Professional API Development PartnerAPI Development
Build secure, scalable APIs in 12 weeks with fixed pricing. 200+ products shipped across 50+ countries.
IRPR builds professional APIs for companies that need reliable, secure integrations. We use Node.js, Go, Python, and Rust to create REST, GraphQL, and gRPC endpoints that handle millions of requests per day.
Every project ships with documented endpoints, automated tests, and CI/CD pipelines. Timeline is 12-14 weeks for a production-grade API. Pricing ranges from $80K to $250K depending on complexity. We comply with HIPAA, PCI-DSS, and SOC 2 standards.
CTOs hire us to replace fragile internal APIs. Product managers hire us to build API-first platforms. SaaS founders hire us to create public APIs that drive revenue. Engineering leads hire us to migrate monolithic backends to microservices.
Types of software we ship.
REST API Development

Why You Need a Professional API Development Partner
A poorly designed API costs you time, money, and developer trust.
APIs are the backbone of modern software. If your API is slow, undocumented, or insecure, every team that depends on it suffers. IRPR builds APIs that are fast, well-documented, and secure from day one.
We have shipped over 200 APIs for clients in healthcare, fintech, and ecommerce. Our APIs handle up to 10,000 requests per second with 99.9% uptime. Every endpoint includes automated tests, rate limiting, and monitoring with Datadog.
Generic Dev Shop vs IRPR: The API Development Difference
Not all API development partners deliver the same quality.
Many agencies rush to code without a solid architecture. They skip documentation, ignore security, and deliver APIs that break under load. IRPR follows a structured process that guarantees reliability.
We start with a 2-week Roadmap phase to define endpoints, data models, and security requirements. Then we build in 2-week sprints with continuous integration and deployment. Every API ships with Postman collections and Swagger docs.
- No API design document before coding
- Missing rate limiting and authentication
- No automated tests for endpoints
- No monitoring or alerting setup
- Unclear pricing with hourly billing
- No post-launch support included
- OpenAPI 3.0 spec approved in week 2
- JWT + OAuth 2.0 + rate limiting built in
- 100% endpoint test coverage with Jest
- Datadog monitoring and PagerDuty alerts
- Fixed price from $80K to $250K
- 2 months of post-launch support included
Our API Development Process
We follow a 4-phase process that guarantees on-time delivery.
Every project starts with a 2-week Roadmap phase where we define the API contract, data flow, and security architecture. You get a fixed price and timeline before any code is written.
During the Product phase, we build in 2-week sprints with daily standups and weekly demos. You see working endpoints every Friday. The Release phase includes load testing, security audit, and deployment to your infrastructure.
What Ships with Every API
You get everything needed to maintain and scale your API.
IRPR delivers more than just code. Every project includes documentation, monitoring, and deployment infrastructure. Your team can take over immediately.
We provide full source code ownership, a private Git repository, and a CI/CD pipeline. You also get a runbook for incident response and a 2-month support period.
- Source code in your private GitHub/GitLab repo
- OpenAPI 3.0 specification document
- Postman collection with example requests
- CI/CD pipeline with GitHub Actions or GitLab CI
- Dockerized API with docker-compose for local dev
- Sentry error tracking and Datadog monitoring
- Load test results with k6 or Locust
- Security audit report (OWASP Top 10)
- Deployment runbook and incident response guide
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices. You know the total cost before we write a single line of code.
Senior engineers only
All IRPR engineers have 8+ years of experience building APIs. Your project is led by a staff engineer who has shipped production APIs at companies like Google, Stripe, and Uber.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our security checklist covers encryption at rest and in transit, access controls, and audit logging.
Documentation you can use
Every API ships with OpenAPI 3.0 specs, Postman collections, and a developer guide. Your team can integrate with your API in hours, not days.
Monitoring from day one
We set up Datadog dashboards, Sentry error tracking, and PagerDuty alerts before launch. You get real-time visibility into API performance and errors.
Full code ownership
You own all source code, documentation, and infrastructure config. No lock-in, no licensing fees. You can take the project in-house or to another agency at any time.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
