Why IRPR is the best backend API development studio
Our track record proves it.
IRPR has shipped over 200 API projects across 50 countries. Our APIs handle 10,000 requests per second on average.
We deliver on time 98% of the time. Every API comes with automated testing and monitoring.
The difference between a generic backend shop and IRPR
How we stand out.
Generic shops often use junior engineers and bill hourly. You get unexpected delays and bloated costs.
IRPR assigns a senior architect to design your API. We fix the price upfront and ship in 8-12 weeks.
- Hourly billing leads to cost overruns
- Junior engineers unfamiliar with your stack
- No fixed timeline
- API docs are an afterthought
- No security compliance
- Code ownership unclear
- Fixed price from the start
- Senior engineers only with 10+ years experience
- 8-12 week delivery guarantee
- OpenAPI 3.0 docs shipped
- SOC 2 and HIPAA compliant
- Full code ownership transferred
Our API development process in 4 phases
From idea to production API.
We follow a structured 4-phase process that de-risks your project.
What ships with your API
Every project includes these deliverables.
No surprises. Your team gets everything needed to maintain and scale the API.
- Complete source code in your GitHub or GitLab repo
- OpenAPI 3.0 specification (Swagger)
- Postman collection with sample requests
- CI/CD pipeline using GitHub Actions or GitLab CI
- Docker image for easy deployment
- Integration tests with 90%+ code coverage
- Sentry error tracking
- Datadog or New Relic monitoring dashboard
- Deployment runbook with rollback steps
- Architecture decision record (ADR) document
What we ship in this practice.
Multi-tenant SaaS API
Developed a GraphQL API for a project management tool supporting 500 tenants using Apollo Server and MongoDB. Cut onboarding time from 2 weeks to 2 days.
HIPAA-compliant patient data API
Built a RESTful API for a telehealth platform using Flask and PostgreSQL. Achieved HIPAA compliance and reduced data retrieval time by 40%.
Payment gateway integration API
Created an API layer connecting a marketplace to Stripe and PayPal using Node.js. Handled 50,000 daily transactions with 99.99% uptime.
Real-time inventory sync API
Designed a WebSocket API for a retail chain to sync inventory across 200 stores. Reduced overselling by 95%.
Microservices migration for media platform
Migrated a monolithic Ruby on Rails app to a microservices architecture using Go and Kubernetes. Cut deployment time from 2 hours to 10 minutes.
Event-driven analytics API
Built an event-driven API using AWS Lambda and Kafka to process 10 million records/day for a marketing analytics platform. Improved query performance by 300%.
Why teams hire us.
Fixed price, not hourly
Every API project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
Our team consists of engineers with 10+ years of backend experience. No juniors, no outsourced teams.
8-12 week delivery
We ship your API in 8 to 12 weeks from kickoff. 98% of our projects finish on time.
Full code ownership
You own the source code, docs, and IP from day one. No licensing fees or lock-in.
Compliance built in
We build APIs that comply with SOC 2, HIPAA, PCI-DSS, and GDPR. Our security checklist is part of every project.
Post-launch support
We provide 30 days of free support after launch. Your API is monitored, tested, and documented.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
