Why You Need an Expert API Development Firm
A poorly designed API costs you time, money, and security. IRPR builds APIs that scale from day one.
Most in-house teams lack the deep API security and performance expertise needed for production systems. IRPR has shipped 200+ APIs across 50 countries. We know how to handle OWASP Top 10, rate limiting, and database connection pooling.
We use a fixed-price model so you know the cost upfront. In the Roadmap phase (week 2), we define every endpoint, data model, and integration. No surprises. No hourly billing.
Generic Dev Shop vs. IRPR: The API Development Difference
Not all API development firms are equal. Here is what sets IRPR apart.
Generic dev shops treat your API as a side project. They use boilerplate code, skip security audits, and deliver late. IRPR treats your API as the core product. We write custom code, run penetration tests, and ship on time.
Our senior engineers have built APIs for healthcare, fintech, and ecommerce. We know PCI-DSS, HIPAA, and SOC 2 requirements. You get a production-ready API with monitoring, logging, and documentation.
- No API security audit
- No rate limiting or throttling
- No CI/CD pipeline
- No API documentation
- Hourly billing with scope creep
- No compliance knowledge
- OWASP Top 10 security audit
- Rate limiting and caching built in
- CI/CD on GitHub Actions
- Interactive Swagger UI docs
- Fixed price, no surprises
- HIPAA, PCI-DSS, SOC 2 ready
Our API Development Process: 4 Phases
We follow a structured process to deliver your API on time and on budget.
Every project starts with a 1-week kickoff where we align on goals, tech stack, and compliance needs. Then we move through four phases: Idea, Roadmap, Product, Release.
The Roadmap phase (week 2) produces a detailed spec with every endpoint, data model, and integration. You approve the spec before we write a single line of code.
What Ships with Every API Project
You get more than just code. Every API project includes these deliverables by default.
We believe in full transparency. You own everything we build. No black boxes, no proprietary frameworks.
Every project includes a CI/CD pipeline, monitoring, and documentation. You can deploy to any cloud provider: AWS, GCP, or Azure.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Interactive API docs (Swagger UI)
- Postman collection with examples
- Unit and integration tests (90%+ coverage)
- Rate limiting and caching configuration
- Security audit report (OWASP Top 10)
- 30-day post-launch warranty
What we ship in this practice.
HIPAA-Compliant Patient Data API

MLS Data Integration API
Developed an API that aggregates MLS data from 50+ sources for a real estate platform. Used Python, FastAPI, and Elasticsearch. Reduced data refresh time from 24 hours to 15 minutes.
AI Chatbot API with NLP
Built a gRPC API for an AI chatbot that handles 100,000 conversations per day. Used Go, TensorFlow, and Kafka. Reduced response time to under 200ms. Improved customer satisfaction by 25%.
Why teams hire us.
Fixed price, not hourly
Every API 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 start building.
Senior engineers only
Every engineer at IRPR has 10+ years of experience. No juniors, no offshore teams. Your API is built by someone who has shipped production APIs for companies like yours.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into every API from day one. No retrofitting. No last-minute audits. Your API is ready for regulated industries.
Full code ownership
You own every line of code we write. No proprietary frameworks, no licensing fees. We hand over the source code, CI/CD pipeline, and documentation at the end of the project.
8-12 week delivery
We ship production-ready APIs in 8-12 weeks. Our process is optimized for speed without sacrificing quality. You get a working API faster than hiring an in-house team.
Post-launch support
Every project includes a 30-day warranty. We fix bugs, answer questions, and help with deployment. After that, we offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
