Why top custom backend development developers choose IRPR
We build backends that handle millions of requests without breaking a sweat.
IRPR has delivered over 200 custom backends for startups and enterprises across 50 countries. Our senior engineers average 12 years of experience, so you get production-grade code from the first sprint.
Every backend ships with automated testing, CI/CD, and monitoring built in. We maintain a 98% on-time delivery rate and guarantee 99.9% uptime for all production deployments.
The difference between generic backend shops and IRPR
Not all development teams deliver enterprise-grade backend code.
Many agencies rely on junior-heavy teams and hourly billing that spirals out of control. Documentation is often an afterthought, and compliance expertise is rare.
IRPR flips the model: senior engineers only, fixed price from the start, and comprehensive API docs included. We handle compliance certifications like SOC 2, HIPAA, and PCI-DSS natively.
- Junior-heavy teams
- No fixed pricing
- Poor documentation
- No compliance experience
- Slow response times
- Code ownership unclear
- Senior engineers only (10+ years)
- Fixed price from Roadmap phase
- Comprehensive API docs (Swagger)
- SOC 2 / HIPAA / PCI experience
- 48-hour bug fix SLA
- Full source code ownership
How we build your custom backend in 4 phases
Our process from idea to production.
We start with a 2-week Roadmap phase to define scope, architecture, and a fixed price. No code is written until you approve the plan.
Then we design, build, and launch iteratively. You see working software every week, and we deploy to production only after passing all security and performance checks.
What ships with your backend
Every delivery is production-ready from day one.
IRPR doesn't just hand over code. You get the full toolchain to run, monitor, and scale your backend independently.
- Source code in your repo
- CI/CD pipeline on GitHub Actions
- Automated test suite (unit + integration)
- API documentation (Swagger/OpenAPI)
- Docker Compose for local dev
- Sentry error tracking
- Datadog monitoring dashboard
- Infrastructure as code (Terraform)
- Security scanning (Snyk)
- 99.9% uptime guarantee
What we ship in this practice.
SaaS billing backend
Built a subscription billing system for a SaaS company using Node.js, Stripe, and PostgreSQL. Reduced churn by 15% by automating dunning workflows.
Real-time analytics pipeline
Architected a streaming data pipeline for an e-commerce client using Kafka, Flink, and ClickHouse. Cut reporting latency from 2 hours to 30 seconds.
HIPAA-compliant patient portal
Developed a secure backend for a telehealth startup using TypeScript, FHIR APIs, and AWS. Achieved HIPAA compliance in 10 weeks.
Payment processing gateway
Designed a PCI-DSS compliant payment API for a fintech platform using Python, FastAPI, and Stripe Connect. Processed over $10M in transactions in the first month.
Multi-tenant collaboration backend
Built a real-time collaboration backend for a project management tool using WebSockets, Redis, and MongoDB. Handled 50,000 concurrent users on launch.
Inventory management API
Created a scalable inventory service for a retail chain using Go, gRPC, and PostgreSQL. Reduced inventory reconciliation time by 80%.
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.
Senior engineers only
Our team averages 12 years of backend experience. No junior developers, no offshore outsourcing.
Full code ownership
You own every line of code we write. No black boxes, no locked-in licenses, no monthly fees for the codebase.
Compliance built in
We embed HIPAA, SOC 2, and PCI-DSS controls from day one. No costly retroactive audits.
Production-grade from week 1
Your backend runs on cloud infrastructure with monitoring, logging, and alerting from the first deployment. We don't wait until the end to make it stable.
48-hour bug fix SLA
After launch, we guarantee a response to critical bugs within 48 hours. We've maintained a 98% on-time delivery rate across 200+ projects.
Idea → Roadmap → Product → Release.
