Premium Backend API Development FirmAPI Development
We build production-grade backend APIs for high-growth companies. Ship a scalable API in 12 weeks with a fixed price.
We are a premium backend API development firm. We build high-performance APIs using Go, Node.js, Python, and Rust that handle millions of requests per day with sub-50ms latency.
Every project ships in 8 to 12 weeks with a fixed price between $80,000 and $250,000. Our APIs comply with PCI-DSS, HIPAA, or SOC 2 as required by your industry.
CTOs scaling a platform, product managers launching a new API product, and startups needing a robust backend for their mobile app hire us. We work with companies in fintech, healthcare, ecommerce, SaaS, and more.
Types of software we ship.
REST API development
Build stateless, cacheable RESTful APIs that serve web and mobile clients. We use Express.js, FastAPI, or Gin, with OpenAPI documentation.
GraphQL API development
Flexible GraphQL endpoints that let front-end teams query exactly what they need. We use Apollo Server, GraphQL Yoga, and Prisma.
gRPC API development
High-performance protobuf-based APIs for internal microservices. We use Go, gRPC-Gateway, and envoy for HTTP/2 streaming.
Event-driven API (Kafka)
Asynchronous APIs powered by Apache Kafka or RabbitMQ. Ideal for real-time data pipelines and decoupled microservices.
API gateway development
Centralized API gateways with rate limiting, authentication, and routing. We use Kong, NGINX, or AWS API Gateway.
Microservices API architecture
Decompose monolithic backends into independent microservices with clean API contracts. We use Docker, Kubernetes, and gRPC.
WebSocket API development
Real-time, bidirectional APIs for live chat, notifications, and collaborative apps. We use Socket.io, AWS WebSocket API, or Phoenix Channels.
Third-party API integration
Seamlessly connect your system to Stripe, Salesforce, HubSpot, QuickBooks, or any third-party API. We handle OAuth, webhooks, and data mapping.
We build for every business type.

Why companies choose IRPR as their premium backend API development firm
We deliver reliable, secure, and scalable APIs that power your core business.
Our team of senior engineers averages 12+ years of experience. We have shipped over 200 products across 50 countries. 98 percent of our projects deliver on time.
Every API includes automated load testing, Redis caching, and database indexing for sub-100ms response times. We also provide a 99.9 percent uptime SLA.
The difference between a generic dev shop and IRPR
Choosing the right partner for your backend API directly affects your time to market and code quality.
Many agencies start coding without a clear plan. They use hourly billing and keep the code under their own license. You never know the final cost or when you will own the product.
IRPR starts with a fixed-price Roadmap phase in week two. You get full source code ownership, a detailed specification, and a fixed quote before any development begins.
- vague requirements document
- hourly billing with no cap
- no dedicated QA until the end
- code hosted in their repo
- no security audit included
- zero documentation for your team
- detailed Roadmap with 50+ user story points
- fixed price locked at week 2
- automated unit, integration, and load tests from day one
- all source code in your private GitHub repo
- included PCI-DSS, HIPAA, or SOC 2 compliance audit
- Swagger/OpenAPI docs, Postman collection, and runbooks
How we build a premium backend API in 12 weeks
Our process is designed for speed, transparency, and quality.
We follow a four-phase methodology: Discovery, Roadmap, Product, and Release. Each phase has clear checkpoints and deliverables.
Your API goes from concept to production in 8-12 weeks, not months.
Everything that ships with your premium backend API
You get more than code. Every deliverable is built for your team to operate independently.
Our premium backend API development firm includes operational readiness in every project. You can extend, debug, and scale the API without relying on us.
- Source code in your private GitHub repo with full git history
- CI/CD pipeline using GitHub Actions or GitLab CI
- Automated unit tests covering 85%+ of logic
- Load testing script with k6 or Artillery
- API documentation via Swagger/OpenAPI
- Postman collection with environment variables
- Deployment scripts for AWS, GCP, or Azure
- Error monitoring setup with Sentry
- Database migration scripts
- Runbook for common operational tasks
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project receives a fixed quote during the Roadmap phase in week 2. You never see an hourly invoice or a surprise overage charge. 98 percent of our projects stay within budget.
Senior engineers only
Every engineer on your project has 8+ years of experience and a track record of shipping production APIs. We do not outsource or use junior developers.
Full code ownership
You own all source code, documentation, and IP from day one. No licensing fees, no hidden rights. We transfer everything to your GitHub or GitLab repo at launch.
12-week MVP delivery
We ship a working API in 8 to 12 weeks. The typical timeline is 12 weeks for a premium backend API with 5-10 endpoints, authentication, and integrations.
Security by default
Every API includes OWASP Top 10 protections, rate limiting, JWT or OAuth2 authentication, and optional PCI-DSS, HIPAA, or SOC 2 compliance audits.
Ongoing support and maintenance
After launch, we offer a 30-day warranty and optional monthly retainer for bug fixes, performance tuning, and version upgrades. You are never left without a contact.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
