Senior Scalable Backend Development DevelopersBackend Development
We build backend systems that handle millions of requests. 200+ products shipped with 99.9% uptime.
IRPR builds scalable backend systems using Node.js, Go, Python, and Rust. We design distributed architectures with PostgreSQL, Redis, Kafka, and Kubernetes to handle traffic spikes without breaking.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2. Our backend systems process over 10 million requests per day for clients in 50+ countries.
CTOs hire us when their monolithic backend starts failing under load. Startup founders hire us to build a scalable MVP that won't need a rewrite. Enterprise architects hire us to migrate legacy systems to microservices on AWS or GCP.
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 gRPC. Each service scales independently.
Real-time data pipeline
Build streaming pipelines with Apache Kafka or RabbitMQ. Process 100K+ events per second with low latency.
Serverless backend
Deploy serverless functions on AWS Lambda or Cloudflare Workers. Pay per execution, auto-scale to zero.
Database optimization
Optimize PostgreSQL or MongoDB queries. Add read replicas, sharding, and connection pooling for 10x throughput.
Authentication system
Implement OAuth 2.0, SAML, or OpenID Connect with Auth0 or Keycloak. Supports SSO and MFA out of the box.
CI/CD pipeline
Set up GitHub Actions or GitLab CI with automated testing, staging environments, and blue-green deployments.
We build for every business type.
SaaS platforms
Fintech companies
Healthcare platforms
Ecommerce and retail
Media and content
Why senior scalable backend development developers matter
A junior developer builds something that works today. A senior engineer builds something that works for years.
IRPR only hires senior engineers with 8+ years of experience. Every backend architect has shipped at least 5 production systems handling 1M+ requests per day. We use Node.js, Go, Python, and Rust because they give the best performance per dollar on AWS or GCP.
Our team has built backends for fintech platforms processing $50M in monthly transactions and healthcare systems storing 10 million patient records. Every system includes automated load testing, circuit breakers, and distributed tracing with OpenTelemetry.
Generic dev shop vs senior scalable backend development developers
Not all backend teams are equal. Here is what you get with IRPR.
Most dev shops assign junior developers to backend work. They use outdated patterns like monolithic Rails apps or PHP spaghetti. They skip load testing and monitoring. You end up with a system that crashes on Black Friday.
IRPR assigns a senior architect to every project. We design for scale from day one: horizontal scaling, database sharding, caching layers, and async processing. Every system ships with Grafana dashboards, PagerDuty alerts, and a runbook.
- Junior developers with 2 years experience
- Monolithic architecture that cannot scale
- No load testing before launch
- No monitoring or alerting
- Hourly billing with no fixed price
- Code ownership unclear
- Senior engineers with 8+ years experience
- Microservices or modular monolith designed for scale
- Load testing with k6 and Locust before launch
- Grafana dashboards and PagerDuty alerts
- Fixed price from Roadmap phase
- Full code ownership transferred to you
How we build scalable backend systems
Our process is designed to ship fast without cutting corners.
We start with a 2-week Roadmap phase. The senior architect maps out the system design, data model, API contracts, and deployment plan. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints. Every sprint ends with a deployable increment. You see working code every 14 days. We use feature flags and canary deployments to reduce risk.
What ships with every backend project
You get more than just code. Every project includes these deliverables.
We believe in full transparency. Every line of code is in your repository from day one. You can deploy without us if you want.
Our handoff package includes everything your team needs to maintain and extend the system. No black boxes, no hidden dependencies.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker containers for every service
- Kubernetes manifests for production deployment
- API documentation with Swagger or Postman
- Grafana dashboards for monitoring
- PagerDuty alerts for critical errors
- Sentry error tracking
- Load test results and capacity plan
- Runbook with incident response steps
What we ship in this practice.
Fintech payment processing backend
Built a payment processing system handling 50,000 transactions per day. Used Node.js, PostgreSQL, and Stripe Connect. Reduced failed transactions by 40% with automatic retries and idempotency keys.
Healthcare patient data API
Designed a HIPAA-compliant API for a telemedicine platform. Used Go, PostgreSQL, and AWS KMS for encryption. Handles 10 million patient records with sub-100ms response times.
Ecommerce inventory management
Built a real-time inventory system for a multi-warehouse retailer. Used Python, Redis, and Kafka. Reduced stockouts by 60% with predictive restocking algorithms.
SaaS analytics dashboard backend
Created a multi-tenant analytics backend processing 1 million events per day. Used Node.js, ClickHouse, and AWS Lambda. Queries return in under 2 seconds for 100+ tenants.
Real estate MLS data pipeline
Built a data pipeline ingesting MLS listings from 50+ sources. Used Python, PostgreSQL, and Apache Airflow. Reduced data sync time from 4 hours to 15 minutes.
EdTech assessment platform backend
Developed a FERPA-compliant backend for a K-12 assessment platform. Used Node.js, MongoDB, and AWS Cognito. Supports 100,000 concurrent users during peak testing periods.
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
IRPR does not hire juniors. Every engineer has 8+ years of experience and has shipped at least 5 production systems. You get a senior architect assigned to your project from day one.
8-12 week MVPs
We ship production-ready backend systems in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects ship on time.
Full code ownership
You own every line of code. We transfer the entire repository, CI/CD pipeline, and documentation at the end of the project. No licensing fees, no vendor lock-in.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant systems. Our engineers know the compliance requirements for healthcare, fintech, and enterprise SaaS. We handle audits and certifications.
99.9% uptime guarantee
Every system we build includes monitoring, alerting, and automated failover. We design for 99.9% uptime from the start. Our clients average 99.95% uptime in production.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
