Why you need a premium backend API development team
Building an API that can scale from day one requires senior engineers with production experience.
Most startups waste months rewriting APIs after launch. Our team designs for scaling from the start, using patterns like CQRS and event sourcing.
We have shipped 200+ APIs across fintech, healthcare, and SaaS. 98% of projects delivered on time with fixed pricing.
How we build APIs differently
We do not cut corners on documentation, error handling, or monitoring.
Many dev shops build APIs that lack tests, logging, or rate limiting. They hand off incomplete code with no docs.
IRPR ships a production-ready API with unit and integration tests, OpenAPI spec, Sentry error tracking, and Datadog dashboards.
- No documentation beyond Swagger stub
- No integration tests
- No rate limiting
- No health endpoints
- No deployment scripts
- No SLA for uptime
- Full OpenAPI 3.0 spec with examples
- 90%+ test coverage
- Rate limiting with Redis
- Health check and readiness probes
- CI/CD pipeline with GitHub Actions
- 99.9% uptime SLA
Our API development process
From discovery to deployment, we follow a proven 4-phase framework.
Phase 1: Discovery and architecture design. We map all endpoints, data models, and auth flows.
Phase 4: Release and monitoring. We deploy to production with Grafana dashboards and Coverage.
What ships with every API
You get more than just code - you get a complete production system.
Every project includes these deliverables by default.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification (YAML/JSON)
- Postman collection with all endpoints
- Database schema and migration scripts
- CI/CD pipeline on GitHub Actions
- Sentry error tracking integration
- Datadog or Grafana monitoring dashboards
- Load test results with k6
- One-pager system architecture diagram
- 30-day post-launch support
What we ship in this practice.
Subscription billing API for SaaS
Built a REST API for a usage-based billing platform using Node.js, Stripe, and PostgreSQL. Reduced failed payments by 40% and cut billing cycle time from 3 days to real-time.
Patient data API for telemedicine
Developed a HIPAA-compliant GraphQL API for a telehealth startup using Apollo Server and MongoDB. Handles 5K+ requests/min with 200ms latency.
Payment processing API for fintech
Created a PCI-DSS compliant payment orchestration API with Go and AWS Lambda. Integrated 8 payment gateways and reduced integration time for merchants by 70%.

Built a real-time inventory sync API using Python, Redis, and RabbitMQ for a multi-warehouse retailer. Eliminated overselling and saved $200K/year in lost orders.
Loyalty points API for retail
Designed a high-throughput API for a loyalty program with PostgreSQL and Kafka. Processes 1M+ transactions per day with 99.99% uptime.
CRM integration API for real estate
Built an API that syncs MLS listings to CRM systems using Node.js and Google Sheets API. Reduced manual data entry by 12 hours per week per agent.
