Expert Scalable Backend Development AgencyScalable Backend
We build backend systems that handle millions of requests. 200+ products shipped across 50 countries.
IRPR is an expert scalable backend development agency. We use Node.js, Go, PostgreSQL, Redis, and AWS to build systems that scale from day one. Every project starts with a clear architecture plan.
We deliver production-ready backends in 8-12 weeks. Fixed pricing starts at $80K and goes to $250K depending on complexity. All systems include automated CI/CD, monitoring, and 99.9% uptime SLA.
Our clients are CTOs scaling their platforms, product managers launching new features, and startup founders building MVPs. We also work with enterprise teams modernizing legacy backends.
Types of software we ship.
API Development
REST and GraphQL APIs with rate limiting, caching, and versioning. Built with Node.js or Go, deployed on AWS Lambda or ECS.
Microservices Architecture
Decoupled services with event-driven communication using Kafka or RabbitMQ. Each service scales independently.
Database Scaling
Horizontal sharding, read replicas, and connection pooling for PostgreSQL or MySQL. Handles millions of writes per second.
Real-Time Systems

Why Choose an Expert Scalable Backend Development Agency
Building a backend that handles growth requires more than just code. It requires architecture decisions that pay off at scale.
IRPR has shipped over 200 backend systems. Each one is built with horizontal scaling, fault tolerance, and observability in mind. We use tools like Terraform for infrastructure, Prometheus for monitoring, and OpenTelemetry for tracing.
Our backends handle peaks of 10,000 requests per second without breaking. We design for 10x growth from day one, so you don't have to rewrite later.
The Difference Between Generic Dev Shops and IRPR
Not all agencies build backends that scale. Here is what sets IRPR apart.
Generic dev shops write code that works today but breaks tomorrow. They use one-size-fits-all stacks and skip load testing. You end up with slow APIs and unplanned rewrites.
IRPR engineers are senior-level only. We design for scale, write automated tests, and deliver a production-ready system with monitoring, logging, and alerts. Every project includes a 30-day post-launch warranty.
- No load testing before launch
- Single-server architecture
- No CI/CD pipeline
- No monitoring or alerting
- Hourly billing with scope creep
- Code ownership unclear
- Load tested to 10,000 RPS
- Auto-scaling on AWS or GCP
- CI/CD with GitHub Actions
- Prometheus + Grafana monitoring
- Fixed price, no surprises
- Full source code ownership
How We Build Scalable Backends: Our 4-Phase Process
Every project follows a repeatable process that de-risks development and ensures on-time delivery.
Phase 1: Architecture Design. We map out your data flow, choose the right database (PostgreSQL, DynamoDB, or Redis), and define API contracts. This takes 1-2 weeks and costs $5K-$10K.
Phase 2: Core Development. We build the MVP backend with authentication, CRUD APIs, and integrations. You get a working system in 6-8 weeks. Phase 3: Load Testing & Hardening. We simulate production traffic, fix bottlenecks, and add caching. Phase 4: Deployment & Monitoring. We set up Terraform, CI/CD, and dashboards.
What Ships with Every Scalable Backend Project
You get more than just code. Every deliverable is documented and production-ready.
We believe in full transparency. You own everything we build, from source code to infrastructure scripts. No black boxes, no vendor lock-in.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containers for every service
- Terraform scripts for AWS infrastructure
- API documentation (Swagger/OpenAPI)
- Sentry error tracking
- Prometheus + Grafana monitoring dashboards
- Load test results report
- Post-launch 30-day warranty
- Architecture decision record (ADR) document
What we ship in this practice.
E-Commerce Order Processing Backend
Built a microservices backend for an online retailer. Handles 5,000 orders per minute during Black Friday. Uses Node.js, PostgreSQL with read replicas, and Kafka for event streaming. Reduced order processing time from 30 seconds to 2 seconds.
Fintech Payment Orchestration Layer
Developed a payment routing backend that connects to Stripe, PayPal, and Adyen. Processes $2M in transactions per month. Built with Go, Redis for rate limiting, and AWS Fargate. Achieved 99.99% uptime over 12 months.
Healthcare Patient Scheduling API
Created a HIPAA-compliant backend for a telemedicine platform. Handles 10,000 appointment bookings per day. Uses PostgreSQL with encryption at rest, AWS KMS for keys, and HL7 FHIR integration. Reduced scheduling errors by 80%.
SaaS Multi-Tenant Backend for Analytics
Designed a multi-tenant backend with row-level security in PostgreSQL. Serves 500+ tenants with isolated data. Built with Node.js, GraphQL, and Redis caching. Query response times under 50ms at P99.
Real-Time Chat Backend for Media Platform
Built a WebSocket-based chat backend supporting 1 million concurrent connections. Uses Socket.IO with Redis adapter and horizontal scaling on AWS ECS. Message delivery latency under 100ms. Handles 50,000 messages per second.
Logistics Tracking API
Developed a shipment tracking backend that aggregates data from 3 carrier APIs. Processes 200,000 tracking updates per hour. Uses Go, MongoDB for flexible schemas, and Kafka for event streaming. Reduced tracking latency from 5 minutes to 10 seconds.
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 total cost before we write a line of code.
Senior engineers only
IRPR hires engineers with 8+ years of experience. No juniors, no offshore teams. Every developer has shipped at least 10 production backends. Average tenure on our team is 4 years.
8-12 week MVPs
We deliver a production-ready backend in 8-12 weeks. This includes architecture, development, testing, and deployment. Your team can start integrating on day one of the launch.
Full code ownership
You own everything we build. Source code, Docker images, Terraform scripts, CI/CD configurations. No licensing fees, no proprietary frameworks. You can take it anywhere.
Production monitoring included
Every project ships with Prometheus, Grafana, and Sentry. We set up dashboards and alerts for error rates, latency, and throughput. You know when something breaks before your users do.
30-day post-launch warranty
After launch, we provide 30 days of hands-on support. Bug fixes, performance tuning, and documentation updates. No extra charges. We make sure your backend runs smoothly.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
