Senior Custom Backend Development ServicesBackend Development
We build production-ready backends with senior engineers only. Expect a fully functional MVP in 8-12 weeks at a fixed price.
IRPR provides senior custom backend development services for companies that need scalable, secure server-side software. We use Node.js, Python, Go, and Java with databases like PostgreSQL, MongoDB, and Redis to build APIs, microservices, and event-driven systems.
Every engagement delivers a working backend in 8-12 weeks with a fixed price of $80K-$250K depending on scope. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box. Our engineers work in your time zone overlap hours from New York to Los Angeles.
We work with CTOs who need to ship a SaaS MVP without a full-time team, startup founders who need a production-ready backend before their next funding round, and engineering leads who need to scale an existing system from 1,000 to 100,000 users.
Types of software we ship.

Why senior custom backend development services matter
A backend built by junior developers costs more in the long run through bugs, downtime, and rewrites.
IRPR assigns senior engineers only - people with 10+ years of experience building production systems. Every backend we deliver includes automated tests, CI/CD pipelines, and monitoring with Sentry and Datadog from day one.
Our fixed pricing ($80K-$250K) means you know the cost before we write a line of code. No hourly billing surprises. We've shipped backends for companies in New York, London, and Singapore that handle 10 million API calls per day.
The IRPR difference for backend development
Most dev shops overpromise and underdeliver. Here is what sets us apart.
Generic dev shops use offshore juniors who write fragile code. IRPR gives you a dedicated team of senior engineers who own the architecture and stay until production is stable.
We deliver the entire backend - not just code. You get infrastructure-as-code (Terraform), deployment playbooks, and 30 days of free production support after launch.
- Junior engineers on your project
- Hourly billing, no fixed price
- Delivered code only, no infrastructure
- No compliance checks
- 6-month average delivery
- No post-launch support
- Senior engineers only (10+ years)
- Fixed price from $80K to $250K
- Infrastructure (AWS/GCP) included
- HIPAA, PCI-DSS, SOC 2 out of box
- 8-12 week MVP delivery
- 30 days free production support
Our 4-step process for building your backend
We follow a clear process from idea to production. No guesswork.
Every senior custom backend development services engagement starts with a 2-week Roadmap phase where we define the architecture, database schema, and API contracts. You get a fixed quote before any development begins.
The Product phase builds the backend in 2-week sprints with daily standups and weekly demos. The Release phase deploys to production with automated rollbacks and health checks.
What ships with every backend
Every project includes a complete production-ready system, not just source code.
IRPR delivers the full package: source code in your GitHub repo, CI/CD pipelines on GitHub Actions, infrastructure on AWS or GCP via Terraform, and monitoring dashboards. You own everything from day one.
We also include API documentation (OpenAPI), integration tests with 80%+ coverage, and a runbook for your ops team. No hidden handoffs.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Infrastructure as code (Terraform) on AWS
- API documentation (OpenAPI 3.0)
- Automated test suite (80%+ coverage)
- Sentry error tracking and Datadog monitoring
- Deployment playbook and runbook
- 30 days production support and bug fixes
- Database migration scripts (Flyway/Sequelize)
- Rate limiting and DDoS protection
What we ship in this practice.
SaaS platform for property management
IRPR built a multi-tenant backend that processes rent payments and maintenance requests for 50,000 units. The system handles 2 million API calls per day using Node.js, PostgreSQL, and Stripe.
Telemedicine backend for a health startup
We delivered a HIPAA-compliant backend with video call scheduling, EHR integration, and medication management. The system reduced patient wait times by 40% using WebRTC and Twilio.
Payment processing backend for a fintech
Built a PCI-DSS Level 1 compliant system that processes 10,000 transactions per minute. Uses Java Spring Boot, Kafka, and Postgres. Achieved 99.99% uptime in the first year.
Inventory and order management for an ecommerce brand
IRPR built a real-time inventory sync between Shopify, Amazon, and a warehouse management system. Reduced overselling by 100% using Redis pub/sub and Node.js.
Real-time analytics backend for a media company
We built a data pipeline that ingests 5 million events per day from web and mobile apps. Uses Kafka for streaming, BigQuery for storage, and Express.js for the API.
API gateway for a logistics startup
IRPR developed a microservices gateway that routes tracking updates from carriers (FedEx, UPS, DHL) to a single customer-facing API. Handles 200,000 requests per hour on AWS Lambda.
Why teams hire us.
Senior engineers only, no juniors
Every member of your team has 10+ years of backend experience. We do not offshore to junior developers. You get a lead architect who owns the entire system.
Fixed price from the start
IRPR gives you a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices. Our average project costs $80K to $250K.
We ship in 8-12 weeks
Your backend reaches production in 8-12 weeks, not 6 months. We have a 98% on-time delivery rate across 200+ products.
Compliance built in, not bolted on
HIPAA, PCI-DSS, and SOC 2 controls are part of our standard build process. We implement encryption at rest (AES-256) and in transit (TLS 1.3) by default.
You own the full codebase
Every line of code, every config file, and every deployment script belongs to you. There is no license fee, no code escrow, no vendor lock-in.
We support production after launch
Every project includes 30 days of free production support. We fix bugs, tune performance, and help with the first deployment. After that, you can extend support month by month.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
