Best Scalable Backend Development ConsultantsScalable Backend
We build backends that handle 10x traffic without breaking. Fixed price, 8-12 week delivery, senior engineers only.
IRPR is a team of senior backend engineers who build scalable backend systems for startups and enterprises. We use Node.js, Go, Python, PostgreSQL, Redis, Kafka, and cloud-native services on AWS, GCP, and Azure to design architectures that scale from zero to millions of users.
Every project ships in 8-12 weeks with a fixed price. Our backend consulting engagements range from $80K to $250K depending on complexity. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA out of the box.
Founders with a validated idea hire us to build their backend from scratch. CTOs at Series A-B companies bring us in to refactor monolithic backends into microservices. Enterprise architects engage us to design event-driven systems for real-time data processing.
Types of software we ship.
Microservices architecture
Decoupled services communicating via gRPC or Kafka. Each service scales independently. We use Docker and Kubernetes for orchestration.
RESTful API development
Stateless APIs with OpenAPI specs, rate limiting, and caching. Built with Express.js, FastAPI, or Gin. Includes Swagger documentation.
GraphQL backend
Single endpoint with Apollo Server or Hasura. Resolvers optimized with DataLoader to prevent N+1 queries. Real-time subscriptions via WebSockets.
Event-driven backend
Asynchronous processing with Kafka, RabbitMQ, or AWS SQS. Handles high-throughput data streams for analytics, logging, and notifications.
Serverless backend
Lambda functions, API Gateway, DynamoDB, and Step Functions. Auto-scales to zero when idle. Pay-per-execution pricing model.
Real-time backend
WebSocket servers with Socket.io or AWS AppSync. Supports live chat, collaborative editing, and live dashboards. Sub-millisecond latency.
Backend for mobile apps
Push notifications via Firebase Cloud Messaging, offline sync with Realm, and user authentication with Auth0 or Cognito. Optimized for low bandwidth.
Data pipeline backend
ETL pipelines with Airflow, dbt, and Snowflake. Processes terabytes of data daily. Includes monitoring with Datadog and alerting with PagerDuty.
We build for every business type.
SaaS companies
Fintech and payments
Healthcare and life sciences
Ecommerce and retail
Enterprise and logistics
Why Scalable Backend Architecture Matters
A backend that works for 100 users will fail at 10,000 if it is not built for scale from day one.
IRPR designs backends with horizontal scaling in mind. We use stateless services, database read replicas, and caching layers with Redis or Memcached. Our systems handle traffic spikes from viral launches or seasonal campaigns without downtime.
We also implement circuit breakers, retry logic, and rate limiting to protect downstream services. Every endpoint is monitored with Datadog dashboards and PagerDuty alerts. Our clients see 99.9% uptime even under peak load.
Generic Dev Shop vs IRPR
Not all backend consultants deliver the same quality. Here is how IRPR differs from a generic development shop.
Generic shops assign junior developers to your project and bill by the hour. They often skip load testing, monitoring, and documentation. You end up with a backend that works in staging but crashes in production.
IRPR assigns senior engineers only. We write automated tests, set up CI/CD pipelines, and run load tests with k6 before launch. Every project includes a post-launch support period of 30 days.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No load testing before launch
- No monitoring or alerting setup
- No documentation or API specs
- Code ownership unclear
- Senior engineers with 8+ years experience
- Fixed price from the Roadmap phase
- Load testing with k6 and Locust
- Datadog monitoring and PagerDuty alerts
- OpenAPI specs and architecture diagrams
- Full code ownership transferred to you
Our Backend Development Process
We follow a four-phase process that turns your idea into a production-ready backend in 8-12 weeks.
Phase 1 is the Idea phase where we clarify requirements and define success metrics. Phase 2 is the Roadmap phase where we produce a detailed technical specification, architecture diagram, and fixed price quote.
Phase 3 is the Product phase where we build the backend in 2-week sprints. You see working software every sprint. Phase 4 is the Release phase where we deploy to production, run load tests, and hand over all code and documentation.
What Ships With Every Backend
Every backend project includes these deliverables by default. No hidden extras.
We believe in full transparency. You get everything you need to run and maintain the backend yourself. No black boxes, no proprietary tools.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker Compose and Kubernetes manifests
- OpenAPI 3.0 specification for all endpoints
- Database schema migration scripts
- Load test scripts with k6
- Datadog dashboard and alert configuration
- Post-launch support for 30 days
- Architecture diagram in Draw.io format
- Admin panel with user management and logs
What we ship in this practice.
Real-time analytics backend for a SaaS platform
Built a streaming data pipeline with Kafka, Flink, and ClickHouse. Processes 10 million events per day with sub-second query latency. Reduced dashboard load time from 8 seconds to 200 milliseconds. Tech stack: Kafka, Flink, ClickHouse, Node.js, AWS EKS.
HIPAA-compliant backend for a telemedicine app
Designed a microservices backend with encrypted patient data storage, audit logging, and role-based access control. Handles 500 concurrent video consultations. Passed HIPAA audit on first attempt. Tech stack: Go, PostgreSQL, Redis, AWS ECS, Auth0.
Payment processing backend for a fintech startup
Built a PCI-DSS compliant payment engine with Stripe Connect integration. Supports multi-currency transactions, automatic reconciliation, and fraud detection. Processes $2 million in monthly transactions. Tech stack: Python, FastAPI, PostgreSQL, Stripe, AWS Lambda.
Inventory management backend for an ecommerce brand
Created a real-time inventory system with WebSocket updates and predictive restocking. Integrates with Shopify, Amazon, and warehouse APIs. Reduced stockouts by 40%. Tech stack: Node.js, Redis, MongoDB, AWS AppSync, Shopify API.
Multi-tenant backend for a B2B SaaS CRM
Architected a database-per-tenant model with automated provisioning and backup. Supports 200 tenants with zero downtime during tenant onboarding. Tech stack: Ruby on Rails, PostgreSQL, Sidekiq, AWS RDS, Datadog.
IoT data ingestion backend for a logistics company
Built a serverless pipeline that ingests GPS and sensor data from 10,000 devices every 30 seconds. Uses AWS IoT Core, Kinesis, and S3 for storage. Reduced data processing cost by 60%. Tech stack: AWS IoT Core, Kinesis, Lambda, DynamoDB, Python.
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 single line of code.
Senior engineers only
Our team averages 10 years of backend experience. No junior developers, no offshore interns. Every engineer has shipped production systems handling millions of requests per day.
8-12 week delivery
We ship working software in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects finish on time.
Full code ownership
You own all source code, documentation, and infrastructure configuration. No licensing fees, no vendor lock-in. You can take the code and run it anywhere.
Built-in compliance
We build backends that meet HIPAA, PCI-DSS, SOC 2, and FERPA requirements. Our engineers know the compliance standards and implement controls from day one.
Post-launch support
Every project includes 30 days of post-launch support. We monitor the system, fix any issues, and help your team take over. After that, we offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
