Professional API Development FirmAPI Development
We build production-grade APIs for startups and enterprises. 8-12 week delivery with senior engineers.
IRPR is a professional API development firm that builds RESTful and GraphQL APIs using Node.js, Go, Python, and PostgreSQL. Every API includes automated testing (Jest, Cypress), rate limiting, and Swagger documentation.
We deliver APIs in 8-12 weeks with fixed pricing from $80K to $250K. All projects comply with SOC 2, HIPAA, or PCI-DSS depending on your industry. Senior engineers with 8+ years experience handle every layer from auth to monitoring.
CTOs scaling SaaS platforms hire us to replace monolithic backends. Product managers launch MVPs with a clean API layer. Enterprise architects modernize legacy systems by extracting microservices. Startups ship core products on a predictable timeline.
Types of software we ship.
REST API Development
Stateless, resource-oriented APIs built with Express.js or FastAPI. Includes pagination, versioning, and OAuth2 authentication.
GraphQL API Development
Schema-first GraphQL APIs using Apollo Server and Prisma. Single endpoint, client-driven queries, real-time subscriptions.
Microservices API
Decoupled services communicating via gRPC or message queues (RabbitMQ, Kafka). Containerized with Docker and orchestrated on Kubernetes.
Third-Party API Integration
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any REST/SOAP API. Managed webhooks and OAuth flows included.
Real-Time API (WebSocket)
Low-latency WebSocket APIs for chat, notifications, and live dashboards. Built with Socket.io or AWS API Gateway WebSockets.
API Gateway Development
Centralized gateway with rate limiting, caching, and request transformation. Uses Kong, Apigee, or custom middleware on AWS API Gateway.
Payment API Integration
Secure payment APIs integrating with Stripe, Braintree, PayPal, or Adyen. Handles idempotency, refunds, and PCI-DSS compliance.
Data API (RESTful/JSON)
Read-optimized APIs serving large datasets with caching (Redis, CDN) and pagination. Ideal for mobile apps and frontend consumption.
We build for every business type.
Enterprise companies
SaaS platforms
Ecommerce
Fintech
Healthcare
Why choose a professional API development firm like IRPR
We have shipped over 200 APIs across 50+ countries with a 98% on-time delivery rate.
Every API we build is designed for scale from day one. Our senior engineers use automated CI/CD pipelines, Docker containers, and AWS/GCP infrastructure to ensure 99.9% uptime. We include monitoring with Datadog and error tracking with Sentry.
Our clients range from YC-backed startups to Fortune 500 companies. They choose us because we deliver on time, on budget, and with full code ownership. No black boxes, no long-term contracts, no hourly billing.
IRPR vs generic development shops
Most agencies claim to build APIs, but they cut corners on security, documentation, and reliability.
We have seen codebases with no tests, no rate limiting, and secrets hardcoded in environment files. Those APIs fail under load and expose sensitive data. IRPR follows strict standards from day one.
Every API we deliver includes automated integration tests, API contracts (OpenAPI 3.0), and secrets management via HashiCorp Vault or AWS Secrets Manager. We treat your API as a product, not a side project.
- No API versioning strategy
- Missing rate limiting and auth
- No documentation or Swagger
- Hardcoded secrets in config
- No monitoring or alerting
- Hourly billing with scope creep
- Semantic versioning (v1, v2)
- JWT + OAuth2 + rate limiting
- OpenAPI 3.0 docs auto-generated
- Secrets managed via Vault or AWS
- Datadog + Sentry monitoring
- Fixed price, no hidden fees
How we build your API in 8-12 weeks
Our process is transparent, fast, and designed to ship a production-ready API on a fixed timeline.
We start with a discovery week where we map your data model, endpoints, and integration points. Then we move to the Roadmap phase where we lock scope, architecture, and price.
The Build phase runs in 2-week sprints with daily standups and weekly demos. You see working endpoints every Monday. The Release phase includes load testing, security audit, and deployment to your cloud.
What ships with every API
You get more than just endpoints. Every delivery includes the complete infrastructure to run and maintain your API.
We don't throw code over the wall. You receive a production-ready API running on your AWS or GCP account, with monitoring, logging, and alerting pre-configured.
Your team can extend the API immediately because we include full documentation and a developer portal on ReadMe or Stoplight.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerized API containers
- OpenAPI 3.0 documentation
- Postman collection for testing
- Sentry error tracking
- Datadog monitoring dashboard
- Load test results (k6 report)
- Security audit report (OWASP)
- Deployment runbook
What we ship in this practice.
