Expert Custom Backend Development AgencyBackend Development
Build backend systems that handle millions of requests per day. 200+ products shipped in 12 weeks or less.
IRPR builds custom backend systems using Node.js, Python, Go, PostgreSQL, MongoDB, Kafka, and Docker. We design APIs, microservices, and event-driven architectures that scale to millions of users.
Every project ships in 12 to 14 weeks with a fixed price between $80,000 and $250,000. Our systems meet SOC 2, HIPAA, and PCI DSS compliance standards out of the box.
CTOs scaling SaaS platforms hire us for high-throughput APIs. Fintech founders need PCI-compliant payment backends. Healthcare startups require HIPAA-ready data pipelines. Ecommerce brands need real-time inventory systems.
Types of software we ship.
REST API Development
Build stateless REST APIs with Express.js or FastAPI. Includes OpenAPI docs, rate limiting, and JWT auth.
GraphQL API Development
Create flexible GraphQL APIs using Apollo Server or Yoga. Supports federation, caching, and real-time subscriptions.
Microservices Architecture

What We Deliver in Every Backend Project
Every backend system we build ships with production-grade infrastructure and documentation.
IRPR has delivered over 200 backend projects across 50 countries. Our average timeline is 12 weeks from kickoff to deployment. We maintain a 98% on-time delivery rate.
All systems are built with Docker containers, CI/CD pipelines on GitHub Actions, and monitoring via Datadog or Sentry. We include load testing and security audits before launch.
Why IRPR Beats Generic Development Shops
Generic shops bill hourly and deliver late. IRPR gives you a fixed price and a real deadline.
Most agencies start with a vague estimate and charge for every extra hour. You never know the final cost until the project ends.
IRPR works differently. We define the full scope in a 2-week Roadmap phase, then lock the price. No hourly billing, no surprise invoices, no scope creep.
- Hourly billing with no cap
- Unclear timelines that slip
- No compliance expertise (HIPAA, PCI, SOC 2)
- Code ownership often unclear
- No CI/CD or monitoring setup
- You manage project management yourself
- Fixed price locked after Roadmap
- 12-week delivery guarantee
- Built-in SOC 2, HIPAA, PCI compliance
- Full code ownership in your repo
- CI/CD pipeline with GitHub Actions and Sentry
- Dedicated project manager included
Our Backend Development Process in 4 Phases
We follow a structured process from idea to production deployment.
Each phase has clear deliverables and milestones. You know exactly what ships each week.
The process takes 12 weeks on average. Complex enterprise systems may need 14 weeks.
What Ships with Every Backend Project
Every deliverable is production-ready and fully documented.
You own everything. Source code, infrastructure code, and monitoring dashboards are all transferred to your accounts.
We also include a 30-day post-launch support window for any issues.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog monitoring dashboard
- API documentation (Swagger/OpenAPI)
- Load testing report (k6 or Artillery)
- Security audit report (OWASP top 10)
- Docker Compose or Kubernetes manifests
- Database schema and migration scripts
- Post-launch support for 30 days
What we ship in this practice.
Payment Processing API for Fintech
Built a PCI-compliant payment API using Go and PostgreSQL. Handles 5,000 transactions per second with 99.99% uptime. Reduced transaction failure rate by 60%.
Real-Time Inventory System for Ecommerce
Developed an event-driven inventory sync using Kafka and Node.js. Processes 10,000 updates per second across 50 warehouses. Eliminated overselling by 100%.
HIPAA-Compliant Patient Data Pipeline
Created a healthcare data pipeline with Python, AWS Lambda, and FHIR APIs. Transfers 2 million patient records daily with end-to-end encryption. Reduced data latency from 24 hours to 5 minutes.
Multi-Tenant SaaS Backend for CRM
Designed a multi-tenant microservices backend with Django and PostgreSQL. Supports 10,000 tenants with isolated data per tenant. Scaled from 0 to 500,000 users in 6 months.
Real-Time Analytics Dashboard Backend
Built a streaming analytics backend using Apache Flink and Redis. Ingests 100,000 events per second and serves dashboard queries in under 100ms. Used by a media company for live audience metrics.
Legacy System Migration for Logistics
Migrated a monolith to microservices using Node.js and AWS ECS. Cut deployment time from 4 hours to 5 minutes. Reduced infrastructure costs by 40%.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
Senior Engineers Only
Our team consists of senior engineers with 8+ years of experience. No junior developers, no outsourcing to low-cost regions.
Compliance Built In
We build SOC 2, HIPAA, and PCI DSS compliant systems from day one. No retrofitting compliance after launch.
12-Week Delivery Guarantee
We ship production-ready backend systems in 12 weeks on average. 98% of our projects finish on time.
Full Code Ownership
You own all source code, infrastructure code, and documentation. We transfer everything to your repos at the end of the project.
Post-Launch Support Included
Every project includes 30 days of post-launch support. We fix bugs, optimize performance, and help with any issues.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
