Senior Scalable Backend Development AgencyDevelopment Agency
We build backends that handle millions of requests. Go, Rust, Node.js, and cloud-native architectures from senior engineers.
IRPR builds scalable backend systems using Go, Rust, Node.js, and Python. We design for high concurrency, low latency, and fault tolerance.
A typical backend project ships in 12-14 weeks. Fixed pricing ranges from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance.
Startups needing a production-ready API for their SaaS. Series A companies scaling from 10K to 1M users. Enterprise teams replacing legacy monoliths. Fintech firms requiring sub-100ms latency.
Types of software we ship.
RESTful API Development
Build high-performance REST APIs with Express.js, FastAPI, or Go Fiber. Includes OpenAPI docs, rate limiting, and auth. Designed for 10K+ requests per second.
GraphQL Backend
Create flexible GraphQL APIs using Apollo Server or Yoga. Supports subscriptions, caching with Redis, and schema stitching for multiple data sources.
Real-Time Data Streaming
Implement real-time pipelines with Apache Kafka, AWS Kinesis, or RabbitMQ. Processes millions of events per minute with exactly-once semantics.
Microservices Architecture
Decompose monoliths into microservices with Docker, Kubernetes, and service mesh (Istio). Each service can be scaled independently.
Event-Driven System
Build async event-driven systems using AWS Lambda, SQS, and EventBridge. Triggers include webhooks, database changes, and scheduled tasks.
Serverless Backend
Deploy serverless backends with AWS Lambda, API Gateway, and DynamoDB. Pay only for compute time, scales automatically to millions of users.
Third-Party API Integration
Integrate with Stripe, Salesforce, HubSpot, and dozens of other APIs. Includes retry logic, rate limit handling, and webhook reconciliation.
Database Optimization and Migration
Optimize PostgreSQL, MySQL, or MongoDB queries. Migrate from legacy databases to cloud-native options like Aurora or CockroachDB with zero downtime.
We build for every business type.
E-commerce and Retail
Fintech
Healthcare
SaaS and Tech

Why a Senior Scalable Backend Development Agency Matters
Building backend systems that scale requires experience across distributed systems, databases, and cloud infrastructure.
Generic dev shops often build monoliths that break under load. Senior engineers at IRPR design for scalability from day one using proven patterns like CQRS, event sourcing, and sharding.
We have shipped 200+ backend systems across 50+ countries. Our backends handle peaks of 100K requests per second with 99.9% uptime.
Senior Backend Development vs Generic Outsourcing
Not all backend development is equal. Here's how IRPR differs from a typical dev shop.
Generic shops assign junior developers who learn on your project. They use outdated stacks and produce undocumented code that fails under load.
IRPR assigns senior engineers with 8+ years of experience. We use modern stacks like Go, Rust, and TypeScript. Every project includes documentation, tests, and CI/CD.
- Junior developers with 1-2 years experience
- Unclear scope leading to costly change orders
- Monolithic architecture that cannot scale
- No automated testing or CI/CD
- No ownership of code quality or performance
- Hourly billing with no fixed price
- Senior engineers with 8+ years experience
- Fixed price from Roadmap phase
- Microservices or serverless from day one
- Full CI/CD with automated tests and monitoring
- Code ownership and post-launch support
- Transparent fixed pricing, no surprises
Our Backend Development Process
We follow a proven 4-phase process to build scalable backends in 12 weeks.
Phase 1: Discovery and Architecture. We map your data model, API endpoints, and infrastructure needs. Deliverable: a detailed architecture document.
Phase 2: Rapid Development. We build core APIs, integrate databases, and set up CI/CD. Daily standups and weekly demos keep you informed.
What Ships With Your Backend
Every backend project includes these deliverables by default.
No hidden line items. Everything listed here is included in the fixed price.
- Source code in your private Git repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code with Terraform or Pulumi
- API documentation with Swagger or GraphQL playground
- Unit and integration tests with 80%+ coverage
- Dockerized development and production environments
- Monitoring and alerting with Datadog or Grafana
- Error tracking with Sentry
- Database backup and disaster recovery plan
- Post-launch support for 30 days
What we ship in this practice.
Real-Time Payment Processing API
Built a payment processing backend for a fintech startup using Node.js, PostgreSQL, and Stripe. The system handles 10K transactions per second with sub-200ms latency and reduced failed payments by 35%.
Patient Data Exchange Backend
Developed a HIPAA-compliant backend for a healthcare network using Python FastAPI and AWS. Connected 12 hospitals, enabling real-time patient data sharing and reducing lab result delivery from 4 hours to 3 minutes.
E-commerce Order Management System
Built an order processing backend with Go, Redis, and RabbitMQ for a fast-growing ecommerce brand. Scaled from 1K to 100K orders per day during Black Friday with zero downtime.
SaaS Multi-Tenant API Gateway
Created a multi-tenant API gateway using Node.js, PostgreSQL, and Kong for a SaaS platform. Handles 50K tenants with per-tenant rate limiting and data isolation. Reduced onboarding time from 2 weeks to 2 days.
IoT Data Ingestion Pipeline
Built a real-time data ingestion service for a manufacturing company using Kafka, InfluxDB, and Go. Processes 1 million sensor readings per second and triggers alerts for anomalies within 100ms.
Personalized Recommendation Engine
Developed a recommendation backend for a media streaming platform using Python, Cassandra, and Redis. Increased user engagement by 25% through real-time content suggestions based on viewing history.
Why teams hire us.
Senior Engineers Only
Every developer on your project has 8+ years of backend experience. No junior developers, no offshore teams, no knowledge gaps.
Fixed Price from Day One
We give you a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprises, no scope creep charges.
12-Week MVP Delivery
Most backend projects ship in 12-14 weeks. We work in 2-week sprints with weekly demos so you see real progress.
Built for Scale
We design for 10x growth from the start using microservices, event-driven architectures, and cloud-native tools. Our backends handle millions of requests with 99.9% uptime.
Full Code Ownership
You own all source code, infrastructure scripts, and documentation. No lock-in, no licensing, no hidden fees.
Post-Launch Support
We include 30 days of post-launch support to handle issues, optimize performance, and train your team. After that, we offer ongoing maintenance contracts.
