Top Custom Backend Development CompanyCustom Backend
We build backend systems that scale to millions of users. 200+ products shipped with Node.js, Python, Go, and Rust.
IRPR is a top custom backend development company. We design and build backend architectures using Node.js, Python, Go, and Rust. Every system includes a REST or GraphQL API, a relational or NoSQL database, and cloud infrastructure on AWS, GCP, or Azure.
We deliver a production-ready backend in 12 to 14 weeks. Pricing starts at $80K and goes to $250K depending on complexity. All code is fully owned by you. We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance.
CTOs hire IRPR to replace a legacy monolith with microservices. Startup founders hire us to build a scalable MVP from scratch. Product managers hire us to add real-time features like WebSockets or push notifications. Engineering leads hire us to migrate databases or optimize query performance.
Types of software we ship.
REST API development
Build a stateless REST API with Express.js or FastAPI. Handles 10,000+ requests per second with Redis caching.
GraphQL API development
Build a GraphQL API with Apollo Server or Hasura. Reduces overfetching and speeds up mobile app data loading by 40%.
Microservices architecture
Decompose a monolith into Dockerized microservices. Each service scales independently on Kubernetes.
Real-time backend with WebSockets
Add real-time capabilities using Socket.IO or WebSocket. Supports chat, live notifications, and collaboration tools.
Database design and migration
Design normalized SQL schemas or migrate from MongoDB to PostgreSQL. Zero-downtime migrations using Flyway or Alembic.
Serverless backend
Build event-driven backends on AWS Lambda or Google Cloud Functions. Pay per execution, zero server management.
Backend for mobile apps
Build a dedicated backend for iOS and Android apps. Includes authentication, push notifications, and file uploads to S3.
Third-party API integration
Integrate with Stripe, Twilio, Salesforce, or HubSpot. Handles rate limiting, webhooks, and OAuth 2.0 flows.
We build for every business type.
Healthcare and fintech
SaaS and ecommerce
Real estate and logistics
Media and travel

Why you need a top custom backend development company
A custom backend handles your exact business logic, scales with your users, and integrates with your existing tools.
Off-the-shelf backends force you into predefined workflows. A custom backend built by IRPR fits your data model, your API contracts, and your compliance needs. We write code in Node.js, Python, Go, or Rust - whichever matches your performance and team requirements.
Every backend we build includes automated tests (Jest, pytest, or Go test), a CI/CD pipeline on GitHub Actions, and monitoring with Datadog or Sentry. We deploy on your AWS, GCP, or Azure account so you own the infrastructure from day one.
IRPR vs generic backend shops
Generic shops write code. IRPR ships production backends that your team owns and operates from day one.
Many backend agencies deliver spaghetti code with no tests and no deployment scripts. You get a tarball and a bill. With IRPR you get a tested, documented, containerized backend running in your cloud account.
We follow a structured process: Idea (week 1), Roadmap (week 2), Product (weeks 3-10), Release (weeks 11-12). Every phase has a deliverable you can review and approve.
- No upfront architecture review
- No automated tests
- No CI/CD pipeline
- Deploys on their account, not yours
- No monitoring or error tracking
- Hourly billing with no cap
- Architecture document in week 2
- 100% test coverage on critical paths
- CI/CD on GitHub Actions from day one
- Deploys on your AWS/GCP/Azure account
- Sentry + Datadog monitoring included
- Fixed price, no surprises
How we build your backend
We follow a four-phase process that turns your idea into a running backend in 12 weeks.
Phase 1 is Discovery. We map your data model, user flows, and API endpoints. Phase 2 is Setup. We spin up your cloud infrastructure (VPC, RDS, ECS), initialize the repo, and configure the CI/CD pipeline.
Phase 3 is Development. We build the API layer, database, and integrations in 6-8 sprints. Phase 4 is Deployment and launch. We run load tests, set up monitoring, and hand over the repo with full documentation.
What ships with your backend
We hand over a complete production system, not just code.
Every backend includes source code, infrastructure-as-code, CI/CD pipeline, and monitoring. You get full ownership of everything we build, and we include a 30-day post-launch support window.
We also provide a technical handover document and a walkthrough call with your engineering team. The code is yours. The passwords are yours. The cloud account is yours.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Dockerized services with docker-compose
- Database schema with migrations
- API documentation (OpenAPI or GraphQL schema)
- Sentry error tracking
- Datadog monitoring dashboard
- Load test results (k6 or Artillery)
- Cloud infrastructure on your account using Terraform
- 30-day post-launch support
What we ship in this practice.
HIPAA-compliant telehealth backend
Built a patient-provider appointment backend with real-time video signaling. Used Node.js, PostgreSQL, Twilio, and AWS HealthLake. Reduced appointment no-show rates by 25%.
PCI-DSS-compliant payment API
Built a tokenization layer for a fintech startup. Used Python, FastAPI, Stripe, and HashiCorp Vault. Handled $2M in monthly transactions within the first quarter.
Multi-tenant SaaS backend
Built a subscription management backend with user isolation per tenant. Used Go, PostgreSQL, and Stripe. Scaled from 10 to 500 tenants in 6 months.
Ecommerce product search API
Built a full-text search backend with faceted filtering. Used Node.js, Elasticsearch, and Redis. Reduced search response time from 3 seconds to 200 milliseconds.
Real estate MLS integration backend
Built a data pipeline that ingests MLS listings from 5 regional providers. Used Python, PostgreSQL, and Apache Kafka. Synced 50,000+ listings daily with 99.9% accuracy.
IoT sensor data backend
Built a time-series data pipeline for a manufacturing client. Used Go, InfluxDB, and MQTT. Processed 10,000 sensor readings per second with sub-50ms latency.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Full code ownership
We write code in your repository from day one. You own every line. There are no licensing fees or platform lock-ins.
Senior engineers only
Every developer on your project has 8+ years of backend experience. We do not outsource to junior developers or agencies.
Production-ready from launch
Your backend ships with monitoring, error tracking, CI/CD, and load-tested endpoints. It is ready for real users on day one.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture. We do not bolt it on after the fact.
12-week delivery guarantee
We deliver a working MVP in 12 to 14 weeks. If we miss the deadline, you pay a reduced rate until we deliver.
