HIPAA, PCI-DSS, SOC 2 compliance included
- Swagger/OpenAPI docs generated automatically
- Datadog monitoring and PagerDuty alerts
Our REST API development process
We follow a four-phase process to deliver your API in 8-12 weeks.
Each phase ends with a milestone and client sign-off. We use agile sprints with bi-weekly demos. Here are the steps we take.
What ships with every API
Every REST API project includes these deliverables by default.
No hidden extras. Everything here is part of the fixed price.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- OpenAPI 3.0 specification (Swagger UI)
- Postman collection with example requests
- Authentication (JWT or OAuth 2.0)
- Rate limiting and request validation
- Database migrations and seed scripts
- Unit tests with 90%+ coverage
- Datadog or New Relic monitoring configuration
- Deployment scripts for AWS ECS or EKS
What we ship in this practice.
Payment processing API for a fintech startup
IRPR built a REST API for a fintech startup handling ACH and credit card payments. The API processed 500,000 transactions in the first month. Tech stack: Node.js, PostgreSQL, Stripe, Plaid.
Patient portal API for a telehealth platform
We developed a HIPAA-compliant REST API for a telehealth company. The API allowed 50 clinics to schedule appointments and share medical records. Tech stack: Python, FastAPI, PostgreSQL, AWS Lambda.
Order management API for an ecommerce brand
IRPR built a REST API that unified orders across 3 sales channels (Shopify, Amazon, Magento). The client reduced manual order processing by 12 hours per week. Tech stack: Go, MongoDB, RabbitMQ, Stripe.
Subscription billing API for a SaaS company
We built a REST API to manage plans, usage metering, and invoices. The SaaS company scaled from 200 to 5,000 customers in 6 months. Tech stack: Node.js, PostgreSQL, Stripe, Redis.
Property search API for a real estate platform
IRPR created a REST API that aggregates MLS listings from 5 regional boards. The API returns search results in under 200ms. Tech stack: Python, Django, Elasticsearch, AWS RDS.
Learning management API for an edtech startup
We built a FERPA-compliant REST API for a learning management platform serving 120 schools. The API handles 2 million requests per day. Tech stack: Node.js, GraphQL (REST wrapper), Postgres, Redis.
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. You know the total cost before we write production code.
Senior engineers only
IRPR only hires senior engineers with 10+ years of experience. Our team includes API architects who have built systems for Twilio, Stripe, and Slack. No junior developers work on your project.
Full code ownership
You own the entire source code from day one. We commit everything to your GitHub repository. No licensing fees, no vendor lock-in, no black boxes.
CI/CD included by default
Every project ships with a production-grade CI/CD pipeline. We use GitHub Actions or GitLab CI for automated testing, linting, and deployment. Your API is deployable immediately.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Our engineers include encryption at rest, audit logs, and access controls from the start. No costly retrofitting later.
API documentation that ships
Every API includes interactive Swagger UI and Postman collections. Documentation is auto-generated from the OpenAPI spec and stays in sync with the codebase.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
