Best Custom Backend Development ServicesBackend Development
We build production-grade backends with Node.js, Go, and Python. Senior engineers only, fixed pricing, and 8-12 week delivery.
IRPR delivers the best custom backend development services using Node.js, Go, Python, and PostgreSQL. We build RESTful APIs, GraphQL endpoints, microservices, and event-driven architectures that handle millions of requests per day.
Our backend projects ship in 8 to 12 weeks with fixed pricing from $80K to $250K. Every backend is built for compliance: HIPAA for healthcare, PCI-DSS for fintech, and SOC 2 for SaaS platforms.
CTOs hire us to replace legacy monoliths with scalable microservices. Startup founders use us to build their first production backend in under 3 months. Product managers come to us when their in-house team lacks the seniority to design high-throughput systems.
Types of software we ship.
REST API development
Build stateless RESTful APIs with Node.js and Express. Includes OpenAPI documentation, rate limiting, and JWT auth.
GraphQL API development
Implement GraphQL endpoints using Apollo Server or Yoga. Schema-first design with resolvers optimized for N+1 queries.
Microservices architecture
Decompose monoliths into Dockerized microservices with message queues (RabbitMQ, Kafka) and service discovery via Consul.
Serverless backend development
Build event-driven backends on AWS Lambda or Cloud Functions. Use DynamoDB or Firestore for serverless databases.
Real-time backend development
Implement WebSocket servers with Socket.io or Pusher. Supports live chat, notifications, and collaborative editing.
Backend for mobile apps

Backend for AI/ML applications
Create inference APIs with FastAPI or Flask. Integrate OpenAI, Hugging Face, or custom models with Redis caching for low latency.
We build for every business type.
SaaS platforms
Healthcare applications
Fintech applications
Ecommerce and retail
Real estate platforms
Why Choose Our Custom Backend Development Services
We deliver backend systems that run in production for years without rewrites.
Our backend developers average 10+ years of experience. We use Node.js, Go, Python, and PostgreSQL to build systems that handle 10,000+ requests per second. Every project includes automated load testing with k6 and CI/CD pipelines on GitHub Actions.
We have shipped backends for 200+ products across 50 countries. Our on-time delivery rate is 98%. Production systems we build maintain 99.9% uptime with AWS or GCP infrastructure. We include Sentry error tracking and Datadog monitoring in every deployment.
Generic Dev Shop vs IRPR: The Backend Development Difference
Most agencies deliver backends that need rewrites within a year. We do not.
Generic shops assign junior developers to your project. They write monolithic code with no tests, skip load testing, and deliver unsecured APIs. You pay hourly with no cap and get a system that breaks under scale.
IRPR assigns senior engineers only. We write typed code in TypeScript or Go, enforce 90%+ test coverage, and run load tests before deployment. You get a fixed price quote in week 2 and full code ownership.
- Junior developers with 1-2 years experience
- No automated tests or CI/CD
- Hourly billing with no cap
- Monolithic code that scales poorly
- No compliance documentation (HIPAA, PCI)
- You do not own the code after payment
- Senior engineers with 10+ years each
- 90%+ test coverage, CI/CD on GitHub Actions
- Fixed price quote in Roadmap phase (week 2)
- Microservices or modular monolith with documented APIs
- Full compliance: HIPAA, PCI-DSS, SOC 2, FERPA
- You own all source code and IP
Our Backend Development Process in 4 Phases
From idea to production in 8-12 weeks with a clear roadmap.
Every project follows our Idea-Roadmap-Product-Release framework. We ship working software every 2 weeks. No hidden phases, no surprise delays.
You get a fixed price quote after the Roadmap phase. Changes are managed through a change order process that keeps the project on track.
What Ships with Every Backend Development Project
Every deliverable is production-ready and fully documented.
We do not hand over a zip file. You get a fully deployed system with monitoring, CI/CD, and documentation. Your team can take over maintenance immediately.
All source code is in your private GitHub repository. We set up your cloud infrastructure (AWS, GCP, or Azure) and configure it for your expected traffic.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Deployed staging environment on AWS or GCP
- Production deployment with rollback script
- API documentation (OpenAPI or GraphQL schema)
- Database schema migration scripts
- Load test results from k6 (10,000+ requests)
- Sentry error tracking and Datadog monitoring
- Security scan report (OWASP top 10)
- 30-day production warranty with SLA
What we ship in this practice.
Multi-Tenant SaaS Backend for a B2B Analytics Platform
Built a multi-tenant backend with Node.js, PostgreSQL, and Redis. Each tenant gets isolated data with row-level security. Reduced onboarding time from 2 weeks to 2 days. Handles 500+ tenants with sub-100ms API response times.

Why teams hire us.
Senior engineers only, no juniors
Every backend developer on your project has 10+ years of experience. We do not staff juniors. You get a lead engineer who has shipped production systems at scale.
Fixed price, not hourly
After the Roadmap phase (week 2), you get a fixed price quote. No hourly billing, no surprise invoices, no scope creep charges. The price we quote is the price you pay.
8-12 week delivery
We ship production-ready backends in 8 to 12 weeks. Our average MVP timeline is 12 weeks. We have a 98% on-time delivery rate across 200+ projects.
Full code ownership
You own all source code, documentation, and IP from day one. We hand over the code in your private GitHub repo. No licensing fees, no vendor lock-in.
Compliance built in
We build backends that meet HIPAA, PCI-DSS, SOC 2, FERPA, and ISO 9001 standards. Compliance is not an afterthought. We design for it from the first sprint.
Production-grade monitoring
Every backend ships with Sentry error tracking, Datadog monitoring, and automated alerts. We set up dashboards for API latency, error rates, and database performance.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
