Expert Custom Backend Development Developers by the Numbers
Our track record shows what expert custom backend development developers deliver.
IRPR's backend developers have built production systems for 200+ products across 50 countries. 98% of projects launch on or before the scheduled date. Our average backend handles 10 million API calls per month with 99.9% uptime.
A typical backend project costs 80,000 to 250,000 dollars. We fix the price in week 2 after the Roadmap phase. Clients see a working backend in 8 to 12 weeks. Post-launch, we provide a 30 day warranty for any bug fixes.
What Makes Expert Custom Backend Development Developers Different
Not every agency delivers production-ready backend code. Here is what sets IRPR apart.
Generic dev shops hand off code that requires months of rework. They skip unit tests, ignore security, and leave you with a monolithic mess. You pay hourly and the scope never ends.
IRPR writes backend code that ships. We use automated CI/CD pipelines with GitHub Actions. Every pull request runs unit tests, integration tests, and security scans. Your team gets the code in your own repo from day one.
- No written test coverage
- No CI/CD pipeline
- Monolithic code with tight coupling
- No rate limiting or monitoring
- Hourly billing with no cap
- No compliance documentation
- 95%+ test coverage with Jest and pytest
- GitHub Actions CI/CD with automatic deploys
- Dockerized microservices or modular monolith
- Sentry + CloudWatch monitoring and alerts
- Fixed price quoted in week 2
- HIPAA / PCI / SOC 2 ready docs
Our Process for Expert Custom Backend Development
We follow a 4-phase process to build your backend with no surprises.
Each phase has a concrete deliverable. You see real code, real tests, and a real running backend by week 10. No wireframes. No mockups. Just a working API.
The process starts with a Roadmap phase where we define every endpoint, table, and third-party integration. We fix the price and timeline before any code is written.
What Ships with Expert Custom Backend Development Developers
Every backend project includes these deliverables by default.
You own everything we build. The code lives in your GitHub or GitLab repo from day one. No licensing fees. No lock-in. No hidden costs.
Our standard handoff package includes the running production backend, complete documentation, and a CI/CD pipeline that your team can use immediately.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking with alert rules
- CloudWatch dashboards for API latency and error rates
- Postman collection or OpenAPI spec for every endpoint
- Database schema migration scripts (Flyway or Alembic)
- Docker Compose file for local development
- Environment configuration for staging and production
- Load test results from k6 or Artillery
- 30 day post-launch warranty and Slack support
What we ship in this practice.
Real-time payment processing backend
Built a payment gateway backend using Go and PostgreSQL that processes 500 transactions per second. Integrated with Stripe and Plaid. Reduced settlement time from 3 days to 4 hours.
HIPAA-compliant telemedicine API

Multi-tenant SaaS backend for CRM
Built a Python FastAPI backend with per-tenant PostgreSQL schemas. Supports 500+ tenants with zero downtime during migrations. Reduced tenant onboarding time from 2 weeks to 2 hours.
Ecommerce order orchestration engine
Built an event-driven backend with RabbitMQ and Node.js that coordinates order placement, inventory deduction, and shipping label generation. Handles 50,000 orders per day. Reduced order processing time by 80%.
Real estate listing sync platform
Built a Python backend that syncs MLS listings to 3 major real estate portals every 5 minutes. Uses Redis caching to serve listing pages in under 200ms. Handles 2 million listing records.
Logistics route optimization API
Built a Go microservice that runs the Google OR-Tools solver to optimize delivery routes for 200+ drivers daily. Reduced fuel costs by 12% and on-time delivery rate rose to 98%.
Why teams hire us.
Senior engineers only, no juniors
Every developer at IRPR has 8+ years of backend experience. We do not hire junior developers or outsource to low-cost markets. You get a senior engineer who can architect, build, and deploy without handholding.
Fixed price quoted in week 2
After the Roadmap phase, we give you a fixed price for the entire project. No hourly billing. No surprises. If the scope changes, we write a change order with a new fixed price before we start the extra work.
Production code from day one
We do not build prototypes. Every line of code is written for production: automated tests, error handling, logging, and monitoring. Your backend is ready to handle real traffic from launch day.
Compliance built in
We have built backends that pass HIPAA, PCI-DSS, and SOC 2 audits. Our code includes encryption at rest and in transit, audit logs, and role-based access control. We generate compliance documentation as part of the build.
You own the code, full IP
All source code, documentation, and configuration files are yours. No licensing fees. No subscriptions. No hidden costs. You can deploy, modify, or hand off the code to your team anytime.
30 day post-launch warranty
After we deploy to production, we provide 30 days of free bug fixes. Your team gets direct Slack access to the developers who built the backend. No tickets, no queue, just a direct chat.
