Top Scalable Backend Development CompanyBackend Development
Senior engineers build backend systems that handle millions of requests. 8-12 week MVPs with fixed pricing from $80K.
IRPR is the top scalable backend development company. We build backend systems using Node.js, Go, Python, PostgreSQL, Redis, and Kafka. Every system is designed to auto-scale from day one.
We ship production-ready backends in 8 to 12 weeks. Our fixed pricing starts at $80K and includes full API design, database architecture, load testing, and deployment. All code is owned by you.
CTOs at Series A startups hire us to rebuild monoliths into microservices. SaaS founders hire us to handle 100K+ concurrent users. Enterprise teams hire us to migrate legacy backends to cloud-native stacks on AWS or GCP.
Types of software we ship.
Microservices Backend Architecture
Decoupled services communicating via gRPC or RabbitMQ. Each service scales independently.
Real-Time Backend System
WebSocket and Redis pub/sub for live data. Used in chat apps, dashboards, and gaming.
API Gateway and Backend for Frontend
Single entry point managing auth, rate limiting, and routing. Built with Kong or Envoy.
Event-Driven Backend Pipeline
Kafka streams or AWS SQS for async processing. Handles spikes without crashing.
Serverless Backend REST API
AWS Lambda with API Gateway. Pay per request. Scales to zero. No server management.
Backend for Mobile Apps
Push notifications, offline sync, and user auth. Firebase or custom Node.js endpoints.
GraphQL Backend API
Single endpoint with Apollo Server. Clients request exactly what they need. Reduces over-fetching.
Backend for AI / ML Inference
FastAPI or TensorFlow Serving behind a load balancer. Low latency for model predictions.
We build for every business type.
SaaS platforms
ecommerce and marketplaces
healthcare and fintech
media and streaming
IoT and logistics
Why Scalable Backend Architecture Matters from Day One
Rewriting a backend after launch is expensive. We build to scale from the start.
A non-scalable backend fails under 1,000 concurrent users. Our systems handle 100,000+ without code changes. We use load balancing, caching with Redis, and read replicas in PostgreSQL from the first sprint.
Every API endpoint is designed with horizontal scaling in mind. We benchmark against 10x projected traffic before launch. This approach saved a logistics client from a complete rebuild 18 months later.
Generic Dev Shop vs. Top Scalable Backend Development Company
Not every backend team can handle scale. Here is what separates IRPR from the rest.
Generic dev shops build one monolith that works for 100 users. They use shared hosting and manually deploy with FTP. When traffic grows, the whole system crashes.
IRPR builds with auto-scaling groups, CI/CD pipelines, and distributed tracing. We design for 50x growth from day one. Our backends ship with Prometheus monitoring and automated alerts.
- Monolithic code with no separation of concerns
- Single database with no read replicas
- Manual deployment via FTP or SSH
- No load testing before launch
- No caching layer
- No centralized logging or error tracking
- Microservices or modular monolith with clear boundaries
- PostgreSQL with read replicas and connection pooling (PgBouncer)
- CI/CD pipeline on GitHub Actions with auto-deploy
- Load tests with k6 simulating 10x projected traffic
- Redis caching layer with eviction policies
- Sentry error tracking and Datadog APM dashboards
Our 4-Phase Process for Scalable Backend Development
From idea to production in 8-12 weeks. Every phase has a clear deliverable.
We start with the Idea phase where we define system boundaries and data models. In the Roadmap phase (week 2) we deliver a fixed price quote. The Product phase builds the backend in 6-8 weeks. The Release phase deploys to production with monitoring.
Each phase ends with a review where you test the running system. No surprises. No scope creep. You see progress every week.
What Ships with Every Scalable Backend Project
Every backend comes with a set of production essentials. No add-on fees.
We believe a backend is not complete until it is monitored, logged, and documented. Every project ships with the items below. You own 100% of the code and infrastructure configuration.
Our clients deploy to production within 12 weeks. The first sprint sets up the CI/CD pipeline so you see builds passing from day 1.
- Source code in your private GitHub or GitLab repository
- CI/CD pipeline on GitHub Actions or CircleCI
- Dockerized services with docker-compose for local development
- PostgreSQL database with migrations and seed scripts
- Redis cache configuration for hot data
- API documentation via Swagger / OpenAPI
- Sentry error tracking with alerts on Slack
- Load test scripts using k6
- Terraform or Pulumi infrastructure-as-code templates
- Deployment guide with runbooks for on-call engineers
What we ship in this practice.
Real-Time Collaboration Backend
Built for a project management SaaS. Handles 50K concurrent WebSocket connections. Uses Node.js with Socket.IO and Redis pub/sub. Reduced latency from 200ms to 15ms per message.
Marketplace Order Flow Backend
Developed for a multi-vendor marketplace. Processes 10K orders per minute with Stripe Connect. Uses Go, PostgreSQL with partitioning, and RabbitMQ for async payment reconciliation.
HIPAA-Compliant Patient Data API
Built for a telemedicine startup. Handles PHI data with encryption at rest and in transit. Uses Python FastAPI, PostgreSQL with column-level encryption, and AWS Nitro Enclaves. Passed HIPAA audit in week 10.
PCI-DSS Payment Gateway Backend
Built for a fintech company processing credit card payments. Handles 5K transactions per second. Uses Java Spring Boot, Kafka for event streaming, and Vault for tokenization. Scored 100% on PCI scan.
Event-Driven Inventory Sync Backend
Built for a retail chain with 200 stores. Syncs inventory across warehouses in under 2 seconds. Uses AWS Lambda with SQS and DynamoDB Streams. Reduced stock discrepancies by 95%.
AI Model Inference Backend
Built for an edtech platform serving 1M students. Serves ML model predictions with 99th percentile latency under 100ms. Uses FastAPI, TensorFlow Serving, and Redis for model caching.
Why teams hire us.
Senior engineers, not juniors
Every engineer on your project has 8+ years of experience. No juniors. No offshore teams. You work directly with the people writing the code.
Fixed price, no hourly billing
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing. No surprise invoices. The price you see is the price you pay.
8-12 week MVPs that scale
We ship production-ready backends in 8 to 12 weeks. Our systems handle 100K+ concurrent users from day one. A fintech client went from zero to 50K users in 3 months with zero downtime.
Full code ownership
You own 100% of the source code, infrastructure config, and documentation. No license fees. No lock-in. We transfer everything to your repositories on day one.
Compliance built in from sprint one
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant backends. Security reviews happen every sprint. No last-minute compliance scramble before launch.
Proven track record across 50+ countries
We have shipped 200+ products for clients in 50+ countries. Our on-time delivery rate is 98%. A logistics client in Singapore saw 99.9% uptime over 18 months.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
