Expert Backend App Development FirmBackend App
We build backend systems that handle millions of requests. 200+ products shipped with 98% on-time delivery.
IRPR is an expert backend app development firm. We build server-side systems using Node.js, Python, Go, PostgreSQL, Redis, and AWS. Every project starts with a clear architecture plan.
We ship production-ready backend apps in 8-12 weeks. Pricing is fixed from $80K to $250K depending on complexity. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
CTOs hire us when their in-house team lacks backend depth. Startup founders hire us to build their first scalable API. Enterprise teams hire us to modernize legacy backend systems. Product managers hire us to ship a backend MVP on a fixed deadline.
Types of software we ship.
REST API development

Why you need an expert backend app development firm
A weak backend breaks your product. Here is what IRPR delivers.
IRPR has shipped 200+ backend systems across 50 countries. Our engineers average 10+ years of experience. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS as our core stack. Every project includes automated testing, CI/CD pipelines, and monitoring with Sentry and Datadog.
We start with a 2-week Roadmap phase. You get a fixed price, a detailed architecture diagram, and a delivery timeline. No surprises. No scope creep. We have maintained 98% on-time delivery across all projects.
Generic dev shop vs expert backend app development firm
Not all development teams build backend systems the same way.
Generic shops treat backend as an afterthought. They write code that works on a laptop but fails under load. IRPR designs for scale from day one.
We use load testing with k6, database indexing strategies, and caching layers with Redis. Every API endpoint is documented with OpenAPI. Every deployment uses infrastructure as code with Terraform.
- No dedicated backend architect
- Monolithic code from day one
- No load testing before launch
- Manual deployments
- No monitoring or alerting
- Hourly billing with scope creep
- Senior backend engineers only
- Microservices or modular monolith based on needs
- Load testing with k6 in the Roadmap phase
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and Datadog dashboards
- Fixed price from the Roadmap phase
How IRPR builds your backend app
Four phases from idea to production.
Every project follows the same proven process. It starts with a 2-week Roadmap where we define the architecture, data model, and API contracts. Then we build in 2-week sprints with demos every Friday.
You see working code from week 3. We deploy to a staging environment by week 6. Production launch happens by week 12. Post-launch we provide 30 days of warranty support.
What ships with every backend project
You own everything. No black boxes.
Every project delivers a complete, production-ready backend. You get the source code, infrastructure scripts, and documentation. There are no ongoing license fees or vendor lock-in.
We use open-source tools and standard cloud services. You can take the code to any team after we finish. We also provide a handoff session to walk your team through the system.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code with Terraform or Pulumi
- API documentation with OpenAPI/Swagger
- Automated test suite with Jest or Pytest
- Sentry error tracking and Datadog monitoring
- Database migration scripts
- Deployment runbook and architecture diagram
- 30-day post-launch warranty support
What we ship in this practice.
Telemedicine platform backend
Built a HIPAA-compliant backend for a telemedicine startup. Handles 10,000+ video consultations per month. Uses Node.js, PostgreSQL, and Twilio Video. Reduced patient wait time by 40%.
Payment processing API for fintech

Multi-tenant ecommerce backend
Built a multi-tenant backend for a B2B marketplace. Supports 500+ sellers with separate databases. Uses Node.js, PostgreSQL with row-level security, and Elasticsearch for search. Reduced page load time by 60%.
SaaS subscription management backend
Developed a subscription billing engine for a SaaS company. Handles 50,000+ active subscriptions. Uses Go, Stripe Billing, and RabbitMQ for async invoice generation. Reduced billing errors by 90%.
Real-time logistics tracking system
Built a real-time tracking backend for a logistics firm. Processes 1 million GPS pings per day. Uses Node.js, WebSockets, and MongoDB. Reduced delivery delays by 25%.
IoT data pipeline for manufacturing
Designed a data ingestion pipeline for a manufacturing plant. Handles 10,000 sensor readings per second. Uses Python, Kafka, and TimescaleDB. Enabled predictive maintenance, reducing downtime by 30%.
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 before we write a line of code.
Senior engineers only
Every engineer on your project has 10+ years of experience. No junior developers. No offshore teams. You work directly with the people building your system.
8-12 week MVPs
We ship production-ready backend apps in 8-12 weeks. Our record is 6 weeks for a fintech API. You get a working system fast, not a prototype.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant systems from day one. No retrofitting. No audit surprises. We have passed 10+ third-party security audits.
Full code ownership
You own all source code, infrastructure scripts, and documentation. No proprietary frameworks. No license fees. You can take the code to any team after we finish.
Post-launch support included
Every project includes 30 days of post-launch warranty support. We fix bugs, optimize queries, and hand over the system. You are never left alone after launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
