Scalable Backend Development FirmBackend Development
We build backend systems that handle 10x traffic without breaking. Fixed price, 12 weeks, full ownership.
IRPR is a scalable backend development firm. We build backend systems using Node.js, Go, Python, AWS Lambda, Kubernetes, and PostgreSQL. Every system is designed to scale horizontally from day one.
We ship production-grade backend architecture in 12-14 weeks. Fixed pricing ranges from $80K to $250K depending on complexity. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA out of the box.
CTOs hire us when their monolithic backend can't handle growth. Startup founders hire us to build a scalable MVP that won't need a rewrite. Enterprise teams hire us to modernize legacy APIs and reduce latency by 60% or more.
Types of software we ship.
REST API development
Stateless, versioned APIs with OpenAPI specs. Built with Express.js or Fastify, deployed on AWS ECS.
GraphQL backend
Unified data layer using Apollo Server or Hasura. Reduces frontend requests by 80% and speeds up mobile apps.
Microservices architecture
Decoupled services communicating via gRPC or message queues. Each service scales independently on Kubernetes.
Event-driven backend
Asynchronous processing with Kafka, RabbitMQ, or AWS SQS. Handles spikes in traffic without backpressure.
Real-time backend
WebSocket and SSE backends for live dashboards, chat, and notifications. Built with Socket.io or AWS AppSync.
Serverless backend
AWS Lambda + API Gateway + DynamoDB. Zero server management, auto-scales to millions of requests per day.
Backend for mobile apps
Push notifications, user auth, file uploads, and offline sync. Firebase or custom Node.js with PostgreSQL.
Legacy backend migration
Move from PHP, Ruby, or .NET to Node.js or Go. Strangler pattern, zero downtime, 40% lower cloud costs.
We build for every business type.
SaaS platforms
ecommerce and marketplaces
healthcare and fintech
media and content platforms
logistics and IoT
Why a scalable backend development firm matters
A scalable backend is the difference between handling 100 users and 1 million users.
IRPR has shipped over 200 backend systems. Every one of them is built to scale horizontally. We use load testing tools like k6 and Artillery to verify that your backend can handle 10x your projected traffic before it goes live.
Our clients come to us after their in-house backend crashes under load. We rebuild with proper caching (Redis), async processing (BullMQ), and database indexing (PostgreSQL). The result: 99.9% uptime and sub-100ms response times.
Generic dev shops vs IRPR
Not every development firm can build a backend that scales. Here is the difference.
Generic dev shops treat backend as an afterthought. They copy-paste boilerplate, skip load testing, and hand you a system that works for 10 users but falls apart at 1000. You end up with a rewrite bill 6 months later.
IRPR treats backend as the foundation. We design for scale from the first commit. We use Infrastructure as Code (Terraform), CI/CD (GitHub Actions), and observability (Datadog). Your backend is production-ready on day one.
- No load testing before launch
- Monolithic architecture by default
- No caching strategy
- Manual deployment
- No monitoring or alerting
- No database indexing plan
- Load testing with k6 before every release
- Microservices or modular monolith based on traffic
- Redis caching with TTL strategy
- CI/CD pipeline on GitHub Actions
- Datadog monitoring with PagerDuty alerts
- PostgreSQL indexing and query optimization
How we build your scalable backend
Our process is designed to ship a production-grade backend in 12 weeks.
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price. No scope creep, no surprises.
By week 12, you have a backend that handles 10,000 concurrent users, integrates with your frontend, and runs on your own AWS account.
What ships with every backend
Every backend project includes these deliverables by default.
You own everything. Source code, infrastructure config, documentation, and CI/CD pipelines. No black boxes, no vendor lock-in.
We also include a 30-day warranty. If something breaks, we fix it free of charge.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as Code with Terraform
- API documentation with Swagger/OpenAPI
- Load test report from k6
- Datadog or Sentry monitoring setup
- PostgreSQL database with migrations and backups
- Redis cache with TTL configuration
- Dockerized development environment
- 30-day post-launch support
What we ship in this practice.
Multi-tenant SaaS backend
Built a tenant-isolated backend for a B2B SaaS company using Node.js, PostgreSQL with row-level security, and Redis caching. Reduced API response times by 65% and enabled each tenant to have custom rate limits.
Real-time logistics tracking API
Developed a WebSocket-based backend for a logistics startup using Go, Kafka, and MongoDB. Handles 50,000 location updates per second with sub-10ms latency. Reduced delivery delays by 30%.
HIPAA-compliant telehealth backend
Built a backend for a telemedicine platform using AWS Lambda, DynamoDB, and Twilio Video. Achieved HIPAA compliance with encryption at rest and in transit. Scaled to 10,000 concurrent video sessions.
Payment processing microservice
Designed a PCI-DSS compliant payment microservice using Stripe Connect, Node.js, and PostgreSQL. Processes 1,000 transactions per minute with idempotency keys to prevent duplicate charges.
Ecommerce search backend
Built a full-text search backend for an ecommerce platform using Elasticsearch, NestJS, and Redis. Reduced search response time from 2 seconds to 150ms. Increased conversion rate by 18%.
Content recommendation engine
Developed a recommendation API for a media company using Python, Redis, and PostgreSQL. Serves personalized content feeds to 500,000 daily active users. Increased user engagement by 40%.
Why teams hire us.
Fixed price, not hourly
Every backend project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the exact cost before we write a line of code.
12-week delivery guarantee
We ship production-grade backends in 12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects finish on time or early.
Full code ownership
You own the source code, infrastructure config, and all documentation. No licensing fees, no platform lock-in, no ongoing royalties. We transfer everything to your repos at launch.
Built for scale from day one
We design for horizontal scaling before we write the first API endpoint. Load testing with k6 is part of every sprint. Your backend can handle 10x traffic without a rewrite.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance as part of the build. Encryption, audit logs, access controls, and data retention policies are standard.
Senior engineers only
Every engineer at IRPR has 10+ years of experience. No juniors, no offshore teams, no handoffs. The same senior engineer who designs your architecture writes the code.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
