Rest API Development DevelopersDevelopers
We build REST APIs that scale to millions of requests. Senior engineers deliver production-ready endpoints in 8-12 weeks.
IRPR builds REST APIs using Python (FastAPI), Node.js (Express), Go (Gin), and Java (Spring Boot). We design endpoints with OpenAPI 3.0 specs and deploy on AWS ECS or Kubernetes.
A typical REST API project ships in 8-12 weeks with a fixed price between $80K and $250K. All APIs meet HIPAA, PCI-DSS, or SOC 2 compliance as needed.
Who hires us: CTOs needing a scalable backend for their SaaS platform, product owners requiring PCI-compliant payment APIs, data teams wanting real-time streaming endpoints, and startups building their MVP's API layer.
Types of software we ship.
Payment processing API
PCI-DSS Level 1 compliant payment endpoints with Stripe Connect or Adyen. Supports tokenization, recurring billing, and webhooks.
User authentication API
OAuth 2.0 / OIDC API with JWT tokens, social login (Google, GitHub), and RBAC. Integrates with Auth0 or custom identity providers.
Data aggregation API
Aggregate data from multiple sources (REST, GraphQL, databases) into unified endpoints using Node.js stream processing. Cached with Redis.
Real-time notification API
WebSocket-based or server-sent events API for live notifications. Integrates with Firebase Cloud Messaging, Twilio, or SendGrid.
File upload API
Handle multipart uploads with S3 presigned URLs, image resizing (Sharp), and virus scanning (ClamAV). Supports chunked upload for large files.
Search API
Elasticsearch-based search API with full-text search, faceted filters, and autocomplete. Optimized for sub-100ms response times.
Geolocation API
RESTful geolocation API using PostGIS and Google Maps API. Supports proximity search, geofencing, and reverse geocoding.
CRM integration API
Syncing API for Salesforce, HubSpot, or Zoho CRM. Handles bidirectional sync, deduplication, and field mapping.
We build for every business type.
E-commerce
Healthcare
Fintech
SaaS

Why companies choose IRPR for REST API development
We ship production-ready APIs on time and on budget.
Every REST API IRPR builds is designed to handle production traffic from day one. We use OpenAPI specs to ensure clear contracts between frontend and backend teams.
Our senior engineers have built APIs for companies like Uber and Netflix. They know how to handle rate limiting, caching, and error handling at scale.
IRPR vs generic API development shops
Most agencies overpromise and underdeliver. Here is the difference.
Generic shops often assign junior developers to your project and bill by the hour. They skip compliance reviews and hand over code without documentation.
IRPR does the opposite. You get senior engineers, a fixed price, built-in compliance, and full documentation — all delivered in 8-12 weeks.
- No fixed timeline
- Hourly billing
- No compliance knowledge
- Junior developers
- No post-launch support
- Code not documented
- Fixed price from Roadmap
- Senior engineers only (10+ years)
- Built-in compliance (HIPAA, PCI)
- 8-12 week delivery guarantee
- Full code ownership
- CI/CD and monitoring included
Our REST API development process
From idea to production endpoints in 12 weeks.
We follow a structured process that eliminates guesswork. Each phase has clear deliverables and a go/no-go checkpoint.
You see working endpoints every week. Feedback is incorporated immediately, so there are no surprises at launch.
Every API project ships with these deliverables
You get everything needed to run and maintain your API.
Our standard package includes source code, documentation, tests, and monitoring — all set up and ready to use from day one.
- Source code in GitHub repo
- OpenAPI 3.0 specification
- Postman collection with 50+ endpoints
- Dockerized development environment
- CI/CD pipeline (GitHub Actions)
- Unit and integration tests (pytest, Jest)
- API monitoring dashboard (Datadog)
- Rate limiting and throttling
- Authentication (JWT + OAuth)
- Deployment playbook and runbook

Fixed price, not hourly
Every project receives a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team averages 10+ years of backend and API experience. Each project is staffed with a lead engineer who has built APIs for companies like Uber and Netflix.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs as standard practice. No add-on fees for compliance work.
Production-ready from day one
Every API includes monitoring (Datadog), logging (ELK), and error tracking (Sentry). Uptime SLA of 99.9%.
Full code ownership
You own the entire codebase and intellectual property. No licensing fees or lock-in.
8-12 week delivery
From roadmap to production in 8-12 weeks. We have shipped 200+ products on time with a 98% on-time rate.
