Professional REST API Development StudioREST API Development
We build production-grade REST APIs in 12 weeks. Fixed price, no surprises.
IRPR is a professional REST API development studio that builds production APIs using Node.js (Express, Fastify), Python (FastAPI, Django REST), Go (Gin), and Java (Spring Boot). We design endpoints, handle auth (OAuth2, JWT), and document with OpenAPI 3.0.
Every project ships in 12-14 weeks with a fixed price of $80K-$250K. We handle deployment on AWS (ECS, Lambda), Cloudflare, or GCP. All APIs pass security audits for HIPAA, PCI-DSS, or SOC 2 compliance.
Companies hire IRPR when they need a CTO-level API architect to replace a broken legacy API, when they need compliance-ready endpoints for healthcare or fintech, and when they want a scalable backend to support a mobile app launch.

Why hire a professional REST API development studio for your next platform?
A poorly designed API leads to broken integrations, slow frontends, and endless maintenance tickets.
At IRPR, we write every endpoint with proper error handling, idempotency, and pagination. Our APIs use OpenAPI 3.0 specs auto-generated from code. You get Swagger docs, Postman collections, and integration tests with 95% coverage.
We also ship with monitoring using Datadog APM and error tracking via Sentry. Every endpoint logs request/response payloads. Alerts fire at the 500ms threshold. Your team sees API health in real time.
How IRPR compares with generic dev shops for REST API development
Many shops say they build APIs, but few deliver secure, documented, and scalable endpoints on a fixed budget.
Generic shops often start with hourly billing, skip documentation, and deliver endpoints that fail under load. They rarely handle compliance or provide unit tests.
IRPR treats your API as a product. We design the schema in week 1, get your sign-off on the OpenAPI spec, and only then write code. You see working endpoints in week 4. Full delivery in week 12.
- Hourly billing with no fixed estimate
- No API documentation or spec
- No load testing before launch
- No compliance or security audit
- You own no code after delivery
- Slow response to bugs post-launch
- Fixed price from $80K to $250K
- OpenAPI 3.0 spec generated from code
- Load tested with k6 at 10K requests/min
- HIPAA, PCI-DSS, or SOC 2 compliant by default
- Full source code in your GitHub repo
- 2-week post-launch support included
Our proven 4-phase approach for REST API projects
Every API project follows the same roadmap from idea to release.
We start with a 2-week Roadmap phase where we define endpoints, data models, and auth flows. You get a fixed price quote and a timeline before any code is written.
In the Product phase, our senior engineers build the API in 8-10 weeks. You see progress on a preview endpoint every Friday. We run load tests and security scans before launch.
What ships with every REST API project from IRPR
You get more than just endpoints. Every delivery includes the full production setup.
Every project ships with CI/CD pipelines on GitHub Actions, automated tests with Jest or Pytest, and a staging environment on AWS ECS. We also include API documentation on SwaggerHub and a Postman collection.
Your team can deploy new versions with one pull request. We never lock you into our infrastructure. You own everything from day one.
- Source code in your GitHub repo
- OpenAPI 3.0 spec with Swagger UI
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Dockerized services for local development
- Load test results with k6 report
- Sentry error tracking configured
- Datadog APM monitoring dashboard
- Staging environment on AWS ECS
- 2-week post-launch support
What we ship in this practice.
Patient portal API for a telehealth startup
Built a HIPAA-compliant REST API for patient registration, appointment booking, and video call initiation. Reduced manual scheduling by 12 hours per week. Stack: FastAPI, PostgreSQL, Twilio, AWS ECS.

Property listing API for a real estate platform
Developed a REST API that ingests MLS data, geocodes addresses, and serves search results with 500ms response times. Integrated with 12 MLS providers. Stack: Python, FastAPI, ElasticSearch, Redis, AWS RDS.
Student enrollment API for an edtech platform
Designed a FERPA-compliant REST API for course registration, grade submission, and fee payments. Reduced enrollment processing time from 3 days to 2 hours. Stack: Django REST, PostgreSQL, Twilio, AWS S3.
Why teams hire us.
Fixed price, not hourly
Every 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 single line of code.
Senior engineers only
Every engineer on your project has 8+ years of backend experience. We do not outsource work. You talk directly with the engineers building your API, no account managers.
OpenAPI spec before code
Before writing a line of code, we produce a complete OpenAPI 3.0 spec. You review and approve every endpoint and data model. This eliminates rework and miscommunication.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, or SOC 2 compliance into the API from day one. Every endpoint logs audit trails, encrypts PHI data at rest and in transit, and handles PII according to GDPR.
Full source code ownership
You own every file. We deliver the code in your GitHub repo with no license restrictions. You can hire any team to maintain it after we finish.
2-week post-launch support
After the API goes live, we stay on for 2 weeks to fix bugs, handle edge cases, and help your frontend team integrate. No extra cost.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
