Why companies choose IRPR for custom backend development
We ship production-ready backend systems in 8-12 weeks with a fixed price.
Our backend consultants have built over 200 products across 50+ countries. We use Node.js, Python, Go, and AWS to design systems that handle millions of requests per day.
Every project starts with a Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed quote before any engineering begins.
The difference between IRPR and generic backend consulting
Most agencies bill hourly and change scope. We don't.
Generic dev shops often start coding without a clear architecture. They use hourly billing, which leads to scope creep and budget overruns. Code quality varies, and documentation is sparse.
IRPR uses a fixed-price model after a 2-week Roadmap. We write tests, document APIs with OpenAPI, and set up CI/CD on day one. You own the code and the infrastructure.
- Hourly billing with no cap
- No architecture document upfront
- Inconsistent code quality
- Sparse or missing documentation
- No CI/CD pipeline
- No post-launch support plan
- Fixed price after Roadmap phase
- Detailed architecture and data model
- Code reviews and automated tests
- OpenAPI docs and README
- CI/CD on GitHub Actions
- Sentry monitoring and 99.9% uptime SLA
Our backend development process
From idea to production in 8-12 weeks.
We follow a four-phase process: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we deliver a full architecture document, data model, API contracts, and a fixed price.
During Product phase (weeks 3-10), we build in 2-week sprints with daily standups and weekly demos. Release phase includes load testing, security audit, and deployment.
What ships with every backend project
You get more than just code.
Every project includes source code in your private GitHub repo, a CI/CD pipeline using GitHub Actions, and infrastructure as code with Terraform. We also provide a deployment runbook and 30 days of post-launch support.
Our standard stack includes Node.js or Python, PostgreSQL, Redis, and AWS ECS. We set up error tracking with Sentry, logging with CloudWatch, and uptime monitoring.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Infrastructure as code (Terraform)
- API documentation (OpenAPI/Swagger)
- Automated tests (Jest, Pytest)
- Error tracking (Sentry)
- Logging (CloudWatch)
- Deployment runbook
- 30-day post-launch support
- Security audit summary
What we ship in this practice.
Real-time analytics dashboard for a SaaS startup
Built a Node.js backend with WebSocket and Redis to stream real-time metrics. The client reduced page load time from 3s to 200ms and scaled to 10k concurrent users. Tech: Node.js, Socket.io, Redis, PostgreSQL, AWS ECS.
Payment processing backend for a fintech app
Designed a PCI-DSS compliant payment system using Stripe Connect and a custom ledger in PostgreSQL. The client processed $5M in transactions in the first quarter with zero security incidents. Tech: Python, FastAPI, Stripe, PostgreSQL, AWS.
Telehealth platform backend with HIPAA compliance
Built a HIPAA-compliant backend for video consultations and scheduling. Used WebRTC, Twilio, and encrypted storage on AWS HealthLake. The client onboarded 500 providers in 6 weeks. Tech: Node.js, WebRTC, Twilio, AWS HealthLake, PostgreSQL.
Multi-tenant ecommerce backend for a marketplace
Created a scalable backend with separate databases per tenant and shared services for search and checkout. The client handled 1M monthly orders with 99.9% uptime. Tech: Go, PostgreSQL, Elasticsearch, Stripe, AWS.
Legacy migration backend for an enterprise
Migrated a monolith to microservices on Kubernetes. Reduced deployment time from 2 hours to 5 minutes and cut infrastructure costs by 40%. Tech: Node.js, Docker, Kubernetes, Terraform, AWS.
Content recommendation engine for a media platform
Built a collaborative filtering recommendation system using Python and TensorFlow Serving. Increased user engagement by 35% and reduced churn by 20%. Tech: Python, TensorFlow, Redis, PostgreSQL, AWS.
