Professional Custom Backend Development FirmBackend Development
We build production-grade backends for 200+ products across 50 countries. Fixed pricing, senior engineers, and a clear 8-12 week timeline.
IRPR is a professional custom backend development firm that builds server-side architecture for web apps, mobile apps, and SaaS products. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS to create APIs, microservices, and data pipelines that scale to millions of requests.
Every project ships with a fixed price determined in the Roadmap phase (week 2). Typical budgets range from $80K to $250K for a production-grade backend in 8-12 weeks. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box.
Founders hire us when they need a backend that handles complex business logic without rewrites. CTOs hire us when their in-house team lacks bandwidth for a critical backend module. Enterprise architects hire us to build custom integrations between legacy systems and modern APIs.

Why hire a professional custom backend development firm
A generic dev shop builds what you ask. A professional firm builds what you need.
IRPR has shipped 200+ backends for startups and enterprises across 50 countries. Our senior engineers average 10+ years of experience. We use Node.js, Python, Go, PostgreSQL, Redis, and AWS as our primary stack, but we adapt to your existing infrastructure. Every project starts with a 2-week Roadmap phase where we define the architecture, data model, API contracts, and deployment plan before writing a single line of production code.
We do not outsource. Every line of code is written by IRPR engineers working in US time zone overlap hours. We deploy to AWS, GCP, or Azure with CI/CD pipelines on GitHub Actions. You get full ownership of the source code, documentation, and infrastructure as code. No black boxes, no vendor lock-in.
The difference between IRPR and a generic dev shop
Most backend development firms sell you hours. IRPR sells you outcomes.
A generic dev shop assigns junior developers, charges hourly, and delivers code that works in staging but fails under load. You end up paying for rewrites, missed deadlines, and technical debt. IRPR takes a different approach: fixed price, senior engineers only, and a proven 4-phase process from idea to release.
We guarantee the backend handles production traffic from day one. Every project includes load testing, error monitoring with Sentry, and a rollback strategy. Our engineers stay on call for 30 days after launch to ensure stability.
- Junior or mid-level engineers
- Hourly billing with no cap
- No architecture review
- No load testing before launch
- No compliance documentation
- You own spaghetti code
- Senior engineers only (10+ yrs avg)
- Fixed price from Roadmap phase
- Architecture review in week 2
- Load testing to 10x expected traffic
- HIPAA, PCI-DSS, SOC 2 compliance built in
- You own clean, documented, production-ready code
How IRPR builds your custom backend
A repeatable 4-phase process that eliminates guesswork.
Every backend project at IRPR follows the same framework: Idea, Roadmap, Product, Release. This is not a sales pitch. It is a repeatable system that has delivered 200+ production backends on time and on budget.
In the Roadmap phase, we produce a detailed architecture document, a data model, API specifications, a deployment plan, and a fixed price quote. You approve the Roadmap before we write a single line of production code. No surprises.
What ships with every custom backend
You get more than code. You get a production-ready system.
Every backend project includes infrastructure as code, CI/CD pipelines, monitoring, and documentation. You can deploy to any cloud provider without needing IRPR. The code is yours, the docs are yours, the infrastructure is yours.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure as code (Terraform or Pulumi)
- API documentation (OpenAPI 3.0)
- Load test results and performance benchmarks
- Sentry error tracking configured
- CloudWatch or Datadog monitoring dashboards
- Deployment runbook with rollback steps
- 30-day post-launch support and on-call
