Professional Custom Backend Development StudioBackend Development
We build custom backend systems for your product. Senior engineers, fixed pricing, 12-week delivery.
IRPR is a professional custom backend development studio that builds server-side systems for startups and enterprises. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS services like Lambda and ECS to create scalable backends.
Each project ships within 12 weeks on average, with fixed prices from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance, so your backend meets regulatory standards from day one.
Clients hire us for professional custom backend development: founders launching a new product, CTOs migrating legacy systems, product managers needing a scalable API, and enterprise leaders facing performance bottlenecks.

Why professional custom backend development matters
A custom backend gives you control over performance, security, and scalability.
Off-the-shelf backends often hit limits as your user base grows. With a custom backend, you own the architecture and can optimize every query. IRPR has built 200+ backends that handle millions of requests per day.
Performance directly impacts user retention: a 1-second delay can reduce conversions by 7%. Our backends use caching, database indexing, and async processing to keep latency under 50ms.
The difference between generic dev shops and IRPR
Not all backend teams deliver the same quality. Here is what sets IRPR apart.
Many agencies sell backend development but lack deep infrastructure experience. They rely on junior developers or outsource work, leading to fragile systems and missed deadlines. Compliance knowledge is often an afterthought.
IRPR is a professional custom backend development studio with senior engineers only. Every project includes a fixed price, a 12-week timeline, and full compliance support. We have shipped 200+ backends across fintech, healthcare, and SaaS.
- Hourly billing that leads to cost overruns
- No HIPAA or PCI compliance knowledge
- Slow email responses (3+ days)
- Junior developers on your project
- No fixed delivery timeline
- Code ownership often unclear
- Fixed price from $80K to $250K per project
- HIPAA, PCI-DSS, and SOC 2 compliant
- One business day response time
- Senior engineers with 10+ years experience
- Guaranteed 12-week delivery
- 100% code ownership in your repository
Our backend development process
From idea to deployment, we follow a clear, repeatable process.
Every backend project starts with a Roadmap phase. You get a detailed architecture document, a fixed quote, and a timeline before we write a single line of code. No surprises.
Development happens in weekly sprints with continuous deployment. You see progress every week, not just at the end. We use automated tests and code reviews to maintain quality.
What ships with every custom backend
You get more than just code.
Every backend project includes production-ready infrastructure, documentation, and monitoring. You will have everything needed to run, maintain, and scale your system.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error monitoring and alerts
- Infrastructure as code (Terraform) for AWS
- API documentation with Swagger or Postman
- Load testing results and performance report
- Security scan report with OWASP checks
- Admin dashboard with management endpoints
- Deployment runbooks and on-call setup
- 30 days of post-launch support
What we ship in this practice.
Real-time analytics dashboard
