Why you need experienced backend consultants
Building backend infrastructure is complex and risky without the right experience.
A poorly architected backend leads to spiralling maintenance costs and downtime. IRPR engineers have built systems that handle millions of requests per day.
We design for scale from day one. Our backends use microservices, caching layers, and async processing to keep performance consistent as you grow.
The difference between generic dev shops and IRPR
Not all developers architect backends the same way. Here is what sets IRPR apart.
Generic shops often deliver monolithic code with no documentation. You inherit technical debt from day one.
IRPR builds modular, testable backends with CI/CD pipelines and monitoring from the start. Every system is designed to evolve.
- No architecture planning
- Tight coupling between services
- No CI/CD pipeline
- Monolithic codebase
- No monitoring or alerts
- Scope creep and hourly billing
- Architecture-first design
- Microservices by default
- CI/CD from day one
- Modular and testable code
- Sentry + Datadog monitoring
- Fixed price, no surprises
Our backend development process
We follow a structured 4-phase process to deliver reliable systems.
Every project starts with a Roadmap phase where we define scope, architecture, and fixed price. This takes 1-2 weeks.
Then we build the backend in sprints, with weekly demos. You see progress every week, no black boxes.
What ships with every backend project
Every project comes with these deliverables by default.
You own everything. No vendor lock-in, no black boxes.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Infrastructure as code (Terraform)
- API documentation (Swagger/OpenAPI)
- Unit and integration tests
- Deployment runbook
- Sentry error tracking
- Datadog monitoring dashboard
- Postman collection
- Security audit report
What we ship in this practice.
Real-time analytics dashboard for fintech
Built a real-time analytics backend using Node.js, Kafka, and PostgreSQL. Reduced data processing latency from minutes to under 2 seconds. Handles 10,000 events per second.
Telemedicine platform backend
Developed a HIPAA-compliant backend for a telemedicine startup using Python, Twilio Video, and PostgreSQL. Enabled secure video consultations and EHR integration. Reduced patient wait time by 40%.
Payment processing service for ecommerce
Created a PCI-DSS compliant payment backend using Go, Stripe, and AWS Fargate. Processes 50,000 transactions per day with 99.99% uptime. Cut transaction fees by 15% through custom routing.

Data pipeline for logistics company
Designed a real-time data pipeline using Apache Kafka, Python, and Amazon Redshift. Processes GPS tracking data from 5,000 vehicles and reduces route calculation time from 5 minutes to 15 seconds.
Authentication service for SaaS platform
Developed an OAuth 2.0 authentication service using Node.js, Passport.js, and PostgreSQL. Supports SSO with Google, Microsoft, and Okta. Used by 10 enterprise clients with 50,000 users.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing means no surprise invoices. You know the cost before we write a line of code.
Senior engineers only
Our team consists of engineers with 10+ years of experience. We assign a lead architect to every project to ensure quality and consistency.
Architecture-first approach
We design the system architecture before coding. This prevents technical debt and ensures scalability. Every backend includes a documented architecture diagram.
8-12 week delivery
We ship production-ready backends in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of projects finish on time.
Full ownership of code
You own 100% of the source code, infrastructure scripts, and documentation. IRPR never uses proprietary frameworks or licenses.
Post-launch support
We include 2 weeks of post-launch monitoring and support. Our team remains available for maintenance and feature additions after the project ends.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
