Backend App Development AgencyApp Development
We build backend systems that ship in 8-12 weeks. Fixed pricing, senior engineers only, 200+ products delivered.
IRPR is a backend app development agency that builds server-side systems using Node.js, Python, Go, and Rust. We design APIs, databases, microservices, and cloud infrastructure for web and mobile apps.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance like HIPAA, PCI-DSS, and SOC 2. You get source code, CI/CD pipelines, and monitoring dashboards.
CTOs hire us when their in-house team is at capacity. Startup founders hire us to build their MVP and get to market fast. Product managers hire us to add backend features without hiring full-time engineers.
Types of software we ship.
REST API development
Build stateless RESTful APIs with Express.js or FastAPI. Supports rate limiting, caching with Redis, and OpenAPI docs.
GraphQL API development
Build GraphQL APIs with Apollo Server or Hasura. Single endpoint, strong typing, real-time subscriptions.
Microservices architecture
Design microservices with Docker and Kubernetes. Each service is isolated, scalable, and independently deployable.
Database design and optimization
Design relational databases with PostgreSQL or NoSQL with MongoDB. Includes indexing, query optimization, and migration scripts.
Real-time backend systems
Build WebSocket servers with Socket.io or real-time streams with Kafka. Used for chat, live notifications, and collaborative tools.
Serverless backend development
Build serverless functions on AWS Lambda or Google Cloud Functions. Pay per execution, auto-scale, no server management.
Third-party API integration
Integrate Stripe, Twilio, Salesforce, HubSpot, and other APIs. Handle OAuth, webhooks, and data sync.
Backend for AI applications
Build backend pipelines for AI models using FastAPI and Celery. Handle model inference, data preprocessing, and result storage.
We build for every business type.
SaaS platforms
ecommerce platforms
healthcare applications
fintech applications
enterprise applications
What We Build as a Backend App Development Agency
Every backend project includes API design, database setup, cloud deployment, and monitoring from day one.
When you hire IRPR as your backend app development agency, you get a full engineering team that writes production-ready code. We start with an API specification in OpenAPI 3.0 so everyone agrees on the contract. Then we build the database schema, write the business logic, and deploy to AWS or Google Cloud.
We include CI/CD pipelines using GitHub Actions or GitLab CI. Every pull request runs tests and linters. We set up Sentry for error tracking and Datadog for performance monitoring. Your backend is observable from day one.
The Difference Between IRPR and a Generic Dev Shop
Most agencies bill hourly and overpromise. IRPR gives you a fixed price and a real timeline.
Generic dev shops often start with a vague estimate and then charge more when requirements change. They hand off code with no documentation or monitoring. You end up with a backend that breaks in production and no one knows why.
IRPR writes tests, sets up monitoring, and documents every API endpoint. We give you a fixed price in the Roadmap phase (week 2). No surprise invoices. We also transfer full ownership of the code and infrastructure.
- Hourly billing with vague estimates
- No tests or CI/CD
- No monitoring or error tracking
- No documentation
- Code stays on their servers
- Slow communication across time zones
- Fixed price from week 2
- Automated tests with 90%+ coverage
- Sentry and Datadog from day one
- OpenAPI docs for every endpoint
- Full ownership of code and infra
- Async-first with daily standups
Our Process for Building Your Backend
Four phases from idea to production. Each phase has a clear deliverable and a fixed timeline.
We follow a structured process that IRPR has refined over 200+ projects. Every phase ends with a review and a go/no-go decision. You always know what comes next and how much it costs.
The process works for startups building an MVP and for enterprises adding a new backend service. We adapt the timeline based on your scope, but the phases stay the same.
What Ships with Every Backend Project
You get more than code. Every deliverable is designed to keep your backend running in production.
When IRPR completes your backend app development project, you receive a complete package. Not just source code, but everything needed to run, monitor, and maintain the system.
We also provide a handoff session where we walk your team through the architecture, the deployment process, and how to handle common issues. You are never left alone.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with automated tests
- API documentation in OpenAPI 3.0
- Database migration scripts
- Docker Compose files for local development
- Sentry error tracking integration
- Datadog performance dashboards
- Deployment runbook with rollback steps
- 30-day post-launch warranty
What we ship in this practice.
Telemedicine backend for a health startup
Built a HIPAA-compliant backend with Node.js and PostgreSQL. Handles video call scheduling, patient records, and insurance verification. Reduced appointment no-shows by 40% with automated reminders.
Payment processing backend for a fintech app
Built a PCI-DSS Level 1 compliant backend with Python and Stripe Connect. Processes 10,000+ transactions per day. Reduced chargeback rate to 0.2% with fraud detection rules.
Real-time inventory backend for a retail chain

SaaS backend for a project management tool
Built a multi-tenant backend with Ruby on Rails and PostgreSQL. Supports 5,000+ active teams with sub-second response times. Scaled to 50K users without downtime.
ML model serving backend for a logistics company
Built a FastAPI backend with Celery for async model inference. Processes 10,000 route optimization requests per hour. Reduced delivery times by 20% using predictive routing.
Content management backend for a media platform
Built a headless CMS backend with Node.js and GraphQL. Manages 1M+ articles with full-text search and image optimization. Cut page load times by 60% with CDN caching.
Why teams hire us.
Senior engineers only
Every engineer on your project has 7+ years of backend experience. No juniors, no offshore interns. You talk directly to the engineers building your system.
Fixed price, not hourly
We give you a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
8-12 week delivery
We ship production-ready backend systems in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects finish on time.
Full ownership of code and infra
You own all source code, Docker images, and cloud infrastructure. We transfer everything to your accounts at the end of the project. No lock-in, no license fees.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends. We include encryption at rest and in transit, access controls, and audit logging by default.
Production monitoring from day one
We set up Sentry, Datadog, and PagerDuty before we deploy. You get real-time alerts on errors, latency spikes, and downtime. No blind spots.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
