Premium Backend API Development VendorBackend API
We build production-grade APIs that handle millions of requests. Fixed pricing, 8-12 week delivery, full code ownership.
IRPR is a premium backend API development vendor. We build APIs using Node.js, Python (FastAPI), Go, and Rust. Our APIs power web apps, mobile apps, and microservices architectures with Redis caching, PostgreSQL, and Kafka for event streaming.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. You get full ownership of the code, CI/CD pipelines, and AWS/GCP infrastructure.
CTOs hire us when their in-house team is too slow. Startup founders hire us to ship their MVP before the next funding round. Enterprise architects hire us to replace legacy APIs with modern, scalable endpoints. Product managers hire us to integrate third-party services like Stripe, Salesforce, and Twilio.
Types of software we ship.
REST API development
Standard RESTful APIs with OpenAPI 3.0 docs. We use Express.js, FastAPI, and Spring Boot for enterprise-grade endpoints.
GraphQL API development
GraphQL APIs with Apollo Server or Hasura. Includes schema design, resolver optimization, and subscription support.
Microservices API development
Decoupled microservices with Docker, Kubernetes, and gRPC. Each service has its own database and CI/CD pipeline.
Webhook API development
Webhook systems that deliver real-time events to Slack, Stripe, Shopify, and custom endpoints. Includes retry logic and idempotency.
Third-party API integration
Connect your platform to Salesforce, HubSpot, QuickBooks, Twilio, and 50+ other services. We handle OAuth, rate limiting, and error handling.

Why choose a premium backend API development vendor
Not all API shops are equal. A premium vendor delivers reliability, security, and speed.
IRPR has shipped over 200 API projects across 50 countries. Our APIs handle 10,000 requests per second on average. We use Redis for caching, PostgreSQL for persistence, and Sentry for error tracking. Every API ships with automated tests covering 95% of endpoints.
We follow strict coding standards. Every pull request gets reviewed by a senior engineer. We enforce rate limiting, authentication (JWT, OAuth 2.0), and input validation. Our APIs pass OWASP Top 10 security checks before deployment.
Generic dev shop vs premium backend API development vendor
The difference between a cheap API and a production-grade API is measurable.
Generic shops reuse boilerplate code and skip documentation. They deliver on time but leave you with unmaintainable spaghetti. IRPR treats every API as a product, not a task.
We write integration tests for every endpoint. We generate OpenAPI 3.0 docs automatically. We set up monitoring with Datadog and alerting with PagerDuty. Your API is ready for millions of users from day one.
- No automated tests or low coverage
- No API documentation or outdated
- No rate limiting or security checks
- No CI/CD pipeline
- No monitoring or alerting
- Hourly billing with scope creep
- 95% test coverage with CI enforcement
- Auto-generated OpenAPI 3.0 docs
- OWASP Top 10 security checks
- GitHub Actions CI/CD pipeline
- Datadog monitoring + PagerDuty alerts
- Fixed price from Roadmap phase
How we build your premium backend API
Our process is designed to eliminate surprises. You see working endpoints every 2 weeks.
We start with a 2-week Roadmap phase. We define the API contract, data model, and integration points. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints. Every sprint ends with a deployable API endpoint. You review and test live on staging. We handle deployment to AWS, GCP, or Azure.
What ships with your premium backend API
You don't just get code. You get a production-ready system with all the tooling.
Every API project includes infrastructure as code. We use Terraform for AWS or Pulumi for GCP. Your team can deploy new versions in minutes.
We also include a developer portal with API keys, usage analytics, and documentation. Your customers can integrate in hours, not weeks.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions
- OpenAPI 3.0 documentation
- Postman collection for testing
- Sentry error tracking
- Datadog monitoring dashboard
- Load test results (k6 or Artillery)
- Terraform or Pulumi infrastructure scripts
- Docker Compose for local development
- Security audit report (OWASP Top 10)

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
IRPR hires only engineers with 7+ years of experience. No juniors, no offshore teams. Every engineer has built production APIs serving at least 100,000 users.
Full code ownership
You own the source code, documentation, and infrastructure scripts from day one. No proprietary frameworks, no vendor lock-in. We push everything to your GitHub repo.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. We handle encryption, audit logs, and access controls. You don't need to retrofit compliance later.
12-week delivery guarantee
Our average MVP ships in 8-12 weeks. We use agile sprints with bi-weekly demos. If we miss the timeline, you don't pay for the extra weeks.
Post-launch support
We include 30 days of post-launch support. We monitor uptime, fix bugs, and optimize performance. After that, you can extend support monthly or yearly.
