Experienced Scalable Backend Development DevelopersBackend Development
We build backend systems that handle millions of requests. Fixed price, 8-12 week delivery, full code ownership.
IRPR builds scalable backend systems for companies that need reliable, high-performance infrastructure. We use Node.js, Python, Go, PostgreSQL, Redis, Kafka, and cloud platforms like AWS and GCP to design architectures that scale from zero to millions of users.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code, CI/CD pipelines, and monitoring from day one.
CTOs hire us when their in-house team lacks bandwidth for a critical backend overhaul. Startup founders hire us to build a production-ready MVP that won't collapse under load. Enterprise architects hire us to migrate legacy monoliths to microservices on Kubernetes.
Types of software we ship.
REST API development
Build stateless REST APIs with Express.js or FastAPI. Includes OpenAPI docs, rate limiting, and JWT auth.
GraphQL backend
Implement GraphQL APIs with Apollo Server or Hasura. Supports real-time subscriptions and federated schemas.
Microservices architecture
Design event-driven microservices with Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
Real-time data pipeline
Build streaming data pipelines with Apache Kafka, Flink, or AWS Kinesis. Handles millions of events per second.
Serverless backend
Deploy serverless functions on AWS Lambda or GCP Cloud Functions. Auto-scales with zero cold start tuning.
Database architecture
Design relational and NoSQL databases with PostgreSQL, MongoDB, or DynamoDB. Includes indexing, sharding, and replication.
Authentication and authorization system
Implement OAuth 2.0, SAML, or OpenID Connect with Auth0 or custom JWT. Supports SSO and MFA.
Background job processing
Set up job queues with Bull, Sidekiq, or Celery. Handles email delivery, image processing, and data exports.
We build for every business type.
SaaS platforms
Ecommerce and marketplaces
Healthcare and fintech
Media and content platforms
IoT and logistics
Why experienced scalable backend development developers matter
A poorly designed backend costs you users, revenue, and engineering time.
IRPR has shipped 200+ backend systems across 50 countries. Our senior engineers average 10+ years of experience. We design for scale from day one: horizontal partitioning, caching layers with Redis, asynchronous processing with Kafka, and database sharding with PostgreSQL.
We use Terraform for infrastructure as code, GitHub Actions for CI/CD, and Datadog for monitoring. Every system achieves 99.9% uptime. We document every decision in a shared Notion workspace so your team can maintain it after handoff.
Generic dev shop vs IRPR
Not all backend developers deliver the same quality.
Many agencies promise scalable backend development but deliver monolithic code that breaks under load. They use junior developers, skip testing, and hand over undocumented spaghetti.
IRPR assigns senior engineers only. We write unit tests, integration tests, and load tests. We deliver a fully documented system with CI/CD, monitoring, and a runbook. Your team can take over in days, not months.
- Junior developers with 2 years experience
- No load testing before launch
- Monolithic architecture that can't scale
- No documentation or runbook
- Hourly billing with no cap
- Code ownership unclear
- Senior engineers with 10+ years experience
- Load testing with k6 and artillery before launch
- Microservices or modular monolith designed for scale
- Full documentation in Notion with architecture diagrams
- Fixed price from $80K to $250K
- You own 100% of the code
How we build your scalable backend
We follow a 4-phase process that guarantees delivery on time and on budget.
Phase 1 is the Idea phase where we map your requirements to a technical specification. Phase 2 is the Roadmap phase where we produce a fixed price quote and a detailed timeline. Phase 3 is the Product phase where we build and test. Phase 4 is the Release phase where we deploy and hand over.
Each phase has clear deliverables. You see progress every week. No surprises.
What ships with your backend
Every project includes these deliverables by default.
You get more than just code. We ship a complete system that your team can run and maintain independently.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code with Terraform or Pulumi
- Monitoring and alerting with Datadog or Grafana
- Load test results with k6 or artillery
- API documentation with Swagger or Postman
- Architecture diagrams in Draw.io or Miro
- Runbook with incident response procedures
- Sentry error tracking configured
- Post-deployment support for 30 days
What we ship in this practice.
Multi-tenant SaaS backend
Built a multi-tenant backend for a B2B analytics platform using Node.js, PostgreSQL, and Redis. Each tenant gets isolated data with row-level security. Reduced onboarding time from 2 weeks to 2 days. Tech stack: Node.js, PostgreSQL, Redis, AWS ECS.
Real-time payment processing engine
Designed a PCI-DSS compliant payment processing backend for a fintech startup. Handles 10,000 transactions per second with sub-100ms latency. Uses Go, Kafka, and PostgreSQL. Tech stack: Go, Kafka, PostgreSQL, AWS Fargate.
HIPAA-compliant patient data API
Built a HIPAA-compliant backend for a telemedicine platform. Supports 500 concurrent video sessions with end-to-end encryption. Uses Python, FastAPI, and PostgreSQL with encryption at rest. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS.
Ecommerce order processing system
Developed a scalable order processing backend for a multi-vendor marketplace. Processes 50,000 orders per day with real-time inventory sync. Uses Node.js, RabbitMQ, and MongoDB. Tech stack: Node.js, RabbitMQ, MongoDB, AWS EC2.
Real-time IoT data pipeline
Built a data ingestion pipeline for a logistics company that processes 1 million device events per minute. Uses Kafka, Flink, and TimescaleDB. Reduced data latency from 5 minutes to 2 seconds. Tech stack: Kafka, Flink, TimescaleDB, AWS Kinesis.
Social feed and notification engine
Created a real-time social feed backend for a media platform with 2 million daily active users. Uses GraphQL, Redis, and PostgreSQL. Delivers notifications in under 100ms. Tech stack: GraphQL, Redis, PostgreSQL, AWS Lambda.
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 cost before we write a line of code.
Senior engineers only
We hire engineers with 10+ years of experience. No juniors, no offshore teams. Every developer on your project has built production systems at scale.
Full code ownership
You own 100% of the source code, infrastructure configs, and documentation. No licensing fees, no vendor lock-in. Your team can take over anytime.
8-12 week delivery
We ship production-ready backends in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of projects deliver on time.
Built for scale from day one
We design for horizontal scaling, caching, and async processing from the start. Your system handles 10x growth without a rewrite. We load test with k6 before launch.
Compliance ready
We build backends that meet HIPAA, PCI-DSS, SOC 2, and FERPA requirements. We implement encryption, audit logging, and access controls by default.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
