Why hire a custom backend development firm
A dedicated backend firm brings speed, compliance, and scalability to your project.
IRPR has shipped over 200 custom backend systems. Each project starts with a fixed-price Roadmap phase (week 2) so you know exactly what you are getting. We use automated testing and infrastructure as code to hit 99.9% uptime out of the gate.
Compliance is built in, not bolted on. We have delivered HIPAA-compliant healthcare backends and PCI-DSS compliant fintech systems. Every deployment includes Sentry error monitoring, Datadog metrics, and PagerDuty alerts.
How IRPR differs from other backend development firms
Most agencies bill hourly and deliver late. IRPR does not.
We quote a fixed price after the Roadmap phase. No hourly tracking, no time-sheet disputes. Senior engineers only - no junior staff, no outsourcing.
Every project includes CI/CD pipelines, automated tests, and monitoring from day one. Code is delivered to your GitHub repository. We never lock you in.
- Hourly billing with unpredictable costs
- Junior developers on your project
- No compliance expertise built in
- Code hidden until final payment
- No monitoring or alerting included
- Delays from scope creep and change orders
- Fixed price confirmed in week 2
- Senior engineers only (10+ years experience)
- HIPAA, PCI-DSS, SOC 2 compliance built in
- Full code ownership from day one
- Sentry, Datadog, PagerDuty included
- 8-12 week delivery, 98% on-time
Our process for custom backend development
From idea to production in four defined phases.
We use the Idea - Roadmap - Product - Release framework. Every phase delivers a tangible output that you can review and approve before moving forward.
No black box development. You see progress weekly in a shared dashboard with live demos and deployed environments.
What ships with every custom backend project
Every engagement includes production-grade infrastructure and tooling.
We do not hand over a zip file. You get a fully operational backend running in your AWS, GCP, or Azure account with CI/CD pipelines and monitoring.
All code is in your private GitHub repository under your organization. You control access and deployment.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions or CircleCI
- Infrastructure as code (Terraform or Pulumi)
- API documentation (OpenAPI or GraphQL schema)
- Sentry error tracking and performance monitoring
- Datadog dashboards for latency and error rates
- PagerDuty alerting for production incidents
- Automated test suite (unit, integration, load)
- Deployment runbook and architecture diagram
- Post-release support for 2 weeks
What we ship in this practice.
Real-time inventory sync for ecommerce
Built a microservices-based inventory system that syncs stock levels across Shopify, Amazon, and a warehouse management API. Reduced overselling by 100% and saved 15 hours per week in manual reconciliation. Stack: Node.js, PostgreSQL, Redis, Kafka.
HIPAA-compliant patient data API
Designed a RESTful API for a telehealth platform handling PHI. Included FHIR integration, role-based access control, and audit logging. Achieved HIPAA compliance in 10 weeks. Stack: Python FastAPI, PostgreSQL, AWS Lambda, Auth0.
Subscription billing engine for SaaS
Built a custom billing backend supporting tiered plans, usage metering, and dunning. Integrated Stripe and handled 50K+ active subscriptions. Reduced churn by 12% via automated retry logic. Stack: Ruby on Rails, PostgreSQL, Sidekiq, Stripe.
Payment processing pipeline for fintech
Created a PCI-DSS compliant transaction processing system with fraud detection rules and real-time ledger updates. Processed $2M in transactions in the first month. Stack: Go, PostgreSQL, Kafka, AWS ECS.
MLS data integration for real estate
Developed an API gateway that aggregates listings from 12 different MLS sources into a single searchable database. Reduced data latency from 24 hours to 5 minutes. Stack: Node.js, MongoDB, Elasticsearch, AWS Lambda.
Legacy migration to microservices for logistics
Migrated a monolithic order management system into 15 microservices with event-driven architecture. Cut deployment time from 4 hours to 10 minutes. Stack: Java Spring Boot, Kafka, PostgreSQL, Docker, Kubernetes.
