Senior Scalable Backend Development FirmScalable Backend
We build backend systems that handle 100x traffic growth without rewrites. Fixed price, 8-12 week delivery, senior engineers only.
IRPR is a senior scalable backend development firm. We assign only engineers with 8+ years of experience in distributed systems, microservices, and high-traffic APIs. Our tech stack includes Node.js, Go, Python, PostgreSQL, Redis, Kafka, and Kubernetes on AWS or GCP.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle SOC 2, HIPAA, and PCI-DSS compliance. You get production-ready code, CI/CD pipelines on GitHub Actions, and Datadog monitoring from day one.
Founders with SaaS platforms on AWS hire us to avoid downtime during funding rounds. CTOs migrating from monoliths to microservices use us to reduce deployment friction. Product owners at logistics and fintech companies hire us to build APIs that scale to millions of requests per day without rewrites.
Types of software we ship.
High-traffic API development
Build RESTful or GraphQL APIs using Express or Fastify, handling 50K+ requests per second with Redis caching.
Microservices architecture
Decompose monoliths into loosely coupled services with Kubernetes orchestration and gRPC communication.
Real-time event streaming
Implement Apache Kafka or RabbitMQ for real-time order processing, live notifications, and log aggregation.
Serverless backend systems

Why a senior scalable backend development firm matters for your growth
One bad query can take down a system during a 10x user spike. IRPR builds backends that survive viral moments.
When a fintech client hit 2 million requests per minute during a Black Friday sale, their old backend collapsed in 30 seconds. IRPR rebuilt their API layer with Go microservices and Redis caching. Uptime stayed at 99.99% during the next 4x traffic spike.
A SaaS startup we worked with raised a Series A round 3 months early because their backend scaled from 10K to 500K daily active users without a single outage. The investors cited the backend architecture as the reason for their confidence. That system was built in 11 weeks for $180K fixed price.
How IRPR differs from a typical dev shop
Most agencies assign junior devs to backend work. IRPR assigns senior engineers only.
A typical dev shop says 'we do backend' but assigns a developer with 2 years of experience to your Node.js API. IRPR assigns engineers with 8-15 years of experience in distributed systems. We do not outsource to junior talent or offshore teams.
We also give you a fixed price upfront. No hourly billing. No scope creep surprises. You pay exactly what we quote in the Roadmap phase (week 2). If the project takes longer, we pay the overrun, not you.
- Assigns junior or mid-level developers
- Bills hourly with no cap on total cost
- No SLA on uptime or response times
- Uses a single cloud provider with no multi-region setup
- Fails during traffic spikes due to monolithic design
- Writes untested code with no CI/CD pipeline
- Assigns senior engineers only (8+ years experience)
- Fixed price from Roadmap phase - no hourly billing
- 99.9% uptime SLA with Datadog monitoring
- Multi-region deployment on AWS or GCP using Terraform
- Built with microservices and auto-scaling from day one
- CI/CD pipeline on GitHub Actions with Sentry error tracking
Our 4-phase backend development process
Every project follows the same four-phase framework. No ambiguity. No surprises.
Phase 1 (Idea) is a 2-day deep dive where we map your system's data flow, API surface, and scaling requirements. We identify bottlenecks before they exist. Phase 2 (Roadmap) produces a fixed-scope, fixed-price plan with a 12-week timeline.
Phase 3 (Product) is where we write production code. We build the API, database, caching layer, and CI/CD pipeline. Everything runs in staging within week 6. Phase 4 (Release) deploys to production with monitoring, alerts, and a one-year warranty.
What ships when you build a backend with IRPR
You get more than code. You get a complete production system.
We ship everything required to run a backend at scale in production. Our checklist includes the API gateway, database schema, caching layer, CI/CD, monitoring, and documentation. You own all code and infrastructure assets from day one.
- Source code in your private GitHub repo with full commit history
- CI/CD pipeline on GitHub Actions with automated tests and deployments
- Sentry error tracking and Datadog monitoring dashboard
- PostgreSQL or CockroachDB schema with migrations and indexing
- Redis caching layer for read-heavy endpoints
- Kubernetes deployment manifests with auto-scaling policies
- API documentation auto-generated from OpenAPI specs
- Load test report from k6 showing performance under 100x target traffic
- One-year warranty covering bugs and performance regressions
What we ship in this practice.
Payment gateway backend with 99.99% uptime
Built a PCI-DSS compliant payment processing system handling 5,000 transactions per second. Used Go, CockroachDB, and Kafka. Reduced transaction latency from 400ms to 45ms. Industry: Fintech.
Multi-tenant SaaS API with 100x scaling
Designed a tenant-isolated API for a B2B SaaS platform serving 50,000 businesses. Used Node.js, PostgreSQL, and Redis. Cut onboarding time from 2 weeks to 4 hours. Industry: SaaS.
Real-time order engine for a logistics startup
Replaced a batch-processing system with a real-time event-driven backend using Apache Kafka and MongoDB. Order processing dropped from 5 minutes to 3 seconds. Industry: Logistics.
HIPAA-compliant backend for a telehealth app
Built a compliant patient data exchange with AWS HealthLake, FHIR APIs, and end-to-end encryption. Handled 1 million patient records with sub-second queries. Industry: Healthcare.
Inventory management backend for an ecommerce brand
Created a real-time inventory sync service for a brand selling across Shopify, Amazon, and their own site. Used PostgreSQL, RabbitMQ, and GraphQL. Reduced overselling by 95%. Industry: Ecommerce.
Real-time recommendation engine for a media platform
Built a streaming recommendation backend using Redis, Spark, and TensorFlow serving. Increased user session time by 35%. Handled 20 million events per day. Industry: Media.
Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If the project takes longer, IRPR covers the overrun.
Senior engineers only, no juniors
We assign only engineers with 8+ years of experience in distributed systems. No junior developers, no offshore teams, no project management overhead. You talk directly to the lead engineer.
Production-ready from week 1
We ship CI/CD pipelines, Sentry error tracking, and Datadog monitoring with the first deployment. You see real performance metrics and error logs in staging by week 6.
Compliance built in, not bolted on
We handle SOC 2, HIPAA, PCI-DSS, and GDPR compliance as part of the architecture. We include encryption, audit logs, and access controls from day one, not as a retroactive add-on.
12-week delivery, not 6 months
Our average project ships in 12 weeks. We run 2-week sprints with daily demos. You can test code in staging by week 6 and go live by week 12.
Full ownership and no lock-in
You own all source code, infrastructure scripts, and monitoring dashboards. We use open-source tools and standard cloud services. You can switch providers or take the code in-house without penalty.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
