Premium REST API Development DevelopersREST API
We build production-ready REST APIs for your product in 12 weeks or less. Our senior engineers handle everything from spec to deployment.
IRPR builds premium REST APIs using Node.js, Python, Ruby on Rails, and Go. We design every endpoint with OpenAPI 3.0 specs so your documentation is always accurate and testable.
A typical project ships in 8-12 weeks with a fixed price between $80,000 and $250,000. Every API is built for compliance: HIPAA, PCI-DSS, SOC 2, or FERPA depending on your industry.
We work with CTOs who need a custom integration layer, product managers scaling an MVP, startup founders replacing a brittle legacy API, and enterprise architects consolidating microservices.
Types of software we ship.
Third-party API Integration Layer

Why premium REST API development matters
A well-built API is the backbone of every modern product and integration.
IRPR has delivered 200+ APIs for products in healthcare, fintech, ecommerce, and SaaS. Every API is designed for throughput, security, and developer experience from day one.
Our engineers use OpenAPI specs, automated testing, and continuous integration to ship reliable code. We have maintained 99.9% uptime across all production APIs for the last three years.
How IRPR is different from generic dev shops
Most agencies bill hourly and deliver late. IRPR does the opposite.
Generic dev shops often assign junior developers to API projects, leading to inconsistent documentation, weak security, and hidden costs. They charge by the hour and rarely guarantee timelines.
IRPR assigns senior engineers only — each with 10+ years of experience. We give you a fixed price after a 2-week Roadmap phase and guarantee delivery within 12 weeks. Full code ownership is yours from day one.
- Junior or mixed-skill teams
- Hourly billing with unlimited scope creep
- No timeline guarantee
- Vague documentation or none
- No compliance certifications
- Code stays with them unless you buy out
- Senior engineers only (10+ yr avg.)
- Fixed price quoted in week 2
- 12-week delivery guarantee
- OpenAPI 3.0 docs included
- HIPAA, PCI, SOC 2 ready
- Full code ownership from start
Our REST API development process
Four phases from idea to production, each with a concrete deliverable.
Every project begins with a 1-2 week Discovery where we define endpoints, data models, and auth flows. No code yet — just specs and mockups.
After your approval, we move to a 6-10 week Development sprint with continuous delivery. You see working endpoints every two weeks.
What ships when we build your REST API
Every deliverable is written, tested, and ready for production.
We do not just hand you code files. Every project comes with infrastructure, documentation, and monitoring already configured. You can start integrating within hours of deployment.
- Source code in your private repository (GitHub, GitLab, or Bitbucket)
- CI/CD pipeline with automated tests (GitHub Actions or CircleCI)
- OpenAPI 3.0 specification for every endpoint
- Deployment scripts for AWS, GCP, or Azure
- Performance load test results (k6 or Locust)
- Error tracking with Sentry
- Application performance monitoring with Datadog
- Security audit report (OWASP Top 10 checks)
- Dev, staging, and production environment configs
- Postman collection for manual testing
What we ship in this practice.

Order Management API for Ecommerce Brand
Processed 10,000 orders daily via a custom REST API integrated with Shopify and a warehouse WMS. Reduced order processing time by 60%. Stack: Node.js, MongoDB, and AWS Lambda.
Social Graph API for Social Media App
Scaled to 1 million users with a hybrid REST/GraphQL API for feeds, friendships, and notifications. Used Go for performance-critical endpoints and PostgreSQL for persistence.
Inventory Sync API for Logistics Platform
Provided real-time inventory synchronization across 30 warehouses using REST webhooks and Kafka. Reduced stockouts by 30% and saved $200K in lost sales. Stack: Go, Kafka, and TimescaleDB.
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. You know the total cost before we write a line of code.
Senior engineers only
Our teams have an average of 10+ years of software engineering experience. No juniors, no offshore ratios. Every developer has shipped production APIs for at least five clients.
Full code ownership
From day one, all code is stored in your company’s repository. We never hold your intellectual property hostage. You can take the code to any other team after the project ends.
12-week delivery guarantee
We guarantee delivery within 12 weeks for any project within the scoped budget. If we are late, we cover the cost of extra weeks. This has happened exactly once in 200+ projects.
Built-in compliance
Every API is built with compliance requirements in mind. We have delivered HIPAA, PCI-DSS, SOC 2, and FERPA compliant projects. Our engineers know the audit trail and encryption standards.
Post-launch support included
After deployment, you get 30 days of free support for bug fixes, tweaks, and integration questions. We also provide a 90-day optional extended support contract at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
