Why Choose a Top Backend API Development Vendor
Numbers speak louder than promises.
IRPR has shipped 200+ products across 50+ countries. Our APIs handle millions of requests per day with 99.9% uptime.
We deliver in 8-12 weeks at a fixed price. 98% of our projects finish on time and on budget.
Generic Vendor vs a Top Backend API Development Vendor
The difference is in the details.
Many agencies promise quality but deliver junior-staffed projects with hidden costs. IRPR is built differently.
We are a top backend API development vendor because we use senior engineers only and give fixed prices upfront.
- hourly billing with unclear scope
- code ownership not guaranteed
- junior or offshore engineers
- no CI/CD pipeline
- manual testing only
- zero compliance documentation
- fixed price after 2-week Roadmap
- full code ownership, no licensing
- senior engineers with 10+ years avg
- CI/CD pipeline built from day one
- automated unit, integration, e2e tests
- HIPAA, PCI-DSS, SOC 2 ready
Our 4-Phase Approach to Backend API Development
From idea to production in 12 weeks.
We break every project into four phases. This eliminates surprises and keeps quality high.
Each phase ends with a clear deliverable, so you always know where we stand.
What Ships with Your Backend API
Every project delivers these artifacts as part of the fixed price.
- Source code in private repo (GitHub/GitLab)
- OpenAPI 3.0 specifications
- Postman collection with environment variables
- CI/CD config (GitHub Actions or GitLab CI)
- Unit & integration tests with 80%+ coverage
- Deployment scripts (Docker, AWS CDK or Terraform)
- Monitoring alerts (Datadog or New Relic)
- API documentation (Redoc or Swagger UI)
- Security audit report (OWASP Top 10)
- Database migration scripts
What we ship in this practice.
Multi-tenant SaaS API
Built a multi-tenant backend for a subscription analytics platform. The API handles 500k requests/day with sub-50ms latency. Reduced time-to-market by 6 weeks using NestJS, PostgreSQL, Stripe, and AWS Fargate.
Real-Time Chat API
Developed a WebSocket-based chat API supporting 10k concurrent connections. Achieved message delivery under 100ms. Used Node.js, Socket.io, Redis, and DynamoDB for the media industry.
Payment Processing API
Created a PCI-DSS Level 1 compliant payment gateway. Processed 2 million transactions in the first month. Used Go, Stripe Connect, and Kubernetes on AWS.
Health Data Exchange API
Built a HIPAA-compliant API for a telemedicine platform. Exchanged FHIR resources between 3 EHR systems. Passed audit in 2 weeks. Used FastAPI, HL7 FHIR, and AWS HealthLake.
Logistics Routing API
Designed a route optimization API for a delivery fleet. Reduced fuel costs by 18% and on-time deliveries improved to 94%. Used Python, Mapbox, PostgreSQL, and Redis.
E-Commerce Checkout API
Implemented a headless checkout API for a fashion retailer. Increased conversion rate by 12% through faster page loads and smart error handling. Used Rails, Stripe, and Memcache.
