We build backend systems that handle millions of requests without breaking. 200+ products shipped, 12 week average timeline, fixed price from day one.
IRPR builds highly scalable backend systems using Node.js, Go, PostgreSQL, Redis, and cloud-native services from AWS and GCP. We focus on event-driven architectures, microservices, and GraphQL APIs that stay fast under load.
Every project delivers a fully tested, production-ready backend in 8 to 12 weeks. Pricing is fixed from the Roadmap phase ($80K-$250K). We include load testing, CI/CD pipelines, and monitoring as standard.
CTOs at Series A startups hire us when their Node.js monolith starts timing out. Product owners at mid-market SaaS companies hire us to rebuild legacy Java backends. Tech founders in fintech and healthcare hire us to meet PCI-DSS and HIPAA compliance at scale.

Why You Need Scalable Backend Developers
A backend that works for 100 users today will fail at 10,000 users next month without proper architecture.
IRPR builds backends with horizontal scaling baked in from day one. We use stateless services, database connection pooling, and async task queues so your system grows without rewrites. Our Node.js and Go services run on AWS ECS or Kubernetes with auto-scaling policies that trigger at 60% CPU.
Clients who skip scalable architecture spend 3x more on emergency fixes during their first growth spike. We load test every endpoint to 5x projected traffic using k6 and Artillery. We also implement caching layers with Redis and CDN edge caching to keep latency under 200ms globally.
IRPR vs Generic Dev Shops for Backend
Most backend projects fail because of vague requirements and no load testing.
A generic shop writes code until you run out of budget. You get a monolith that crashes under 500 concurrent users. No API documentation, no monitoring, no scaling plan. You own the code but cannot deploy it safely.
IRPR delivers a production-grade backend with a fixed price and timeline. Every project includes horizontal scaling, load testing to 5x traffic, full API docs (Swagger), and a monitoring stack with Sentry and Datadog. We write code once that works for years.
- Hourly billing with no ceiling
- Monolithic architecture by default
- No load testing until go live
- No monitoring or alerting
- Vendor lock-in on cloud services
- Zero horizontal scaling support
- Fixed price from Roadmap phase
- Event-driven or microservice architecture
- Load tested to 5x projected traffic
- Sentry + Datadog monitoring by default
- Cloud-agnostic (AWS, GCP, Azure)
- Auto-scaling from day one
How We Build Scalable Backends
Our process takes you from idea to deployed backend in 4 phases over 8-12 weeks.
Phase 1 is the Roadmap (Week 1-2). We define every API endpoint, database schema, and scaling target. You get a fixed price and timeline before any code is written. Phase 2 is Core Build (Week 3-6). We build authentication, database models, and core APIs with load testing from sprint one.
Phase 3 is Integration (Week 7-8). We connect your backend to Stripe, SendGrid, Redis, or any third-party service. Phase 4 is Release (Week 9-12). We deploy to production, set up CI/CD on GitHub Actions, and run a 48-hour load test at 5x traffic. You own the code and the infrastructure.
What Ships With Every Backend
Every backend project includes these 9 deliverables by default.
When you hire IRPR as your best scalable backend development developers, you get more than code. Every project includes a CI/CD pipeline, monitoring, and production support for 30 days after launch.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- API documentation via Swagger/OpenAPI 3.0
- Database schema with migrations (Alembic or Knex)
- Load testing report with k6 or Artillery results
- Monitoring stack with Sentry and Datadog
- Cloud infrastructure as code (Terraform or Pulumi)
- Auto-scaling configuration for 5x traffic
- 30-day production support with 4-hour SLA
What we ship in this practice.
Ecommerce Order Processing Backend
Built a stateless order processing service for a D2C brand handling 15,000 orders/day. Used Node.js, PostgreSQL, BullMQ for async order fulfillment. Reduced order processing time from 4 seconds to 200ms. Achieved 100% uptime during Black Friday with 50,000 orders/hour.
Healthcare Patient Portal API
Developed a HIPAA-compliant FHIR API for a telemedicine startup. Used Go, PostgreSQL with encrypted columns, and Auth0 for SMART on FHIR auth. Handles 500,000 patient record queries per day with 150ms average latency.
Fintech Payment Ledger Service
Created a double-entry ledger system for a payments company. Used PostgreSQL with serializable isolation, Redis for rate limiting, and Stripe Connect for payouts. Processes 10,000 transactions per second with full audit logging.
Real-Time Analytics Pipeline
Built a Kafka-based streaming pipeline for a marketing analytics platform. Used Kafka Streams, ClickHouse for storage, and Node.js for ingestion. Reduced data processing latency from 5 minutes to 2 seconds. Handles 1 million events per minute.
SaaS Multi-Tenant Platform
Scoped and rebuilt a multi-tenant SaaS backend from a monolithic PHP app to microservices on AWS ECS with Go. Used DynamoDB for tenant isolation and Redis for session caching. Cut cost per tenant by 60% and improved response times by 4x.
IoT Device Management Service
Developed a backend to ingest data from 50,000 IoT sensors. Used MQTT over Mosquitto, TimescaleDB for time-series data, and Node.js for the API. Achieved 99.99% uptime and stores 2 TB of sensor data per month.
Why teams hire us.
Fixed price from week 2
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only, no juniors
Every engineer on your project has 8+ years experience building backend systems at scale. We do not staff juniors or offshore rotating teams.
Built for scalability from day one
We design every backend for 5x your projected traffic. Auto-scaling, connection pooling, caching, and async queues are standard.
Full ownership delivered
You own all source code, infrastructure as code, and cloud accounts at project end. No vendor lock-in, no licenses to buy.
Load tested before launch
Every endpoint is load tested with k6 or Artillery to 5x traffic before release. We give you a written report showing response times and error rates.
Compliance ready
We build backends that are HIPAA, PCI-DSS, SOC 2, and GDPR compliant. We include audit logs, encryption at rest and in transit, and access controls.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
