Scalable Backend Development DevelopersBackend Development
We build backends that handle 10x traffic without breaking. Fixed price, senior engineers only.
IRPR builds scalable backends using Node.js, Go, and event-driven architecture on Kubernetes. We design microservices that auto-scale under load and recover from failures without downtime.
Typical projects ship in 12 to 14 weeks with fixed pricing from $80K to $250K. Every backend we build meets SOC 2, PCI-DSS, or HIPAA standards, and we handle penetration testing as part of delivery.
SaaS founders hire us to handle 1M+ concurrent users. Fintech CTOs need PCI-compliant payment APIs. Healthcare startups require HIPAA-compliant data pipelines. Ecommerce managers need backends that survive Black Friday spikes without a 503 error.
Types of software we ship.
Microservices architecture
Decouple monolithic apps into independent services. Each deploys and scales separately using Docker and Kubernetes.
API gateway development
A single entry point for multiple services with rate limiting, auth, and caching. Built with Kong or Envoy.
Real-time data pipeline
Ingest and process millions of events per second with Apache Kafka and stream processing in Go.
Event-driven system
Asynchronous communication between services using RabbitMQ or AWS SQS. Enables loose coupling and independent scaling.
Serverless backend
Stateless functions on AWS Lambda or Google Cloud Functions. Pay only for compute time, no server management.
GraphQL API
Flexible queries with Apollo Server and a federated gateway. Reduces over-fetching and consolidates multiple REST endpoints.
Message queue system
Reliable task distribution with RabbitMQ, AWS SQS, or Kafka. Decouples producers and consumers for fault tolerance.
Load balancer configuration
Distribute traffic across instances with Nginx, HAProxy, or AWS ALB. Includes health checks, SSL termination, and auto-scaling.
We build for every business type.

Media and streaming
Scalable Backend Development Developers: What We Deliver
Every backend we ship is built for traffic, not guesswork.
IRPR has shipped 200+ scalable backends for clients in 50+ countries. Our engineering team uses Node.js, Go, Python, and Rust depending on the workload. We containerize every service with Docker and orchestrate with Kubernetes, testing auto-scaling rules under simulated load before launch.
We handle compliance out of the box. Backends for healthcare clients follow HIPAA rules with BAA agreements and data encryption at rest and in transit. Fintech projects pass PCI-DSS Level 1 audits. Ecommerce backends handle 100k+ orders per hour without degradation, and we provide SLA-backed uptime of 99.9%.
How IRPR Compares to Generic Dev Shops
Most agencies bill by the hour and leave you with no ownership. IRPR gives you a finished, scalable system.
Generic dev shops often build monolithic backends that crumble under load. They use hourly billing, so every scaling issue becomes a new contract. They rarely test for traffic spikes and leave you with no documentation.
IRPR builds microservices from day one, tests with load generators like k6, and delivers full ownership. We include CI/CD pipelines, monitoring with Datadog, and a 30-day post-launch warranty. You get a system that scales without rewriting.
- Monolithic architecture that fails at 10x traffic
- Hourly billing with no price cap
- No load testing in the contract
- You don't own the code by default
- No compliance reviews (HIPAA, PCI)
- Takes 6+ months for a production-ready backend
- Microservices on Kubernetes that auto-scale
- Fixed price from $80K, no surprises
- Load testing with k6 in the Roadmap phase
- Full code ownership from day one
- HIPAA, PCI-DSS, SOC 2 built in
- 12 to 14 weeks to production
The Process: From Idea to Scalable Backend
We move from concept to production in four phases, each with a clear deliverable.
Phase 1 is the Idea workshop where we map your traffic expectations and data models. Phase 2 is the Roadmap: a fixed-price plan with architecture diagrams, tech stack choices, and a timeline. Phase 3 is Product: building the backend in 2-week sprints with daily demos. Phase 4 is Release: deployment, load testing, and handover.
During the Roadmap phase (week 2), you get a detailed price quote. No changes after that point unless you request new features. The timeline is based on your number of services: a simple API gateway with 3 microservices takes 10 weeks; a full event-driven system with 10+ services takes 14 weeks.
What Ships with Every Scalable Backend
We don't just deliver a backend. We deliver a production-ready system you can operate immediately.
Every project ends with a handover session where we walk your team through the architecture. You get full ownership of all code, infrastructure-as-code templates, and runbooks for common operations like scaling and disaster recovery.
IRPR includes a 30-day post-launch warranty where we fix any bugs and handle initial load spikes. After that, you can extend with a monthly retainer for ongoing maintenance or internalize the codebase.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions (tests, builds, deploys)
- Docker images and Kubernetes manifests
- Sentry error tracking with alerts to Slack
- Datadog monitoring dashboards for CPU, memory, latency
- Load test reports from k6 (10x expected traffic)
- API documentation with Swagger or Postman
- Runbooks for scaling, backup, and incident response
- 30-day warranty with same-day bug fixes
- One architecture walkthrough session with your team
What we ship in this practice.
Payment processing API for a fintech startup
IRPR built a PCI-DSS compliant API on Go and PostgreSQL that processes 10,000 transactions per second. The client reduced payment failures by 30% and passed a Level 1 audit on the first attempt.
Real-time chat backend for a telehealth platform
We designed an event-driven system with WebSocket connections on Node.js and Redis pub/sub. The backend handled 500,000 concurrent users with 99.9% uptime and met HIPAA requirements for message encryption.
Order fulfillment backend for an ecommerce marketplace
Using microservices on Kubernetes, we built a system that processes 100,000 orders per hour during Black Friday. The client saw zero downtime and 40% faster order confirmation.
Analytics pipeline for a SaaS platform
IRPR created a data pipeline using Kafka, Flink, and ClickHouse that ingests 10 million events per day. The client reduced report generation time from 30 minutes to 2 seconds.
Video transcoding backend for a media startup
We built a serverless pipeline on AWS Lambda and S3 that transcodes 50,000 videos per month. The client saved 60% on compute costs compared to their previous EC2-based solution.
Inventory sync backend for a multi-channel retailer
A GraphQL API on Node.js and PostgreSQL synchronizes inventory across Shopify, Amazon, and physical stores in real time. The client eliminated overselling and reduced manual reconciliation by 20 hours per week.
Why teams hire us.
Fixed price, not hourly
Every scalable backend project has a fixed quote after the Roadmap phase (week 2). No hourly billing means no incentive to drag the timeline. If we find a better way to scale, you pay the same price.
Senior engineers only
IRPR hires engineers with 8+ years of experience in distributed systems. Our team includes ex-Stripe and ex-Amazon engineers who have built backends for 100M+ users. No junior developers touch your code.
8-12 week MVPs to production
We ship production-ready backends in 12 to 14 weeks. The first working endpoints are visible in week 3. This lets you test assumptions early and avoid building features nobody uses.
Full code ownership
You own every line of code from day one. There are no licenses, royalties, or IP restrictions. We deploy to your AWS or GCP account using your existing infrastructure.
Compliance built into the build
HIPAA, PCI-DSS, SOC 2, and GDPR compliance are part of the architecture, not an afterthought. We include encryption, logging, and audit trails in every backend. Our clients pass audits on the first try.
Async-first communication
Our team works across 3 time zones and communicates via Slack and Linear. You get daily updates without status meetings. For clients in New York, London, or San Francisco, we overlap 4 hours daily for real-time calls.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
