Experienced Custom Backend Development DevelopersBackend Development
We build production-grade backends with Node.js, Go, and PostgreSQL. Your MVP ships in 12 weeks at a fixed price.
IRPR builds custom backends using Node.js, Go, Python, PostgreSQL, Redis, and AWS Lambda. We design RESTful APIs, GraphQL schemas, and event-driven microservices that handle millions of requests per day.
Every project ships in 8 to 12 weeks with a fixed price between $80K and $250K. We include CI/CD on GitHub Actions, monitoring with Datadog, and error tracking with Sentry — all compliant with HIPAA, PCI-DSS, or SOC 2.
Startup CTOs hire us to build a backend that can scale to 10K users. Enterprise architects need a migration from legacy APIs to microservices. Product managers at SaaS companies want a GraphQL layer that reduces mobile app load times by 40%.
Types of software we ship.
REST API Development
Build secure REST APIs with Express.js, FastAPI, or Go Gin. Includes rate limiting, JWT auth, and OpenAPI docs.
GraphQL API Development
GraphQL backends with Apollo Server, Prisma ORM, and resolver-level caching. Reduces over-fetching by 60%.
Microservices Architecture
Event-driven microservices on Kubernetes, RabbitMQ, and Docker. Each service scales independently with its own database.
Real-Time Backend (WebSocket)
WebSocket servers in Node.js or Python with Redis pub/sub. Powers live dashboards and chat apps with sub-100ms latency.
Database Design & Optimization

Serverless Backend (AWS Lambda)
Serverless functions with AWS Lambda, API Gateway, and DynamoDB. Zero cold starts using provisioned concurrency.
Authentication & Authorization System
Auth0, Firebase Auth, or custom OAuth2.0 with role-based access control (RBAC). Supports SAML and SSO for enterprises.
Backend for Mobile Apps
Mobile-optimized backends with Firebase Cloud Functions, MongoDB Atlas, and Firebase Realtime Database. Syncs offline data and handles push notifications.
We build for every business type.

Backend Development by the Numbers
IRPR has shipped over 200 custom backends across 50 countries with measurable results.
Our senior engineers use Node.js, Go, and Python to build backends that handle over 10 million API calls per month. We design databases with PostgreSQL replication and Redis caching to keep response times under 50ms.
Every project follows a strict 12-week timeline. We deliver with CI/CD pipelines on GitHub Actions, Datadog monitoring, and Sentry error tracking. Our on-time delivery rate is 98%, and production uptime averages 99.9%.
Why Generic Dev Shops Fail at Backend
Most agencies hide junior engineers and hourly billing — IRPR gives you a dedicated senior team and a fixed price.
Generic development shops assign junior developers who learn on your dime. They bill hourly, which means scope creep is their bonus. They skip CI/CD and monitoring, leaving you with a black box that crashes on launch day.
IRPR assigns a team of senior engineers (8+ years experience) from day one. We give you a fixed price after a 2-week Roadmap phase. You get source code, CI/CD pipelines, monitoring, and documentation — all in your own GitHub repo.
- Junior engineers doing backend work
- Hourly billing that rewards slow work
- No CI/CD pipeline delivered
- No monitoring or error tracking
- You do not own the source code
- Hidden scope creep charges
- Senior engineers with 8+ years experience
- Fixed price locked in at week 2
- CI/CD on GitHub Actions included
- Datadog monitoring + Sentry error tracking
- Full source code ownership
- Roadmap phase prevents scope creep
How We Build Your Backend in 12 Weeks
Our process is transparent: Idea, Roadmap, Product, Release — each phase has a fixed duration and deliverable.
Week 1: We map your data model, API endpoints, and third-party integrations. We pick the tech stack (Node.js, Go, Python, PostgreSQL, Redis, AWS, Docker).
Week 2-3: Roadmap phase produces a fixed price, a 12-week timeline, and a technical specification. You approve before any code is written.
What Ships With Every Backend Project
Every deliverable includes production-ready infrastructure, not just source code.
You get a complete system: source code in your private GitHub repo, a CI/CD pipeline with GitHub Actions that runs tests and deploys automatically, Datadog dashboards for latency and error rates, and Sentry for exception tracking.
We also include OpenAPI documentation (Swagger), a Docker Compose file for local development, and a 1-pager runbook. All compliance documentation (HIPAA, PCI-DSS, SOC 2) is prepared from day one.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Datadog monitoring dashboard
- Sentry error tracking
- OpenAPI (Swagger) documentation
- Docker Compose for local dev
- Production runbook (1 page)
- Load test results (k6 report)
- 30-day warranty on all code
- Dependency vulnerability scan (Snyk)
What we ship in this practice.
Backend for a Fintech Payment Gateway
Built a PCI-DSS compliant payment processing backend using Go, PostgreSQL, and Stripe Connect. Handled 50K transactions per hour with sub-200ms latency. Reduced manual reconciliation by 12 hours per week.
Healthcare Patient Portal API
Developed a HIPAA-compliant REST API for a telemedicine startup using Node.js, PostgreSQL, and AWS HealthLake. Served 100K patient records with end-to-end encryption. Reduced patient onboarding time from 15 minutes to 3 minutes.
SaaS Multi-Tenant Backend with Metered Billing
Designed a multi-tenant backend using Python, FastAPI, and AWS RDS. Integrated Stripe metered billing and usage quotas. Handled 10M API requests per day with 99.99% uptime.
Ecommerce Inventory Management Microservices
Replaced a monolithic inventory system with 8 microservices using Node.js, RabbitMQ, and MongoDB. Cut product update latency from 30 seconds to 1 second. Supported 5,000 SKUs with real-time sync to Shopify.
Real Estate MLS Integration Backend
Built a backend that ingests and normalizes MLS data from 10+ providers using Node.js, PostgreSQL, and Apache Kafka. Reduced data refresh time from 4 hours to 15 minutes. Enabled real-time property alerts.
EdTech Assessment Platform Backend
Created a FERPA-compliant backend for online assessments using Python, Postgres, and Redis. Supported 10,000 concurrent users during peak exam hours. Auto-graded 500+ responses per minute.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers, not juniors
IRPR only hires engineers with 8+ years of backend experience. You get a lead developer, a DevOps engineer, and a QA engineer — all senior. No junior developers learning on your time.
Full code ownership
You own the entire codebase from day one. We push code to your GitHub repo, not ours. No licensing fees, no vendor lock-in. You can take the code and run it anywhere.
Production-ready infrastructure
We ship CI/CD pipelines, monitoring with Datadog, error tracking with Sentry, and load testing reports. Your backend is ready for production on day one, not just a prototype.
Compliance built in
Every backend is designed for HIPAA, PCI-DSS, or SOC 2 from the start. We implement encryption at rest and in transit, audit logging, and role-based access control without extra cost.
12-week delivery guarantee
We build MVPs in 8 to 12 weeks. Our on-time rate is 98%. If we are late, you pay nothing for the extra weeks. This guarantee is written into every contract.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
