Professional Backend App Development FirmApp Development
We build production-grade backend systems for startups and enterprises. Get an MVP in 8 to 12 weeks with a fixed price.
IRPR builds backend systems using Node.js, Go, Python, PostgreSQL, and AWS. We design APIs that handle thousands of requests per second with 99.9% uptime.
We ship production-ready endpoints, databases, and infrastructure in 8 to 12 weeks at fixed prices from $80K to $250K. Every project includes CI/CD, monitoring, and automated tests.
We work with CTOs scaling a SaaS platform, founders launching an MVP in a regulated industry, and enterprise teams migrating monolithic apps to microservices. Each client gets senior engineers only.
Types of software we ship.
RESTful API development
Design and implement REST APIs with Swagger docs, rate limiting, and JWT authentication. We use Express.js or Fastify.
GraphQL API development
Build GraphQL APIs with Apollo Server, data loaders, and subscription support for real-time features.
Microservices architecture
Decompose monoliths into Dockerized microservices with RabbitMQ or Kafka for async communication.
Real-time data pipeline
Stream data using Apache Kafka, Redis Streams, or AWS Kinesis. Process millions of events per day.
Backend for mobile apps
Provide push notifications, user sessions, and file uploads for iOS/Android. We use Firebase Cloud Messaging and S3.
Serverless backend
Deploy functions on AWS Lambda with API Gateway. Auto-scale to zero with no idle cost.
Database design and optimization
Design normalized schemas, set up indexes, and implement caching with Redis. We support Postgres and MongoDB.
Third-party integration backend
Connect to Stripe, Twilio, Salesforce, or HubSpot. Build webhook processors and OAuth flows.
We build for every business type.

Backend systems that scale from day one
Our professional backend app development firm has shipped 200+ systems across 50+ countries.
We use horizontal scaling patterns from the start: load balancers, read replicas, and caching layers. One client's backend handled a 10x traffic spike within 2 minutes with zero downtime.
Every system includes monitoring with Datadog, error tracking with Sentry, and automated rollbacks. We guarantee 99.9% uptime for production deployments.
How we differ from a generic dev shop
Most agencies assign junior developers and charge hourly. We do the opposite.
A typical dev shop might take 6 months to deliver an MVP with unpredictable costs. We deliver in 8 to 12 weeks with a fixed price determined in week 2.
Our senior engineers average 10+ years of experience. They write code that passes security audits and handles production traffic from day one.
- Hourly billing with no cap
- Junior developers assigned
- Vague timelines that slip
- No monitoring or CI/CD included
- Code ownership unclear
- Slow communication across time zones
- Fixed price set in week 2
- Senior engineers only (10+ years)
- 8-12 week MVP delivery
- CI/CD, Sentry, Datadog included
- Full code ownership
- Async-first with daily overlap
Our 4-phase process for building your backend
We move from idea to production release in 4 clear phases.
Every project starts with a 2-week Roadmap phase where we define architecture, choose tech stack, and lock the fixed price. No coding happens until you approve the plan.
We then build the MVP in 6-10 weeks, followed by a 1-week hardening phase for testing and documentation. The final release includes a 30-day warranty.
Everything that ships with your backend project
You get more than just code. Every deliverable is production-ready.
We include the full stack of tools and documentation so your team can operate the system without us.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerized microservices with docker-compose
- API documentation with Swagger/OpenAPI
- Sentry error tracking and alerting
- Datadog monitoring dashboards
- Load test results with k6
- Security audit report (OWASP top 10)
- Deployment runbook and architecture diagram
- 30-day warranty on all code
What we ship in this practice.
Real-time notification system for logistics platform
Built a WebSocket-based backend using Go, Redis, and AWS Fargate. Reduced notification delivery time from 30 seconds to under 1 second. Handles 500K events per day.
HIPAA-compliant patient data API for telehealth
Developed a FHIR-compliant backend with Node.js, PostgreSQL, and BAA with AWS. Passed HIPAA audit in 3 weeks. Enabled integration with 3 EHR systems.
Multi-tenant backend for B2B SaaS platform
Created a tenant isolation system using Postgres row-level security and Redis rate limiting. Supported 200 tenants at launch with zero data leaks.
Order management backend for ecommerce brand
Built REST APIs with Python, Django, and Stripe integration. Reduced order processing time by 60%. Handled 1M orders in first month.
Serverless image processing pipeline for media platform
Used AWS Lambda, S3, and Sharp to resize and optimize images. Reduced CDN bandwidth cost by 40% and served 2M images per day.
Financial data aggregation API for fintech startup
Built a GraphQL backend with Go, Kafka, and TimescaleDB. Aggregated data from 5 bank APIs with 99.95% uptime. Achieved SEC compliance.
Why teams hire us.
Fixed price, not hourly
Every 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 upfront.
Senior engineers only
We do not hire juniors. Every engineer on your project has 10+ years of experience and has shipped production systems handling millions of users.
Full code ownership
You own all source code, documentation, and infrastructure configs. We transfer everything to your Git repo and AWS account. No lock-in.
Production-ready from day one
Your backend ships with CI/CD, monitoring, error tracking, and load testing. It is ready for real traffic the moment we hand it over.
Post-launch support included
We include 30 days of support after release. Critical bugs are fixed within 4 hours. Extended support is available at a fixed monthly fee.
Compliance built in
We design for HIPAA, PCI-DSS, SOC 2, and FERPA from the start. One client passed their audit without a single finding due to our architecture choices.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
