Experienced Backend API Development ConsultantsAPI Development
We build production-ready APIs in 8-12 weeks. Fixed price, no surprises.
IRPR provides experienced backend API development consultants who build production-grade APIs using Node.js, Python, Go, and Rust. We design REST and GraphQL APIs that handle millions of requests per day on AWS, GCP, or Azure.
Each API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. Every API includes automated tests, CI/CD pipelines, and detailed documentation.
Companies hire us when they need senior backend consultants for a new SaaS product, a legacy API migration, a compliance-critical integration, or a real-time data pipeline. Typical buyers are CTOs, VP of Engineering, and Head of Product.
Types of software we ship.
REST API Development
Build stateless REST APIs with Express.js or FastAPI. Includes versioning, rate limiting, and OpenAPI docs.
GraphQL API Development
Design GraphQL schemas with Apollo or Hasura. Supports federated gateways and real-time subscriptions.
Microservices API Architecture
Decompose monoliths into microservices with Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
API Integration Consulting

What Experienced Backend API Development Consultants Deliver
IRPR consultants build APIs that scale from day one with full documentation and monitoring.
Every API project starts with a 2-week Roadmap phase where we define endpoints, data models, and performance targets. We use OpenAPI 3.0 for specification and Postman for testing. The team runs load tests with k6 to verify throughput before launch.
We ship APIs with automated CI/CD on GitHub Actions, error tracking via Sentry, and uptime monitoring via Datadog. Clients get full source code ownership and a 30-day post-launch warranty.
Generic Dev Shop vs. IRPR Backend API Consultants
Not all backend consultants deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often assign junior developers to backend work, skip load testing, and deliver undocumented code. They charge by the hour and scope creep is common.
IRPR assigns senior engineers only, writes automated tests for every endpoint, and delivers OpenAPI docs. We give a fixed price in the Roadmap phase and never bill hourly.
- Junior or mid-level developers on your API
- No load testing before launch
- Undocumented endpoints
- Hourly billing with scope creep
- No CI/CD pipeline
- No post-launch warranty
- Senior engineers with 10+ years experience
- Load testing with k6 before every launch
- OpenAPI 3.0 docs auto-generated
- Fixed price from Roadmap phase (week 2)
- CI/CD with GitHub Actions
- 30-day post-launch warranty included
Our Backend API Development Process
We follow a 4-phase process that delivers a production-ready API in 8-12 weeks.
Phase 1 (Idea) is a 1-week discovery call where we define scope and compliance needs. Phase 2 (Roadmap) is 2 weeks of architecture design, endpoint planning, and a fixed-price quote.
Phase 3 (Product) is 6-8 weeks of development with weekly demos. Phase 4 (Release) includes deployment, monitoring setup, and a 30-day warranty.
What Ships With Every Backend API Project
Every IRPR API project includes these deliverables by default.
We believe in shipping everything your team needs to maintain and scale the API after launch. No hidden handoffs.
All source code, infrastructure configs, and documentation are in your repository from day one.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (90%+ coverage)
- OpenAPI 3.0 specification
- Postman collection for manual testing
- Docker container images
- Infrastructure as code (Terraform or Pulumi)
- Sentry error tracking
- Datadog or CloudWatch monitoring dashboards
- 30-day post-launch support and bug fixes
