Expert API Development ServicesDevelopment Services
We build secure, scalable APIs that move your data. Get a fixed-price MVP in 12 weeks with full code ownership.
IRPR builds expert API development services using Node.js, Python, Go, and Rust. We design REST, GraphQL, and gRPC APIs that handle 10,000+ requests per second with sub-100ms latency.
Every project ships a production-grade API in 12-14 weeks with fixed pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code and a CI/CD pipeline on day one.
We work with CTOs who need a scalable backend for their SaaS product, product managers integrating third-party data into their platform, and engineering leads who want to offload API development to a senior team without hiring overhead.
Types of software we ship.
REST API development
Build stateless RESTful APIs with Node.js or Python. Includes Swagger docs, rate limiting, and OAuth2 auth.
GraphQL API development
Design flexible GraphQL schemas with Apollo Server or Relay. Query optimization reduces over-fetching by 40%.
Microservices API architecture
Decompose monoliths into independent services with Docker, Kubernetes, and event-driven messaging via Kafka.
Third-party API integration

Real-time API with WebSockets
Build live data feeds for chat, notifications, or dashboards using Socket.IO or AWS API Gateway WebSockets.
Public API / Developer portal
Create a public-facing API with developer docs, API keys, usage analytics, and rate limiting using Kong or Tyk.
Internal API / B2B API
Secure internal APIs for enterprise systems with RBAC, audit logging, and integration with Active Directory.
AI / ML API endpoint
Wrap machine learning models in a REST or gRPC API. Supports TensorFlow, PyTorch, and ONNX with auto-scaling.
We build for every business type.
SaaS and platforms
eCommerce and retail
healthcare and fintech

Why expert API development services matter for your product
A well-designed API is the backbone of every modern application.
At IRPR, we have shipped over 200 APIs across 50 countries. Our senior engineers write code that handles 99.9% uptime and scales from 100 to 100,000 users without a rewrite. We use tools like Postman for testing, Sentry for error tracking, and Datadog for monitoring.
Every API we build includes automated tests (unit, integration, and load tests) that run in CI/CD. We deliver a complete Postman collection, Swagger/OpenAPI spec, and deployment scripts for AWS, GCP, or Azure. No handoff gaps.
The difference between generic dev shops and IRPR
Most agencies treat API development as a side project. We treat it as the core of your product.
Generic shops assign junior developers who learn on your dime. They rarely deliver on time, and the code is often unmaintainable. IRPR assigns senior engineers with 10+ years of experience who ship production-grade APIs on a fixed schedule.
We write clean, documented, tested code. Every API comes with a deployment playbook, monitoring dashboards, and a 30-day warranty. You own everything.
- Junior developers with 1-2 years of experience
- No API design review or architecture plan
- Hourly billing with no cap
- No automated tests or CI/CD
- No documentation or Postman collection
- Code ownership often unclear
- Senior engineers with 10+ years experience
- API design review and architecture doc in week 1
- Fixed price from $80K to $250K
- 100% test coverage and CI/CD on day one
- Full OpenAPI spec and Postman collection
- Complete code ownership, no licensing
How we deliver expert API development services in 12 weeks
Our process is designed for speed and quality. No wasted cycles.
We start with a 2-week Roadmap phase where we define the API contract, data models, and architecture. You get a detailed spec and a fixed price before any code is written.
Then we build in 2-week sprints. You see working endpoints every 14 days. We deploy to a staging environment so you can test immediately. Final release includes production deployment and a 30-day warranty.
What ships with every expert API development project
You get more than code. You get a complete system that runs in production.
We deliver a fully deployed, monitored, and documented API. No handoff gaps. No missing pieces. You can start using it the same day we finish.
All code is in your private GitHub repository. You own it from day one. No licensing fees, no vendor lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit, integration, and load tests
- OpenAPI/Swagger 3.0 specification
- Postman collection with example requests
- Deployment scripts for AWS/GCP/Azure
- Sentry error tracking and Datadog monitoring
- Rate limiting and API key management
- Security audit report (OWASP top 10)
- 30-day post-release support warranty
What we ship in this practice.
SaaS subscription management API

ML model inference API for edtech
Wrapped a recommendation model in a gRPC API for an edtech platform. Handles 500 requests/second with sub-50ms latency. Tech stack: Python, TensorFlow, gRPC, Kubernetes.
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. You know the cost before we write a line of code.
Senior engineers only
IRPR does not hire juniors. Every engineer has 10+ years of experience building production APIs. You get a lead architect who owns the design and a senior developer who writes the code.
Full code ownership
You own every line of code from day one. No licensing, no royalties, no vendor lock-in. We put everything in your GitHub repo and walk away.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant APIs. Our engineers know the audit requirements and bake them into the architecture from the start.
12-week delivery guarantee
We ship a production-ready API in 12 weeks or less. Our track record is 98% on-time delivery across 200+ projects. If we are late, we discount the next sprint.
Post-release support included
Every project includes 30 days of post-release support for bug fixes and minor changes. We do not disappear after launch. Extended maintenance available at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
