Experienced Backend API Development CompanyBackend API
We build production-ready APIs that handle millions of requests. Senior engineers deliver your MVP in 8-12 weeks with fixed pricing.
IRPR builds backend APIs for web and mobile apps using Node.js, Python, Go, and TypeScript. We design RESTful and GraphQL endpoints with PostgreSQL, Redis, and AWS Lambda.
A typical API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2).
We work with CTOs at Series A startups who need a scalable API fast, product managers at mid-market companies integrating third-party services, and engineering leads at enterprises modernizing legacy systems.

Why choose an experienced backend API development company?
IRPR has shipped over 200 production APIs for clients worldwide.
Our APIs handle 10M+ requests daily with 99.9% uptime. We use automated CI/CD pipelines and monitoring with Datadog and Sentry.
Every project includes load testing, security audits, and documentation. We deliver source code and infrastructure as code.
How we compare to generic development shops
Not all API developers deliver the same quality.
Generic shops often use junior developers and hourly billing. IRPR assigns senior engineers and fixed pricing from day one.
We write automated tests, enforce code reviews, and deploy with zero-downtime strategies.
- Hourly billing with no cap
- Junior or mid-level developers
- No load testing
- Minimal documentation
- Shared code ownership
- No post-launch support
- Fixed price, no surprises
- Senior engineers only (10+ years)
- Load testing to 100K concurrent users
- OpenAPI 3.0 documentation included
- Full code ownership
- 30 days of post-launch support
Our 4-phase process for building your API
We move from idea to production in 8-12 weeks.
Each phase has clear deliverables and a fixed timeline. You see progress every week.
We use agile sprints with daily standups and weekly demos.

All code, infrastructure, and documentation are yours. No hidden dependencies.
We set up monitoring and error tracking so you can sleep soundly.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- OpenAPI 3.0 specification
- Postman collection for testing
- Sentry error tracking
- Datadog monitoring dashboard
- Load test report (k6)
- Security audit report (OWASP)
- Deployment scripts (Terraform or Pulumi)
- 30 days of post-launch support
