What a Professional REST API Development Partner Delivers
We don't just write endpoints. We ship reliable, documented, and secure APIs that your team can trust.
IRPR has delivered over 200 APIs for clients in fintech, healthcare, and SaaS. Our average delivery is 12 weeks with a 98% on-time record. Every API includes automated tests, CI/CD pipelines, and monitoring.
You get full ownership of the source code, an OpenAPI spec, Postman collections, and deployment scripts. No black boxes. No ongoing license fees.
Comparison: IRPR vs. Generic Dev Shop
Hiring a freelance developer or generic agency often leads to hidden costs and delayed timelines. Here's how IRPR is different.
Generic shops bill by the hour and change requirements mid-project. IRPR gives you a fixed price after a 1-week Roadmap phase. No surprises.
We build for compliance from day one. Every API goes through security review and load testing before deployment. Generic shops skip this and leave you with technical debt.
- Weekly billing with no cap
- No security audits (PCI, HIPAA)
- Delayed timelines by 2-4 months
- No CI/CD or automated testing
- No post-launch support beyond 14 days
- Vague requirements that change scope
- Fixed price after Roadmap phase
- HIPAA, PCI-DSS, SOC 2 built-in
- 8-12 week delivery guarantee
- Automated CI/CD with GitHub Actions
- 30-day post-launch support included
- Clear roadmap with milestones upfront
Our Process: From Idea to REST API in 4 Phases
We follow a structured process that keeps every project on time and on budget.
Phase 1: Discovery & Architecture. We map your data models, endpoints, and security requirements. You get a system design document with specific tools (PostgreSQL, Redis, AWS ECS).
Phase 2: Roadmap & Pricing. We define every milestone and provide a fixed price. No hourly billing. You approve the plan before we write a line of code.
What Ships with Every REST API
Every project includes these deliverables. No hidden extras.
You own everything we build. Source code, deployment scripts, and documentation are yours. No licensing fees.
We also set up monitoring, error tracking, and performance dashboards so you can operate the API from day one.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- OpenAPI 3.0 specification (Swagger)
- Postman collection with example requests
- Database schema and migration scripts (PostgreSQL)
- Load test results (k6 or Artillery)
- Deployment scripts for AWS ECS, GCP Cloud Run, or Azure AKS
- API key management and rate limiting (Redis-based)
- 30-day post-launch support with SLA
