Custom REST API Development Partner for Scalable BackendsREST API
We build RESTful APIs that power your apps. Launch in 8-12 weeks with a fixed price.
IRPR builds REST APIs for web and mobile applications using Node.js, Python (FastAPI), Go, or Java Spring Boot. We design APIs that are secure, documented, and ready for scale.
Our typical API project ships in 12 weeks with prices starting at $80K and ranging up to $250K. We handle compliance like HIPAA, PCI-DSS, and SOC 2 out of the box.
Companies hire us as their REST API development partner when they need a reliable backend: CTOs scaling their platform, founders launching a new product, product managers integrating third-party services, and data teams building data pipelines.
Types of software we ship.
RESTful API for Mobile Apps
Build a REST API consumed by iOS and Android using Firebase Auth and Cloud Functions for push notifications and user management.
Public API for Third-Party Integrations
Expose a public REST API with API keys, rate limiting, and developer docs using Express and Swagger UI.
Internal Microservices API for SaaS
Design microservices with Go and gRPC for low-latency communication between internal services and databases.
API Gateway with Rate Limiting

We build for every business type.
Ecommerce
SaaS
Healthcare

Why your API needs a dedicated development partner
A production-grade REST API requires more than a weekend tutorial.
Without a structured approach, APIs end up with inconsistent endpoints, missing error handling, and no documentation. That leads to broken integrations and slow debugging for your frontend and mobile teams.
IRPR treats your API like a product. We write an OpenAPI 3.1 specification before any code, build automated tests, and deploy with CI/CD. Every API we ship includes rate limiting, caching, and monitoring from day one.
Generic dev shop vs IRPR
The difference between a one-time contractor and a true engineering partner.
Most dev shops promise an API but deliver a pile of code with no documentation, no tests, and no ownership plan. You end up debugging their work for weeks after launch.
IRPR builds APIs the right way. Every project includes a spec, tests, CI/CD, monitoring, and full code ownership. You can hand it to any engineer on day one.
- No API design standards or versioning
- Missing documentation or outdated docs
- No rate limiting or caching strategy
- Unclear pricing with hidden hourly fees
- No post-launch support or monitoring
- Code ownership is ambiguous
- OpenAPI 3.1 specification from day one
- Automated API docs with Swagger UI
- Built-in rate limiting, caching, and monitoring
- Fixed price with Roadmap phase (week 2)
- 98% on-time delivery and 12-week average
- Full code ownership with CI/CD pipeline
How we build your REST API
A repeatable process that delivers a production-ready API in weeks, not months.
We start with a 2-week Roadmap phase to define every endpoint, data model, and integration point. You get an OpenAPI spec, a migration plan, and a fixed price before any code is written.
Then we build in 2-week sprints with automated testing and continuous deployment. You see a deployed API endpoint every sprint and can test it with your frontend team.
What ships with every API project
Everything you need to run, maintain, and scale your REST API from day one.
We don't hand over a zip file and walk away. Every project includes a complete delivery package that your team can use immediately.
Your engineers get the same setup our senior engineers use: automated builds, error tracking, and deployment scripts.
- Source code in your private GitHub repo
- OpenAPI 3.1 specification
- Automated tests (unit, integration, e2e)
- CI/CD pipeline on GitHub Actions
- Docker containerization with Dockerfiles
- Sentry error tracking and performance monitoring
- Cloud deployment script (AWS, GCP, or Azure)
- Postman collection for manual testing
- Admin dashboard or CLI for API management
- Slack notifications on deployment and errors
What we ship in this practice.
Payment Processing API for a Fintech Startup
Built with Node.js, PostgreSQL, and Stripe SDK. This API processed 10,000 transactions in the first month and reduced payment failures by 40% through automatic retries and idempotency keys.
Patient Data API for a Telemedicine App
Built with Python FastAPI and HIPAA-compliant data storage. The API enabled real-time patient-provider messaging and reduced manual data entry by 8 hours per week per clinician.
Inventory Sync API for an Ecommerce Platform
Built with Go and PostgreSQL. This API synced inventory across 3 warehouses and 2 marketplaces (Amazon, eBay) in under 500ms, eliminating overselling and saving the client $20K per quarter in penalties.
Real-Time Tracking API for a Logistics SaaS
Built with Node.js, WebSockets, and Redis. The API provided real-time GPS tracking for 500+ vehicles, cutting customer support inquiries by 30%.
Analytics API for a Marketing Dashboard
Built with Python FastAPI and ClickHouse. This API processed 2 million events per day and returned aggregated reports in under 2 seconds, replacing a legacy system that took 15 seconds.
Content API for a Media Subscription Service
Built with Node.js, MongoDB, and AWS CloudFront. The API served 1 million requests per day with 99.9% uptime and enabled dynamic content personalization based on user behavior.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
OpenAPI spec from day one
We write an OpenAPI 3.1 specification before any code is written. Your frontend and mobile teams can start building against mock endpoints immediately.
Production-grade security defaults
Every API includes authentication (JWT, OAuth2), rate limiting, input validation, and encryption at rest and in transit. We follow HIPAA, PCI-DSS, and SOC 2 guidelines.
Ships with full test coverage
We write unit, integration, and end-to-end tests for every endpoint. Our CI pipeline runs them on every commit. Test coverage is reported in every sprint review.
We own the timeline, you own the code
We deliver on time 98% of the time. When the project ends, you get full source code, documentation, and CI/CD pipeline. No licenses, no recurring fees.
Post-launch support included
Every project includes 30 days of post-launch support. We monitor errors, fix bugs, and help your team take over the codebase. Extended support is available at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
