We build secure, scalable APIs for your product. REST, GraphQL, and microservices in 8-12 weeks.
IRPR is a top custom API development studio that builds production-grade APIs for web and mobile apps. We use Node.js, Python, Go, and Rust with frameworks like Express, FastAPI, and GraphQL Yoga.
Every custom API ships in 8-12 weeks with fixed pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2, and include full CI/CD pipeline, monitoring with Datadog, and auto-generated OpenAPI documentation.
Our clients include startup CTOs who need a scalable backend for their MVP, product managers integrating third-party services like Stripe or Salesforce, and enterprise architects migrating monolithic systems to microservices.
Build stateless RESTful APIs with JSON responses using Express or Fastify. Ideal for web and mobile clients.
Create flexible GraphQL endpoints with Apollo Server or Yoga. Clients query exactly the data they need.
Design and build decoupled microservices with gRPC and message queues like RabbitMQ or NATS.
Integrate with Stripe, Salesforce, HubSpot, or Twilio using custom connectors and webhook handlers.
Audit your API against OWASP Top 10 vulnerabilities. Implement rate limiting, authentication, and encryption.
Auto-generate interactive API docs with Swagger UI or Redoc from OpenAPI 3.0 specifications.
Implement token bucket or sliding window rate limits using Redis and middleware like express-rate-limit.
Manage API versions with URI or header strategies using tools like Kong or Tyk for seamless upgrades.
Off-the-shelf APIs don't fit your exact business logic or performance requirements.
A custom API gives you full control over data models, authentication, and scalability. IRPR has built over 200 APIs for clients in 50+ countries, each designed to handle production traffic from day one.
We use a structured Roadmap phase to define endpoints, error handling, and caching strategies before writing a single line of code. This eliminates rework and keeps timelines predictable.
Many API projects fail because of vague requirements and poor architecture decisions.
A generic development shop often skips API design standards and security reviews. The result is an API that breaks under load or leaks data.
IRPR treats each API as a product. We write OpenAPI specs, include unit tests, and set up monitoring before launch. This is why 98% of our projects deliver on time.
We follow a structured 4-phase process to ship your custom API on time and on budget.
Every project starts with a 2-week Roadmap phase where we define endpoints, data models, and security controls. You get a fixed price and timeline.
Then we build iteratively, delivering a working API every 2 weeks. The last phase includes load testing, documentation, and production deployment.
Every IRPR API project includes these items by default. No hidden costs or add-ons.
We believe in full transparency. From source code to monitoring, everything you need to run your API in production is included in the fixed price.
You get the complete project in your private GitHub repo, ready for your team to extend or maintain.
Built a gRPC-based payment API that reduced transaction latency by 40% compared to the previous REST endpoint. Handles 5,000 requests per second with 99.99% uptime. Tech stack: Go, gRPC, PostgreSQL, Stripe API.
Developed a HIPAA-compliant GraphQL API serving 10,000 daily patient records to mobile apps. Reduced data retrieval time by 60% using Redis caching. Tech stack: Node.js, Apollo Server, PostgreSQL, Redis.
Created a FastAPI service that syncs inventory between Shopify and Amazon every 5 minutes. Automates 20 hours of manual work per week. Tech stack: Python FastAPI, Celery, MySQL, Shopify Admin API.
Built a GraphQL API that aggregates MLS data across 10 sources, serving 500,000 property records with sub-second query response. Tech stack: GraphQL Yoga, Elasticsearch, AWS Lambda, RDS.
Delivered a REST API that supports 50,000 concurrent students during peak exam periods. Uses Redis for session caching and Celery for async notifications. Tech stack: Django REST, Celery, Redis, PostgreSQL.
Developed a FastAPI endpoint that reduces tracking query time by 60% using Redis caching and optimized SQL queries. Handles 1 million tracking requests daily. Tech stack: Python FastAPI, Redis, PostgreSQL, AWS API Gateway.
Every engineer on your project has 8+ years of experience building production APIs. We never outsource or assign junior developers to client projects.
You get a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Most custom APIs ship within 12 weeks. Our fastest project was a lightweight REST API delivered in 6 weeks.
You own all source code from day one. No licensing fees, no vendor lock-in. The code is yours to deploy anywhere.
We audit API security against OWASP Top 10 in the Roadmap phase. HIPAA, PCI-DSS, and SOC 2 controls are coded from week 1.
We include 30 days of production support after launch. Sentry and Datadog monitoring remain active during this period.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
