Senior Scalable Backend Development ServicesScalable Backend
Senior engineers build backend systems that handle 10x traffic growth. Fixed price. 8-12 week delivery.
IRPR builds senior scalable backend development services using Node.js, Python, Go, PostgreSQL, Redis, Kafka, and cloud-native tools on AWS, GCP, and Azure. Our senior engineers design systems that scale from 100 to 10 million users without breaking.
Every project ships in 8-12 weeks with a fixed price between $80,000 and $250,000. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get production-ready code with monitoring, CI/CD, and error tracking from day one.
We work with SaaS founders who need a scalable backend before their Series A, CTOs migrating from monolithic to microservices, enterprise teams building real-time APIs, and healthcare platforms requiring HIPAA-compliant data pipelines.

Why senior engineers matter for scalable backend development
Senior engineers write code that doesn't break at 10x traffic. They choose the right database, caching, and queueing from the start.
IRPR only hires engineers with 8+ years of experience. Every backend architect has shipped production systems handling over 1 million requests per second. Our team avoids junior mistakes like missing indexes, unoptimized queries, or single points of failure.
A senior scalable backend development project with IRPR starts with a deep architecture review. We choose tech like PostgreSQL 16, Redis 7, and Apache Kafka 3.6. We benchmark your critical paths and set up load testing with k6 before writing a line of code.
How IRPR differs from generic development shops
Most agencies use junior developers and bill hourly. IRPR assigns a senior backend architect and gives you a fixed price.
Generic dev shops often outsource to junior teams who copy code from Stack Overflow. They skip load testing, ignore security, and deliver code that fails under pressure. You pay hourly and watch scope creep.
IRPR assigns a lead senior engineer who owns your architecture. Every project includes automated deployment via Terraform CI/CD on GitHub Actions, Sentry error monitoring, and New Relic performance tracking. You pay once and own everything.
- Junior developers with 1-2 years experience
- Hourly billing with no cap ($150-$300/hr)
- No load testing – code goes live untested
- No CI/CD pipeline – manual deploys
- Third-party IP reused without credit
- Scope creep – 6 months becomes 12
- Senior engineers with 8+ years
- Fixed price from $80K to $250K
- Load testing with k6 at every milestone
- CI/CD with GitHub Actions, Docker, ECS
- Clean code with full documentation
- 8-12 weeks guaranteed, on time 98%
Our process for building a scalable backend
We follow four phases: discovery, architecture, build, and release. Each phase has a clear deliverable and a go/no-go checkpoint.
In the discovery phase (week 1), our senior engineer interviews your team, reviews your current infrastructure, and identifies bottlenecks. We produce a 10-page technical specification with database schema, API routes, and deployment plan.
The architecture phase (weeks 2-3) delivers a detailed AWS CloudFormation template, a GitHub repo with CI/CD, and a load test report. You approve before we write any production code.
What ships with every scalable backend project
You get more than code. Every project includes infrastructure, monitoring, and documentation so your team can maintain it.
Our senior engineers ship a complete package. You get source code in your repository, a CI/CD pipeline that builds and deploys automatically, and monitoring dashboards that alert you before users notice a problem.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions, Docker, and ECS
- Infrastructure as code (Terraform or CloudFormation)
- Sentry error tracking with alerts
- New Relic performance monitoring
- PostgreSQL database with automated backups
- Redis cache cluster configured for your data
- API documentation with Swagger/OpenAPI
- Load test report using k6 (10,000 virtual users)
- Production deployment guide and runbook
What we ship in this practice.
Multi-tenant SaaS backend for a CRM startup
Built a Node.js + PostgreSQL backend with row-level security for 500+ tenants. Reduced query latency by 60%. Deployed on AWS ECS with auto-scaling. Stack: NestJS, TypeORM, PostgreSQL 16, Redis, AWS ECS.
HIPAA-compliant data pipeline for a telemedicine platform
Designed an event-driven system using Apache Kafka to ingest patient vitals from 10,000 devices per minute. Achieved 99.99% uptime with multi-region failover. Stack: Python, Kafka, MongoDB, AWS KMS.
Payment processing microservices for a fintech startup

Why teams hire us.
All senior engineers, no juniors
Every backend architect at IRPR has 8+ years of production experience. We never staff juniors on your project. This means fewer bugs, faster delivery, and code that scales.
Fixed price, no hourly surprises
You get a fixed quote in week 2 after the Roadmap phase. Typical budgets for senior scalable backend development services range from $80K to $250K. No hourly billing, no scope creep charges.
8-12 week delivery guaranteed
Our sprint-based process delivers a production-ready backend in 8-12 weeks. We ship on time 98% of the time because we over-invest in planning and cut features that don't matter.
Full code ownership and clean handoff
You own 100% of the source code, infrastructure scripts, and documentation. No lock-in. We provide a runbook and a 2-week knowledge transfer session after release.
Compliance built-in from day one
We support HIPAA, PCI-DSS, SOC 2, and FERPA. We log all access, encrypt data at rest and in transit, and provide audit trails out of the box.
Global team, async-first work
Our senior engineers work across 12 time zones. You get daily standups via Slack and a project dashboard. We overlap at least 4 hours with your team for real-time collaboration.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
