We build backend systems that handle 10M+ requests per day. Fixed pricing, 8-12 week delivery, full code ownership.
IRPR builds backend systems using Go, Node.js, Python, and Rust. We design REST and gRPC APIs, event-driven architectures with Kafka, and serverless backends on AWS Lambda.
A typical MVP ships in 8-12 weeks with $80K-$250K fixed pricing. Every system includes CI/CD, automated testing, and compliance controls for HIPAA, PCI-DSS, and SOC 2.
CTOs needing a scalable backend after a prototype fail. Tech leads who need to ship a compliant SaaS platform. Founders who want fixed pricing without scope creep.
Types of software we ship.
Custom backend API development
Build REST or gRPC APIs using Node.js and Express. Includes Swagger docs and rate limiting for production traffic.
Microservices architecture
Decompose monoliths into independent services with Docker and Kubernetes. Each service scales independently.
Real-time data pipeline
Stream data with Kafka and process in real-time using Apache Flink. Latency under 100ms.
Event-driven system
Use RabbitMQ or AWS SQS to decouple services. Supports exactly-once delivery and dead letter queues.
Serverless backend
Run functions on AWS Lambda with API Gateway. Pay per request, auto-scale to millions of users.
GraphQL API
Implement GraphQL with Apollo Server. Reduces over-fetching and enables frontend-driven queries.

Why hire an experienced backend development vendor
A dedicated vendor brings architecture expertise, compliance knowledge, and delivery discipline.
IRPR's team averages 10+ years of backend engineering experience. We have built systems for fintech, healthcare, and ecommerce that process millions of requests per day. Every project starts with an architecture review to ensure scalability and security.
We follow a fixed-price model that eliminates budget surprises. The Roadmap phase locks scope and price after two weeks of discovery. This process has delivered 200+ products with 98% on-time delivery across 50+ countries.
How IRPR differs from generic development shops
Generic shops bill hourly and skip architecture. IRPR fixes price, process, and proof first.
Most backend projects fail because of unclear requirements and hourly billing that rewards slow work. IRPR uses a two-week Roadmap phase to define everything: endpoints, data model, compliance needs, and infrastructure. You get a fixed price before any code is written.
Our team is 100% senior engineers with experience at companies like Google and Amazon. We do not outsource or use junior developers. Every system includes CI/CD, automated testing, monitoring, and a post-launch support period of 2 years.
- Hourly billing with no price cap
- No architecture review upfront
- Junior developers writing production code
- No CI/CD pipeline
- Only frontend focus, backend is afterthought
- No post-launch support
- Fixed price after Roadmap phase
- Architecture review with senior engineers
- 10+ year engineers only
- CI/CD, automated testing, monitoring included
- Backend-first design with scalability in mind
- 2 years of support included
Our backend development process
We move from idea to production in four phases, each with clear deliverables.
The process starts with a Roadmap phase where we define the API spec, data model, and infrastructure plan. You approve the scope and price before any development begins. This eliminates surprises.
During the Product phase we build the system iteratively with weekly demos. The Release phase includes load testing, security review, and production deployment. Finally, we provide 2 years of maintenance and support.
What ships with your backend
Every project delivers a complete, production-ready backend with full documentation and automation.
We do not just hand off code. You get the entire infrastructure as code, a CI/CD pipeline, monitoring, and security tools pre-configured. Your team can start extending the system on day one.
All code is in your GitHub or GitLab repo. We provide a Postman collection for every API, a deployment runbook, and load test results. You own everything - no licensing fees or hidden costs.
- Source code in your GitHub repo with full history
- Docker containerization for every service
- CI/CD pipeline using GitHub Actions or GitLab CI
- Sentry error tracking for real-time issue alerts
- Postman collection with all API endpoints
- Terraform infrastructure as code for AWS/GCP/Azure
- Load testing results with JMeter or k6
- Security audit report (OWASP top 10 checks)
- API documentation with Swagger/OpenAPI
- Deployment runbook with rollback procedures
What we ship in this practice.
