Expert Scalable Backend Development ConsultantsScalable Backend
We build backend systems that handle millions of requests without breaking. 200+ products shipped, 50+ countries, fixed pricing from $80K.
IRPR is a team of senior backend engineers who design and build scalable backend systems. We use Node.js, Python, Go, PostgreSQL, Redis, Kafka, and cloud infrastructure on AWS, GCP, or Azure to handle high traffic, complex data pipelines, and real-time processing.
We ship production-ready backend code in 8-12 weeks for MVPs, with fixed pricing from $80K to $250K. Every project includes load testing, CI/CD pipelines, monitoring with Datadog or Sentry, and compliance with HIPAA, PCI-DSS, or SOC 2 as needed.
Our clients are CTOs at Series A startups who need a backend that scales to 1M users, engineering leads at mid-market companies migrating from monoliths to microservices, and product owners at enterprises building internal APIs for 10,000+ employees.
Types of software we ship.

Why hire expert scalable backend development consultants
A poorly designed backend costs you users, revenue, and engineering time. Here is what IRPR delivers.
We have shipped 200+ backend systems across 50 countries. Our engineers average 10+ years of experience in distributed systems, cloud infrastructure, and high-performance databases. Every project starts with a Roadmap phase where we define the architecture, data model, and API contracts before writing a single line of code.
We use load testing tools like k6 and Artillery to validate that your backend handles 10x your expected traffic. We set up monitoring with Datadog, Sentry, and PagerDuty so you see errors before your users do. And we write integration tests that cover 90%+ of critical paths.
Generic dev shops vs expert scalable backend development consultants
Not all backend consultants are the same. Here is how IRPR differs from a generic agency.
Generic shops often deliver a monolithic Node.js app with no tests, no CI/CD, and no monitoring. They hand you a zip file and disappear. IRPR delivers a production-grade backend with automated deployments, error tracking, and a 99.9% uptime guarantee.
We also handle compliance. If you need HIPAA, PCI-DSS, or SOC 2, we build the backend with encryption at rest and in transit, audit logs, and access controls from day one. No retrofitting.
- Monolithic architecture with no scaling plan
- No load testing or performance benchmarks
- No CI/CD pipeline - manual deploys
- No monitoring or alerting
- No documentation or API specs
- Hourly billing with scope creep
- Microservices or modular monolith with auto-scaling
- Load tested with k6 to handle 10x traffic
- CI/CD with GitHub Actions, Docker, and Kubernetes
- Monitoring with Datadog, Sentry, and PagerDuty
- OpenAPI specs and architecture diagrams
- Fixed price from $80K with no surprises
Our process for building scalable backends
We follow a 4-phase process that de-risks your project from day one.
Phase 1 is the Roadmap. In 2 weeks we define the architecture, data model, API contracts, and infrastructure plan. You get a fixed price quote and a timeline. No code is written until you approve the plan.
Phase 2 is the Build. We develop the backend in 6-8 weeks with daily commits, automated tests, and weekly demos. Phase 3 is the Release - we deploy to production with blue-green deployments and rollback plans. Phase 4 is the Handoff - you get full source code, CI/CD pipelines, and documentation.
What ships with every backend project
Every backend we build includes these deliverables by default.
We do not hand over a zip file. You get a fully operational system with everything needed to run, monitor, and extend it. All code is in your repository from day one.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker containers and docker-compose for local dev
- Kubernetes manifests or Terraform for cloud infra
- OpenAPI 3.0 specification for all endpoints
- Integration tests with 90%+ coverage on critical paths
- Monitoring dashboard with Datadog or Grafana
- Error tracking with Sentry
- Load test results from k6 or Artillery
- Architecture diagram and deployment runbook
What we ship in this practice.
Multi-tenant SaaS backend for a B2B analytics platform
Built a multi-tenant backend with PostgreSQL row-level security, Redis caching, and a GraphQL API. Handles 500 concurrent tenants with sub-200ms response times. Reduced infrastructure costs by 40% compared to the previous single-tenant setup. Tech stack: Node.js, PostgreSQL, Redis, Apollo GraphQL, AWS ECS.
Real-time order processing backend for a food delivery app
Designed an event-driven backend with Kafka for order processing and WebSockets for real-time driver tracking. Processes 10,000 orders per hour with 99.95% uptime. Reduced order-to-delivery time by 25%. Tech stack: Go, Kafka, PostgreSQL, Socket.io, GCP Kubernetes.
HIPAA-compliant backend for a telehealth platform

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. You know the cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of backend experience. No junior developers. Every engineer has shipped production systems handling millions of requests per day.
Production-grade from day one
We ship with CI/CD, monitoring, error tracking, and load testing. Your backend is production-ready from the first deployment, not a prototype that needs months of hardening.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends from the start. No retrofitting. We handle encryption, audit logs, and access controls as part of the architecture.
Full ownership, no lock-in
You own all source code, infrastructure configs, and documentation. No proprietary frameworks. No recurring fees. You can take the system to any team after we hand it off.
Fast start, faster delivery
We kick off within 1-2 weeks of signing. Most MVPs ship in 8-12 weeks. We use proven patterns and libraries so we do not reinvent the wheel.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
