Backend App Development DevelopersApp Development
We build production-ready backends in 8-12 weeks. Fixed price, no hourly billing, full ownership of the code.
IRPR builds backend systems for web apps, mobile apps, and APIs using Node.js, Python, Go, and serverless frameworks on AWS and GCP. Our senior engineers design scalable architectures that handle millions of requests per month.
Every backend project ships in 8-12 weeks with a fixed price between $80K and $250K. We include CI/CD pipelines, automated testing, and compliance for HIPAA, PCI-DSS, and SOC 2.
Founders hire us to build their MVP backend before raising a seed round. CTOs hire us to rebuild legacy monoliths into microservices. Product managers hire us to add API integrations with Stripe, Salesforce, or HubSpot.
Types of software we ship.
REST API backend
Stateless RESTful APIs built with Express.js or FastAPI. Includes Swagger docs, rate limiting, and JWT auth.
GraphQL backend
GraphQL backends using Apollo Server or Hasura. Supports real-time subscriptions and federation.
Serverless backend
Event-driven backends on AWS Lambda or Cloud Functions. Scales to zero when idle, handles spikes without manual tuning.
Microservices backend
Decoupled microservices with Docker and Kubernetes. Each service has its own database and CI/CD pipeline.
Real-time backend

SaaS backend
Multi-tenant backends with subscription billing via Stripe or Chargebee. Includes RBAC, audit logs, and usage tracking.
Data pipeline backend
Batch and streaming data pipelines using Apache Kafka, Airflow, and BigQuery. Processes terabytes of data per day.
We build for every business type.
SaaS companies
Ecommerce brands
Healthcare apps

Why backend app development developers matter
The backend is the engine of your app. A poorly built backend causes slow load times, security holes, and expensive rewrites.
IRPR's senior engineers have shipped over 200 backend systems across 50 countries. We use Node.js, Python, Go, and serverless frameworks to build backends that start fast and stay fast under load. Every project includes automated load testing, database indexing, and caching layers.
We also handle compliance from day one. For healthcare apps, we build HIPAA-compliant backends with BAA agreements. For fintech, we follow PCI-DSS Level 1 standards. For SaaS, we implement SOC 2 controls. This saves you months of retrofitting later.
How IRPR differs from other backend development shops
Most agencies bill hourly, change scope, and hand off messy code. IRPR does the opposite.
Generic dev shops often start coding without a clear architecture. They use junior engineers, skip testing, and deliver a backend that barely runs. Then they charge you for every bug fix.
IRPR assigns senior engineers only. We start with a Roadmap phase (week 2) that documents the full architecture, database schema, and API design. You approve the plan before we write a single line of code. The price is fixed, the timeline is fixed, and you own the code.
- Hourly billing with no cap
- Junior developers learning on your project
- No documented architecture upfront
- Manual deployment, frequent downtime
- No load testing until production breaks
- You don't own the code or IP
- Fixed price from week 2
- Senior engineers only (10+ years average)
- Roadmap phase with full architecture docs
- CI/CD pipeline with automated tests
- Load testing before launch
- Full code ownership, no IP restrictions
Our backend development process
We follow a four-phase process that de-risks your project from day one.
Every backend project starts with a 2-week Roadmap phase. During this phase, we audit your requirements, design the database schema, choose the tech stack, and produce a fixed-price proposal. You see the full plan before any development begins.
After the Roadmap, we move to Product phase: 8-12 weeks of iterative development with weekly demos. We ship a production-ready backend with CI/CD, monitoring, and documentation. Then we handle Release and ongoing support.
What ships with every backend project
You don't just get code. You get a complete production system.
IRPR delivers a fully operational backend with monitoring, documentation, and deployment pipelines. You can hand the project to your internal team or keep us for ongoing development.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Automated test suite (unit, integration, load)
- API documentation via Swagger or Postman
- Database schema with migrations and seed data
- Monitoring and alerting with Sentry and Datadog
- Docker containers for local development
- Deployment scripts for AWS, GCP, or Azure
- Security audit report (OWASP top 10)
What we ship in this practice.
SaaS analytics dashboard backend
Built a multi-tenant backend for a marketing analytics startup. Used Node.js, PostgreSQL, and Redis. Handles 10 million events per day with 200ms query response times. Reduced infrastructure costs by 40% compared to the previous provider.
Telemedicine platform backend
Developed a HIPAA-compliant backend for a telemedicine app. Used Python FastAPI, AWS RDS, and Twilio for video. Supports 500 concurrent consultations with end-to-end encryption. Passed HIPAA audit on first attempt.
Ecommerce payment gateway backend
Created a custom payment processing backend for an online retailer. Used Go, Stripe Connect, and PostgreSQL. Processes 50,000 transactions per month with 99.99% uptime. Reduced chargeback rate by 30% with fraud detection logic.
Real-time chat backend for social app
Built a WebSocket backend for a social networking app. Used Socket.io, Redis Pub/Sub, and MongoDB. Supports 100,000 concurrent connections with sub-100ms latency. Scaled to 1 million users within 6 months.
Fintech loan origination backend
Designed a PCI-DSS compliant backend for a lending platform. Used Node.js, AWS Lambda, and DynamoDB. Automates credit checks, document verification, and fund disbursement. Reduced loan approval time from 3 days to 15 minutes.
Logistics tracking system backend
Built a real-time tracking backend for a logistics company. Used Python, Apache Kafka, and BigQuery. Processes 1 million tracking events per hour. Reduced delivery delays by 25% through predictive analytics.
Why teams hire us.
Fixed price, not hourly
Every backend 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 code.
Senior engineers only
Our team averages 10+ years of backend experience. We don't use junior developers or offshore contractors. Every engineer has shipped production systems at scale.
Architecture-first approach
We design the full architecture before any code is written. You get a documented database schema, API contract, and infrastructure plan. This prevents rewrites and technical debt.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends from day one. Our engineers know the audit requirements and implement controls during development, not after.
Full code ownership
You own every line of code we write. There are no licensing fees, no hidden IP clauses, no vendor lock-in. You can deploy the backend anywhere, anytime.
Production-ready from launch
Every backend ships with CI/CD, monitoring, load testing, and security hardening. You don't get a prototype. You get a system that handles real users on day one.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
