Expert Backend API Development DevelopersBackend API
We build scalable REST and GraphQL APIs that ship in 8-12 weeks. Get a fixed price and full code ownership from day one.
IRPR builds custom backend APIs for web and mobile applications. We use Node.js, Python (Django/FastAPI), Go, and PostgreSQL to create secure, high-performance data layers.
Every project includes a 2-week Roadmap phase to define scope and architecture. Fixed pricing ranges from $80K to $250K. We handle compliance like HIPAA, PCI-DSS, SOC 2, and FERPA.
This service is for CTOs of startups needing a scalable backend, product managers at mid-market companies integrating third-party services, and tech leads at enterprises migrating from monoliths to microservices.

Why choose expert backend API development developers from IRPR?
We ship production-grade APIs with measurable outcomes.
IRPR has delivered over 200 custom APIs across 50 countries. Our average timeline is 8-12 weeks, and 98% of projects launch on schedule.
Every API includes monitoring, logging, and CI/CD pipelines. We guarantee 99.9% uptime for production deployments.
The difference between IRPR and a generic dev shop
Not all API developers work the same way.
Generic dev shops bill by the hour and start building without a clear plan. That leads to surprise costs and missed deadlines.
IRPR uses a fixed-price model after a 2-week Roadmap. You know the cost, timeline, and deliverables before any code is written.
- No fixed pricing - hourly billing
- Unclear ownership of code and IP
- Junior developers assigned to project
- Long discovery phases (months)
- No compliance guarantees
- Rebuilding from scratch due to poor architecture
- Fixed price after 2-week Roadmap
- Full code ownership from day one
- Senior engineers only (10+ years exp)
- 8-12 week delivery
- HIPAA, PCI, SOC 2 compliance built in
- CI/CD, monitoring, scalable architecture included
Our process for building your backend API
We follow a repeatable 4-phase process to de-risk your project.
From idea to production, each phase has clear deliverables and milestones. You see progress every week.
No black boxes - every decision is documented and you approve the plan before we build.
What you get when you work with IRPR
Every API project ships with these deliverables included in the fixed price.
You don't just get code - you get a production-ready system with all the tooling needed to run it confidently.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerized microservices with docker-compose
- OpenAPI/Swagger documentation
- Sentry error tracking
- Datadog monitoring dashboards
- Load testing results (k6 or Artillery)
- Security audit report (OWASP Top 10)
- Deployment runbook with rollback steps
- 30 days of post-launch support
