Top Scalable Backend Development ConsultantsBackend Consultants
Your backend must handle 10x traffic without rewrites. IRPR builds auto-scaling, fault-tolerant systems that grow with your business.
IRPR builds scalable backend systems for companies that need to handle millions of requests from launch day. We use AWS Lambda, Kubernetes, Redis, and PostgreSQL to create stateless, horizontally scaling APIs that tolerate zero downtime.
Every engagement ships in 12 weeks at a fixed price between $100K and $350K. We comply with SOC 2, HIPAA, and PCI-DSS when required. Deliverables include source code, CI/CD pipelines, load testing reports, and 24/7 monitoring.
We work with CTOs at Series A startups hitting API rate limits, Heads of Engineering at mid-market SaaS companies migrating from monoliths, and Platform Leads at healthcare firms needing HIPAA-compliant backend infrastructure.
Types of software we ship.
Event-Driven Microservices
Decoupled services communicating via Apache Kafka or AWS SQS. Scale individual services independently without affecting others.
Serverless APIs
AWS Lambda + API Gateway + DynamoDB for pay-per-request scalability. Cold starts handled with provisioned concurrency.
Real-Time Data Pipelines
Stream processing with Apache Flink or Kinesis. Ingest, transform, and deliver data in under 100ms for dashboards and alerts.
GraphQL Gateways
Unify multiple microservices behind a single GraphQL endpoint using Apollo Federation. Reduce client payload by 50%.
Message Queue Systems
RabbitMQ or Amazon SQS for asynchronous job processing. Handle spikes without dropping requests. Decouple producers from consumers.

CQRS / Event Sourcing Systems
Separate read and write models with PostgreSQL and Elasticsearch. Rebuild state from event streams for full audit trails.
Multi-Region Database Clusters
CockroachDB or AWS Aurora Global Database for low-latency reads across US, EU, and APAC. RPO under 1 second.
We build for every business type.

What Scalable Backend Development Consultants Deliver
Our backend systems handle millions of requests per day with sub-50ms p99 latency and zero unplanned downtime.
Every project starts with a two-week Roadmap phase where we define the API contracts, data model, and scaling strategy. We use Terraform for infrastructure as code and set up multi-region deployment from day one. Load testing with k6 validates that each endpoint handles 10x your current traffic before we ship.
We ship complete observability out of the box: Datadog dashboards, PagerDuty alerts, and structured logging via ELK stack. Your team gets Grafana dashboards for real-time monitoring of throughput, error rates, and latency percentiles.
Generic Dev Shop vs Top Scalable Backend Consultants
Most dev shops build monolithic backends that break under load. IRPR designs for scale from the first line of code.
Generic agencies often use shared hosting, skip load testing, and deliver spaghetti code. You end up with a system that costs twice as much to rewrite after the first traffic spike.
IRPR uses infrastructure as code, stateless services, and horizontal scaling patterns. Every backend passes a 48-hour soak test with simulated peak traffic before we hand it over.
- Shared hosting or single instance
- No load testing in the contract
- Monolithic code that fails on one bad query
- No monitoring beyond basic health checks
- Hourly billing with scope creep
- No CI/CD until you ask for it
- Multi-region AWS/GCP with Terraform
- k6 load tests at 10x your expected peak
- Stateless microservices with auto-scaling
- Datadog + PagerDuty + ELK out of the box
- Fixed price, no surprises
- GitHub Actions CI/CD from day one
Our 4-Phase Approach to Scalable Backend Development
We follow a structured process that turns your requirements into a production-ready backend in 12 weeks.
The Roadmap phase (week 1-2) produces a fixed-price quote, API specifications in OpenAPI 3.0, and an infrastructure diagram. You approve everything before we write a line of code.
The Product phase (weeks 3-10) builds all services, sets up CI/CD, and runs continuous load tests. We ship code every sprint and demo progress weekly.
What Ships With Every Scalable Backend Project
Every delivery includes everything your team needs to operate and scale the backend independently.
We treat documentation as code. Every endpoint is documented in a Postman collection, every infrastructure decision is recorded in the architecture decision log (ADL), and every runbook is tested during the handover week.
You own everything from day one. There are no licenses, no ongoing fees, and no lock-in. Your team can modify, deploy, and scale the system without contacting us.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions or CircleCI
- Terraform infrastructure scripts for AWS or GCP
- OpenAPI 3.0 specification with Postman collection
- Datadog dashboards with p50/p95/p99 latency metrics
- PagerDuty escalation policies configured
- k6 load test scripts and results report
- Architecture decision log (ADL) with 15+ decisions
What we ship in this practice.
Multi-Tenant SaaS Backend Rebuild
A Series A SaaS company was hitting API rate limits with 500 concurrent users. IRPR rebuilt the backend with AWS Lambda + API Gateway + DynamoDB and implemented tenant isolation. The new system handles 5,000 concurrent users without throttling, and the team reduced p95 latency from 800ms to 120ms.
Real-Time Payment Processing Pipeline
A fintech startup needed a PCI-DSS compliant backend to process 10,000 transactions per minute. We built an event-driven pipeline using AWS SQS + Lambda + Aurora PostgreSQL with encryption at rest. The system processes 15,000 TPS at peak with zero data loss and passes SAQ-D audit in week 10.
HIPAA-Compliant Telemedicine Backend
A healthcare platform needed a scalable backend for video consultations and patient records. IRPR deployed Kubernetes on AWS EKS with Istio for mTLS and Redis for session caching. The system handles 2,000 concurrent video streams with sub-200ms latency and passed a third-party HIPAA audit within 2 weeks of go-live.
Global eCommerce Checkout Infrastructure
An ecommerce brand expanding to 10 countries needed a multi-region backend for checkout, inventory, and shipping. We used CockroachDB for global data replication and GraphQL federation via Apollo. Orders are processed in under 500ms across regions, and the system scaled to 50,000 orders per hour on Black Friday without a single timeout.
IoT Data Ingestion Platform
A manufacturing company needed to ingest sensor data from 50,000 devices every minute. IRPR built a pipeline with Kinesis + Lambda + TimescaleDB (PostgreSQL extension). The system processes 1 million events per second with 99.95% uptime and automatically scales during production surges.
Real-Time Analytics Dashboard Backend
A media company wanted a backend for live audience analytics with under 1 second refresh. We implemented a streaming pipeline using Apache Flink + Elasticsearch + Redis. The system ingests 200,000 events per second and serves dashboard queries with p99 latency under 300ms, replacing a previous solution that took 5 minutes to refresh.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
Senior Engineers Only
Our smallest team has 2 senior engineers averaging 12 years of backend experience each. No junior developers, no offshoring, no knowledge gaps. Your project is led by someone who has scaled systems to 100 million requests per day.
12-Week Delivery Guarantee
We ship production-ready backends in 12 calendar weeks. The Roadmap phase locks the scope, and we hit that date 98% of the time. If we miss, you get 2 weeks of post-launch support free.
Full Code Ownership
You own all source code, infrastructure scripts, and documentation from day one. There are no licenses, no ongoing royalties, and no lock-in. Your team can deploy independently after handover.
Load Testing Built Into Every Project
We use k6 to simulate 10x your expected peak traffic before we ship. Every endpoint must maintain sub-100ms p99 latency under load. The load test report is a deliverable you receive with the code.
Production Monitoring Out of the Box
Every backend ships with Datadog dashboards, PagerDuty alerting, and structured logging via ELK stack. Your ops team can see p50/p95/p99 latency, error rates, and throughput from the first deployment.
