Custom Backend Development StudioDevelopment Studio
We build backend systems that scale to millions of users. Get a fixed price quote in week 2 of your project.
IRPR is a custom backend development studio that builds production-ready APIs, microservices, and cloud infrastructure. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to deliver systems that handle millions of requests per day.
Every project ships with source code in your repo, CI/CD pipelines, and monitoring. Our typical MVP takes 8-12 weeks and costs between $80K and $250K depending on complexity. We work under HIPAA, PCI-DSS, and SOC 2 compliance requirements.
Founders hire us when they need a scalable backend for their SaaS product. CTOs hire us to rebuild legacy monoliths into microservices. Product managers hire us to build custom APIs that integrate with Salesforce, Stripe, or HubSpot. Enterprise teams hire us for backend architecture design and cloud migration.

Why choose a custom backend development studio
Off-the-shelf backends break when your business grows. A custom backend scales with you.
Generic backend frameworks like Firebase or Supabase work for prototypes but hit limits at 10,000 concurrent users. IRPR builds custom backends on Node.js, Go, or Python that handle 100,000+ concurrent connections with sub-50ms response times. We design database schemas in PostgreSQL with proper indexing and partitioning from day one.
Our team has shipped 200+ backend systems across 50 countries. Every project includes load testing with k6, error tracking with Sentry, and uptime monitoring with Datadog. We write unit tests with Jest and integration tests with Supertest. Your backend ships with 90%+ test coverage.
Generic dev shop vs IRPR custom backend development studio
Most dev shops build backends that work today but break tomorrow. IRPR builds for scale from day one.
Generic dev shops often use a single framework for every project. They skip load testing, ignore database indexing, and deliver code without CI/CD. You end up with a backend that crashes under 500 concurrent users and takes weeks to fix.
IRPR treats every backend as a production system from week 1. We design for horizontal scaling, implement caching with Redis, and set up auto-scaling on AWS ECS or Kubernetes. Your backend handles traffic spikes without manual intervention.
- No load testing before launch
- Monolithic code with no separation of concerns
- No CI/CD pipeline
- No error tracking or monitoring
- No database indexing strategy
- No documentation or API specs
- Load testing with k6 from week 2
- Microservices or modular monolith with clear boundaries
- CI/CD on GitHub Actions with automated tests
- Sentry error tracking and Datadog monitoring
- PostgreSQL with proper indexing and partitioning
- OpenAPI specs and auto-generated docs
How we build your custom backend
Our process turns your idea into a production-ready backend in 8-12 weeks.
We start with a 2-week Roadmap phase where we define the architecture, choose the tech stack, and give you a fixed price. No hourly billing. No surprises. You get a detailed document with API endpoints, database schema, and deployment plan.
Then we build in 2-week sprints. You see working code every 14 days. We deploy to staging on AWS, run automated tests, and demo the backend to you. By week 8-12, your backend is production-ready with monitoring, logging, and auto-scaling.
What ships with your custom backend
Every backend project includes these deliverables by default.
You get more than just code. Every project ships with infrastructure, documentation, and monitoring. No hidden costs. No extra fees for deployment or testing.
Our standard delivery includes source code in your GitHub repo, CI/CD pipelines, automated tests, API documentation, and production monitoring. You can take the code to any team after we finish.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated unit tests with 90%+ coverage
- Integration tests for all API endpoints
- OpenAPI 3.0 specification for all APIs
- Docker Compose for local development
- Terraform or CloudFormation for infrastructure
- Sentry error tracking and Datadog monitoring
- Load test results from k6
- Deployment runbook and architecture diagram
What we ship in this practice.

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 exact cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of backend engineering experience. Every engineer has shipped production systems handling 1M+ requests per day. No junior developers, no offshore outsourcing.
You own the code
Full source code is delivered to your GitHub repo. No proprietary frameworks, no license fees, no lock-in. You can take the code to any team after we finish.
Production-ready from day one
Every backend ships with CI/CD, monitoring, error tracking, and load testing. We don't hand over code that works on your laptop. We hand over systems that run in production.
Compliance built in
We build backends that pass HIPAA, PCI-DSS, SOC 2, and FERPA audits. Our infrastructure uses encryption at rest and in transit, access controls, and audit logging by default.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our record is 6 weeks for a fintech payment API. You don't wait 6 months to launch.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
