We design and build APIs that your developers will actually enjoy using. 200+ products shipped, 8-12 week timelines, fixed pricing.
IRPR is a team of senior API development consultants. We build REST APIs with Node.js and Express, GraphQL APIs with Apollo Server, and gRPC services with Go. Every API ships with OpenAPI 3.0 documentation and automated Postman collections.
A typical API project takes 8-12 weeks from kickoff to production. Fixed pricing starts at $80K for a single API service and goes up to $250K for a full microservices architecture. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
We work with CTOs who need to launch a SaaS product with a clean API layer. We work with product managers who need to integrate third-party services like Stripe, Salesforce, or Twilio. We work with engineering leads who want to migrate from a monolith to microservices without breaking production.
Build stateless REST APIs with Node.js, Express, and PostgreSQL. Includes JWT auth, rate limiting, and Swagger docs.
Design GraphQL schemas with Apollo Server and Prisma. Resolve N+1 queries with DataLoader and cache with Redis.
Build high-performance gRPC services with Protocol Buffers in Go or Node.js. Ideal for internal microservices communication.
Connect your app to Stripe, Salesforce, HubSpot, Twilio, or any third-party API. We handle OAuth, webhooks, and error retries.
Design a microservices architecture with API gateways, service discovery (Consul), and message queues (RabbitMQ or Kafka).
Implement OAuth 2.0, OpenID Connect, API key rotation, and rate limiting. We audit your existing APIs for OWASP Top 10 vulnerabilities.
Generate OpenAPI 3.0 specs, Postman collections, and automated integration tests with Supertest and Jest. Docs hosted on Stoplight.
Define your API-first strategy: versioning, deprecation policies, developer portal design, and monetization models like usage-based billing.
Building a production-grade API is harder than it looks. Here is what our clients typically gain.
A well-designed API reduces frontend development time by 30-40%. Our clients ship their web and mobile apps faster because the API is consistent, documented, and tested from day one. We use OpenAPI 3.0 to generate client SDKs automatically.
We have built APIs that handle 10,000 requests per second on a single instance. Our APIs use Redis caching, database connection pooling, and horizontal scaling with Kubernetes. Every API ships with a load testing report from k6.
Not all API consultants deliver the same quality. Here is the difference.
Generic dev shops often skip API documentation, use inconsistent error formats, and ignore rate limiting. Their APIs break under load and require constant maintenance. You end up with a black box that nobody wants to touch.
IRPR treats your API as a product. We write OpenAPI specs before writing code. We enforce consistent error responses (RFC 7807), add pagination by default, and include health check endpoints. Every API ships with a developer portal and automated tests.
We follow a four-phase process to deliver your API on time and on budget.
Every project starts with a 2-week Roadmap phase. We define the API contract, choose the tech stack, and estimate the fixed price. You get a detailed specification before any code is written.
After the Roadmap, we build the API in 6-10 weeks. We ship incrementally every 2 weeks with a working endpoint. You can test and provide feedback throughout the build.
Every API project includes these deliverables by default. No hidden extras.
We believe in shipping a complete product, not just code. Every API comes with documentation, tests, monitoring, and a deployment pipeline. Your team can take over immediately.
All source code is in your GitHub repository from day one. We use GitHub Actions for CI/CD, Docker for containerization, and Terraform for infrastructure. You own everything.
Built a REST API that processes 5,000 transactions per day with Stripe Connect. Reduced payment failure rate from 8% to 2% with automatic retries and idempotency keys. Tech stack: Node.js, Express, PostgreSQL, Stripe API, Redis.
Designed a FHIR-compliant API for patient records, appointments, and prescriptions. Achieved HIPAA compliance with end-to-end encryption and audit logging. Tech stack: Go, gRPC, PostgreSQL, AWS KMS, FHIR R4.
Built a GraphQL API that serves 50,000 products with faceted search and real-time inventory. Reduced page load time from 3 seconds to 400ms with DataLoader and Redis caching. Tech stack: Apollo Server, Prisma, PostgreSQL, Redis, Next.js.
Created a unified API that syncs contacts, deals, and activities between HubSpot and Salesforce. Eliminated manual data entry for 200 sales reps, saving 10 hours per week. Tech stack: Node.js, Express, HubSpot API, Salesforce REST API, Bull queue.
Developed a REST API that aggregates MLS data from 50+ sources into a single search endpoint. Reduced data latency from 24 hours to 15 minutes with webhook-based updates. Tech stack: Python, FastAPI, PostgreSQL, Redis, AWS Lambda.
Built a FERPA-compliant API for student registration, grade submission, and parent communication. Handled 10,000 concurrent users during enrollment periods with zero downtime. Tech stack: Node.js, Express, MongoDB, Redis, AWS ECS.
Every API project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Every API development consultant at IRPR has 10+ years of experience. No junior developers, no offshore teams, no handoffs. The person you talk to on the discovery call is the person building your API.
We write the OpenAPI 3.0 spec before writing any code. Your frontend team can start building against the spec immediately. No waiting for endpoints to be ready.
Every API ships with monitoring, alerting, rate limiting, and automated deployments. We use Sentry for error tracking and Datadog for performance dashboards. Your API is ready for production traffic.
You own all source code, documentation, and infrastructure configs from day one. No proprietary frameworks, no locked-in tools. Your team can take over and extend the API immediately.
We build APIs that meet HIPAA, PCI-DSS, SOC 2, and FERPA requirements. We handle encryption, audit logging, access controls, and data retention policies. Your compliance audit will pass.
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.
