Expert Custom API Development TeamAPI Development
We build secure, scalable APIs for your product. 200+ projects shipped in 12 weeks or less.
IRPR is an expert custom API development team that builds REST, GraphQL, and gRPC APIs for web and mobile products. We use Node.js, Python, Go, and Postgres to deliver APIs that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication, rate limiting, documentation, and compliance for HIPAA, PCI-DSS, and SOC 2.
CTOs hire us to build internal microservices. Product managers hire us to integrate third-party APIs like Stripe and Salesforce. Startup founders hire us to launch their SaaS MVP with a production-ready API.
Types of software we ship.
REST API development
Build stateless RESTful APIs with OpenAPI specs, JWT auth, and Postgres. Used for web and mobile backends.
GraphQL API development
Develop GraphQL APIs with Apollo Server, resolver patterns, and real-time subscriptions. Ideal for complex data queries.
gRPC API development
Create high-performance gRPC APIs with Protocol Buffers, streaming, and bidirectional communication. Used for microservices.
Third-party API integration
Integrate Stripe, Salesforce, HubSpot, Twilio, and 50+ other APIs. Handle webhooks, OAuth, and error retries.
Microservices API gateway
Design API gateways with Kong or Envoy. Route traffic, enforce rate limits, and aggregate responses from multiple services.
Internal API development
Build internal APIs for CRM, ERP, and HR systems. Connect legacy databases with modern REST endpoints.
Real-time API development
Develop WebSocket and Server-Sent Events APIs for live dashboards, chat, and notifications. Use Redis for pub/sub.

Why hire an expert custom API development team
A poorly designed API costs you time, money, and customers.
IRPR has shipped 200+ APIs for clients in 50 countries. Our APIs handle 10,000 requests per second with 99.9% uptime. We use Postgres, Redis, and cloud-native load balancers to keep latency under 50ms.
Every API comes with OpenAPI documentation, automated tests, and a CI/CD pipeline. We deploy to AWS, GCP, or Azure. You own the code and the infrastructure from day one.
Generic dev shop vs IRPR
Not all API teams deliver the same quality.
Generic shops reuse boilerplate code and skip security reviews. They deliver late and over budget. IRPR builds every API from scratch with your specific use case in mind.
We write unit tests, integration tests, and load tests. We document every endpoint with OpenAPI. We deploy with zero-downtime strategies.
- No API documentation
- No rate limiting
- No automated tests
- No CI/CD pipeline
- No security audit
- Hourly billing with scope creep
- OpenAPI 3.0 documentation
- Rate limiting and throttling
- 100% test coverage
- GitHub Actions CI/CD
- OWASP Top 10 audit
- Fixed price, no surprises
How we build your custom API
We follow a 4-phase process that guarantees delivery in 12 weeks.
Phase 1: Idea. We map your data model, endpoints, and auth strategy. You get a detailed API spec in week 1.
Phase 2: Roadmap. We estimate every endpoint, write user stories, and lock the price. You approve before we write code.
What ships with your API
Every API project includes these deliverables by default.
You get everything you need to maintain and scale your API. No hidden costs, no missing pieces.
IRPR hands over the full source code, infrastructure as code, and monitoring dashboards. Your team can take over immediately.
- Source code in your GitHub repo
- OpenAPI 3.0 documentation
- CI/CD pipeline on GitHub Actions
- Docker containers for local dev
- Postgres schema and migrations
- Redis caching layer
- Sentry error tracking
- Datadog monitoring dashboard
- Load test results (k6)
- 30-day post-launch support
What we ship in this practice.
SaaS product API
Built a REST API for a B2B SaaS platform handling 50,000 daily requests. Used Node.js, Postgres, and Redis. Reduced page load time by 60%.
Ecommerce order API
Developed a GraphQL API for an ecommerce brand to sync orders between Shopify and their warehouse. Integrated with Stripe and ShipStation. Cut manual data entry by 8 hours per week.
Healthcare patient API
Created a HIPAA-compliant REST API for a telehealth startup. Used Python, FastAPI, and AWS. Handled 10,000 patient records with end-to-end encryption.
Fintech payment API
Built a PCI-DSS compliant payment processing API for a lending platform. Integrated with Plaid and Stripe. Processed $2M in transactions in the first month.
Real estate MLS API
Developed a gRPC API to aggregate MLS listings from 5 different sources. Used Go and Postgres. Reduced listing sync time from 4 hours to 15 minutes.
Logistics tracking API
Built a real-time WebSocket API for a logistics company to track 500 delivery trucks. Used Node.js, Redis, and Google Maps API. Improved delivery ETA accuracy by 35%.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
IRPR hires only senior engineers with 8+ years of experience. No juniors, no offshore teams. Every API is built by someone who has shipped 10+ production APIs.
12-week delivery guarantee
We ship your API in 8-12 weeks or we extend at no cost. 98% of our projects finish on time. We use 2-week sprints with visible progress.
Full code ownership
You own the source code, the infrastructure, and the documentation from day one. No licensing fees, no vendor lock-in. Your team can take over anytime.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Encryption, audit logs, and access controls are part of every project.
Post-launch support included
Every API comes with 30 days of post-launch support. We fix bugs, answer questions, and help your team deploy updates. After that, we offer maintenance at $150/hour.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
