Professional Backend App Development StudioBackend App
We build backend systems that handle billions of requests per month. Our senior engineers ship production-ready APIs and microservices in 8-12 weeks.
IRPR is a professional backend app development studio that engineers scalable, secure, and maintainable server-side applications. We specialize in Node.js, Python, Go, and use PostgreSQL, MongoDB, Redis, and cloud-native services from AWS and GCP.
Every backend project ships with a production-ready API, automated CI/CD pipeline, infrastructure as code, and 24/7 monitoring. Typical timelines run 8-12 weeks with fixed pricing from $80K to $250K depending on complexity. We support compliance standards like HIPAA, PCI-DSS, SOC 2, and GDPR.
Startups seeking a reliable engineering partner for their next funding round, mid-market companies modernizing legacy backend systems, SaaS founders building multi-tenant architectures, and enterprise teams scaling to millions of users hire IRPR.
Types of software we ship.
REST API Development
High-performance RESTful APIs with authentication, rate limiting, and auto-generated Swagger documentation for seamless integration.

Server-side logic for iOS and Android apps with push notifications via Firebase/APNs, offline sync, and user authentication.
SaaS Backend Infrastructure
Multi-tenant databases, billing integrations (Stripe), admin dashboards, and tenant isolation for SaaS platforms.
Cloud-Native Backend Solutions
Serverless functions (AWS Lambda), containerized services with Kubernetes, and auto-scaling infrastructure designed for cost-efficiency.
We build for every business type.
Startups and SaaS companies
Enterprise and institutions
Mobile and web apps
Data and AI applications

Backend Performance Metrics That Matter
We measure success in uptime, speed, and developer velocity.
Our backends handle over 4,000 transactions per second on average, with P95 response times under 50ms. Every API endpoint is load-tested with k6 before release.
We maintain 99.99% uptime across all production systems by using multi-region deployments, automated failover, and real-time monitoring from Datadog and Sentry.
Generic Development Shop vs. IRPR
Not all backend teams deliver the same quality.
Many development shops promise backend expertise but hand your project to junior developers with no clear process. You end up with code you don't own, unpredictable costs, and missing infrastructure.
IRPR works differently. We assign senior engineers only, follow a fixed-price roadmap, and deliver a production-ready system with full ownership from day one.
- Unclear ownership of code
- No fixed pricing
- Junior developers on your project
- No CI/CD pipeline
- No monitoring or alerting
- Documentation as an afterthought
- Full source code ownership
- Fixed price per phase
- Senior engineers only
- Automated testing and deployment
- Sentry + Datadog monitoring by default
- Auto-generated API docs (Swagger/OpenAPI)
Our Backend Development Process
We follow a repeatable 4-phase framework.
Our framework, called Idea -> Roadmap -> Product -> Release, ensures every project starts with a clear plan and ends with a production-grade system. Each phase has specific deliverables and checkpoints.
Everything That Ships with Your Backend
No hidden deliverables. Every project includes these by default.
We believe in transparency. From the moment we start, we build infrastructure and documentation that you can use immediately after handover.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Infrastructure as code (Terraform or AWS CDK)
- API documentation via Swagger/OpenAPI
- Health checks and monitoring (Datadog, Sentry)
- Error tracking and alerting
- Load testing results (k6 or Artillery)
- Docker containers for local development
- Postman collections for API testing
- Deployment runbook and architecture diagram
What we ship in this practice.
Real-Time Chat Backend for EdTech Platform
Built a WebSocket-based chat service supporting 50,000 concurrent users. Reduced message delivery latency to under 100ms. Tech stack: Node.js, Socket.io, Redis, PostgreSQL, Kubernetes.
Ecommerce Checkout API for Retailer
Engineered a PCI-compliant checkout system processing 10,000 orders per hour. Integrated with Stripe, Shopify, and custom warehouse API. Reduced checkout failures by 35%.
SaaS Multi-Tenant Backend for B2B Platform
Designed a single-codebase multi-tenant architecture handling 500+ tenants. Implemented row-level security and isolated billing per tenant. Tech stack: Python, Django, PostgreSQL, AWS RDS.
Data Pipeline for IoT Device Manufacturer
Built a real-time ingestion pipeline for 1 million devices, processing 2 TB of sensor data daily. Used Kafka, Spark, and S3 for cost-effective storage.
HIPAA-Compliant Backend for Healthcare App
Created a secure backend for patient record sharing, with encryption at rest and in transit, audit logs, and role-based access. Passed HIPAA audit with zero findings.
Marketplace Backend with Payment Escrow
Developed a marketplace backend supporting 100,000 listings with escrow payments, dispute resolution, and real-time notifications. Integrated with Stripe Connect and Twilio.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing means no surprise invoices. Our average project costs $80K to $250K.
Senior Engineers Only
We have no junior or offshore developers. Every engineer has 8+ years of experience and has shipped at least 10 production backends. You talk directly to the person building your system.
Full Code Ownership
You own 100% of the source code, infrastructure scripts, and documentation from day one. We never charge licensing fees or lock you into our stack.
Built for Scale from the Start
We design backends to handle 10x your initial traffic using horizontal scaling, caching, and database replication. Our systems average 99.9% uptime.
Production-Ready Deliverables
No half-baked prototypes. Every backend ships with automated CI/CD, monitoring, error tracking, and deployment runbooks. Most clients deploy to production in week 8.
Compliance Built In
We have built backends for HIPAA, PCI-DSS, SOC 2, and GDPR environments. If your industry requires compliance, we include it in the architecture from week 1.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
