Expert Backend App Development AgencyBackend App
We build the server-side systems that power your product. Node.js, Python, Go — deployed in 12 weeks with fixed pricing.
IRPR builds backend applications using Node.js, Python, and Go with PostgreSQL or MongoDB, deployed on AWS or GCP. We design REST and GraphQL APIs, microservices architectures, and real-time systems.
Every project ships in 12-14 weeks with a fixed price between $80K and $250K. We handle compliance (SOC 2, HIPAA, PCI-DSS) and include CI/CD, monitoring, and documentation by default.
Our clients are CTOs scaling platforms, founders needing API-first architecture, enterprise teams replacing legacy backend systems, and fintech startups requiring PCI-DSS compliant server infrastructure.
Types of software we ship.
REST API Development
Build JSON-based APIs for web and mobile clients. Uses Express.js, FastAPI, or Gin with JWT authentication and rate limiting.
GraphQL API Development
Flexible query endpoints for complex data needs. Built with Apollo Server, Prisma, and PostgreSQL with resolver caching.
Microservices Architecture
Decoupled service mesh with RabbitMQ or Kafka for event-driven communication. Each service containerized and independently scalable.
Cloud-Native Backend
Fully managed services on AWS (Lambda, ECS, RDS) or GCP (Cloud Run, Cloud SQL). Infrastructure as code with Terraform.
Serverless Backend
Zero-maintenance functions using AWS Lambda or Google Cloud Functions. Ideal for bursty workloads and cost efficiency.
Real-Time Backend (WebSockets)
Live data streaming for chat, notifications, and collaborative tools. Built with Socket.io, Redis Pub/Sub, and auto-scaling.
Backend for Mobile Apps
Push notifications, user authentication, and cloud sync. Uses Firebase, AWS Amplify, or custom Node.js with MongoDB.
Custom Backend as a Service
White-label BaaS exposing user management, file storage, and analytics APIs. Deployed on Kubernetes with multi-tenant isolation.
We build for every business type.

Why speed and reliability matter for your backend
A slow, unreliable backend kills user trust. We ship in 12 weeks with 99.9% uptime.
IRPR has delivered 200+ backend projects across 50 countries. Our average delivery time is 12 weeks from kickoff to production deployment. We use CI/CD pipelines with automated tests and blue-green deployments to minimize downtime.
Every backend includes Sentry error tracking, CloudWatch or Datadog monitoring, and automated scaling policies. We guarantee 99.9% uptime through multi-AZ deployments and disaster recovery plans.
How IRPR differs from other backend agencies
Most agencies bill hourly and miss deadlines. We fix scope and price before building.
After a 2-week Roadmap phase (week 2), you get a fixed price and a clear timeline. No hidden costs, no scope creep. Every project has a dedicated senior engineer who writes all code.
We handle compliance from day one. For fintech, we implement PCI-DSS tokenization. For healthcare, we sign BAAs and audit all data access. For SaaS, we prepare for SOC 2 Type II.
- Hourly billing with no cap
- Unclear timelines (6-12 months)
- Junior developers on your project
- No compliance expertise
- Code owned by the agency
- No monitoring or CI/CD included
- Fixed price after Roadmap phase
- 12-14 week delivery guaranteed
- Senior engineers only (10+ years)
- HIPAA, PCI-DSS, SOC 2 built in
- You own 100% of the source code
- Sentry, CloudWatch, CI/CD all included
Our 4-phase backend development process
Every project follows the same proven framework: Idea, Roadmap, Product, Release.
In the Idea phase (week 1), we define the backend's core API surface, data model, and cloud architecture. You get a one-page spec and a ballpark estimate.
The Roadmap phase (week 2) produces a detailed technical specification with endpoints, database schema, security controls, and a fixed price quote. After you approve, we start building.
Everything that ships with your backend
No surprises. Here is exactly what you get when IRPR builds your backend.
We deliver a production-ready system, not just code. Every project includes infrastructure, monitoring, and documentation so your team can take over immediately.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code (Terraform or CloudFormation)
- Database schema and migration scripts
- API documentation (OpenAPI/Swagger)
- Sentry error tracking and CloudWatch dashboards
- Load test results (k6 or Artillery)
- Postman collection for manual testing
- Deployment runbook and environment setup guide
- 30-day post-release warranty
What we ship in this practice.
Payment processing API for fintech startup
Built a PCI-DSS compliant payment aggregation API using Node.js, Stripe Connect, and PostgreSQL. The system handles 1,000+ transactions per minute and reduced manual reconciliation by 15 hours per week.
Real-time chat backend for health app
Developed a WebSocket-based chat backend with end-to-end encryption using Socket.io, Redis, and MongoDB. Supports 50,000 concurrent connections with under 50ms latency.
Inventory management API for ecommerce brand
Created a RESTful inventory API with real-time stock sync across 3 warehouses. Uses Django, PostgreSQL, and Celery for async updates. Cut inventory errors by 90%.
User authentication service for SaaS platform
Implemented a multi-tenant auth system with OAuth2, SAML, and social login. Built with Go, Redis, and JWT. Handles 100,000 user registrations with 99.99% uptime.
Data processing pipeline for logistics company
Designed a serverless data pipeline on AWS Lambda and Kinesis that processes 10 million GPS coordinates per day. Reduced data processing cost by 60% compared to previous batch system.
Cloud migration of legacy PHP backend
Replaced a monolithic PHP backend with a microservices architecture on AWS ECS. Used Node.js and PostgreSQL. cut page load times from 4 seconds to 200ms and saved 40% on hosting costs.
Why teams hire us.
Fixed price, not hourly
Every backend project gets a fixed quote after the 2-week Roadmap phase. No hourly billing means no surprise invoices or scope creep. You know the cost before we write a line of code.
Senior engineers only
IRPR does not hire juniors. Every engineer has 10+ years of experience with Node.js, Python, Go, or Java. Your project is built by someone who has shipped similar backends before.
Full code ownership
You own 100% of the source code, infrastructure configs, and documentation. No licensing fees, no proprietary lock-in. Your team can take over on day one after launch.
Compliance built in from day one
We bake HIPAA, PCI-DSS, and SOC 2 controls into the architecture. For fintech clients, we implement tokenization and audit logging before the first API endpoint is written.
Async-first with daily overlap
IRPR works async-first with a global team, but every project has 4 hours of daily overlap with your US timezone. You get daily standup recordings and a Slack channel for real-time questions.
12-week delivery guarantee
We have delivered 200+ backend projects, 98% on time. If we exceed the agreed timeline, we discount the next phase by 10%. Our process is built for speed without cutting quality.
Idea → Roadmap → Product → Release.
