Experienced Scalable Backend Development ServicesBackend Development
We build backends that handle millions of requests without breaking. Senior engineers, fixed pricing, 12-14 week delivery.
IRPR provides experienced scalable backend development services for companies that need reliable, high-performance infrastructure. We use Node.js, Go, Python, PostgreSQL, Redis, and AWS to build backends that grow with your user base.
Every project ships in 12-14 weeks with a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance out of the box. Your team gets full source code, CI/CD pipelines, and monitoring dashboards.
We work with CTOs scaling their SaaS platform, fintech founders needing PCI-compliant APIs, healthcare startups requiring HIPAA audit trails, and ecommerce brands migrating to event-driven architectures.
Types of software we ship.
RESTful API development

Database architecture & scaling
Design and scale databases: PostgreSQL sharding, Redis caching, DynamoDB partitioning. Cut query times from 2s to 50ms.
Backend for mobile apps
Build mobile-optimized backends with Firebase or custom Node.js APIs. Handles push notifications, offline sync, and 100k+ concurrent users.
We build for every business type.
SaaS platforms
Fintech and payments
Healthcare and life sciences
Ecommerce and retail
Media and content
Why experienced scalable backend development matters
A backend that works at 100 users often breaks at 10,000. We design for scale from day one.
IRPR has built backends for products that grew from 0 to 1 million users in 12 months. We use horizontal scaling, caching layers, and database indexing to keep response times under 200ms. Our clients avoid costly rewrites because the architecture handles growth without redesign.
We also enforce security and compliance from the start. Every project includes encryption at rest and in transit, rate limiting, and audit logging. For fintech and healthcare clients, we add PCI-DSS Level 1 or HIPAA BAA coverage as part of the fixed price.
How we differ from generic development shops
Most agencies build backends that work today but fail tomorrow. We build for both.
Generic shops often use a single monolithic architecture because it's faster to prototype. They skip load testing, monitoring, and documentation. When traffic spikes, the backend crashes and the client pays for emergency fixes.
IRPR delivers a production-ready backend with load tests, auto-scaling, and full observability. Every project includes a stress test report showing the system handles 10x projected traffic. We also provide a runbook so your team can operate the system without us.
- Monolith that becomes tech debt
- No load testing until prod fails
- No monitoring or alerting
- Hourly billing with scope creep
- No compliance documentation
- Code dump with no runbook
- Microservices or modular monolith
- Load tested to 10x target traffic
- Datadog or Grafana dashboards
- Fixed price from Roadmap phase
- HIPAA/PCI/SOC 2 audit-ready
- Full runbook and CI/CD pipeline
Our backend development process
We follow a 4-phase process that turns your idea into a production backend in 12-14 weeks.
Phase 1 is the Roadmap: we define the architecture, data model, API contracts, and scalability targets. You get a fixed price and timeline. Phase 2 is Product: we build the backend iteratively, deploying to staging every 2 weeks.
Phase 3 is Release: we run load tests, security scans, and compliance checks. Then we deploy to production with blue-green deployment. Phase 4 is Handoff: we transfer all code, docs, and monitoring access. Your team takes over with full confidence.
What ships with every backend project
You get more than code. Every deliverable is designed to make your team self-sufficient.
We don't just hand over a GitHub repo. Every project includes a production-ready infrastructure, monitoring, and documentation. Your engineers can deploy changes on day one after handoff.
The checklist below is the minimum. For fintech and healthcare projects, we add compliance artifacts like SOC 2 Type II reports and HIPAA BAA documents.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Infrastructure as code with Terraform or Pulumi
- Auto-scaling configuration for AWS ECS or Kubernetes
- Load test report with Gatling or k6
- API documentation with Swagger or Postman
- Monitoring dashboards in Datadog or Grafana
- Error tracking with Sentry
- Runbook with incident response steps
- Security scan report with Snyk or OWASP ZAP
What we ship in this practice.
Real-time analytics backend for a B2B SaaS
Built an event-driven backend using Kafka, Flink, and PostgreSQL. Handles 500K events per hour with sub-second query times. Reduced dashboard load time from 8 seconds to 1.2 seconds.
PCI-compliant payment API for a fintech startup
Developed a Node.js API with tokenization and PCI-DSS Level 1 compliance. Integrated with Stripe and Plaid. Processed $2M in transactions in the first month with zero security incidents.
HIPAA-compliant backend for a telemedicine platform
Built a HIPAA-compliant backend using Go, PostgreSQL with encryption, and AWS HealthLake. Supports 10,000 concurrent video sessions. Passed HIPAA audit on first attempt.
Scalable order processing for an ecommerce marketplace
Designed a microservices backend with RabbitMQ, Redis, and Kubernetes. Processes 20,000 orders per hour with 99.95% uptime. Reduced order latency from 5 seconds to 300ms.
GraphQL backend for a mobile-first social platform
Implemented a GraphQL layer using Apollo Server with Redis caching. Supports 1 million daily active users with 150ms average response time. Reduced mobile data usage by 60%.
Serverless backend for a real estate MLS API
Built a serverless backend on AWS Lambda and DynamoDB. Handles 10,000 property searches per minute. Costs $200/month at launch and scales to $2000 at peak. Zero cold start issues using provisioned concurrency.
Why teams hire us.
Senior engineers only
Every IRPR engineer has 8+ years of backend experience. No juniors, no code monkeys. You talk directly to the person building your system.
Fixed price, no surprises
We give you a fixed price after the Roadmap phase (week 2). No hourly billing, no scope creep. The price stays the same even if we discover new requirements.
Production-ready from day one
Your backend ships with monitoring, CI/CD, load testing, and a runbook. Your team can deploy to production without us on week 14.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 as part of the build. No separate compliance project. Our backends pass audits on first try.
We have done this 200+ times
IRPR has shipped over 200 backend systems for clients in 50 countries. We know what breaks and what works. You get battle-tested patterns.
Full code ownership
You own every line of code. No licenses, no lock-in. We transfer all repos, infrastructure configs, and documentation at handoff.
