Why you need a senior backend development vendor
Generic shops deliver generic code. Senior engineers deliver production-ready systems that scale from day one.
A senior backend development vendor brings 10+ years of experience per engineer. IRPR engineers have built backends for 200+ products across 50 countries. They know how to avoid common pitfalls like N+1 queries, race conditions, and insufficient indexing.
When you hire IRPR, you get engineers who have done this before. They write code with observability in mind, add meaningful error handling, and set up monitoring with Sentry and Datadog. The result is a backend that stays up 99.9% of the time.
Generic dev shop vs senior backend development vendor
Not every vendor can deliver a production-grade backend. Here is what sets IRPR apart.
A generic dev shop might assign junior engineers who learn on your budget. They often skip testing, ignore security, and deliver code that breaks under load. You end up paying twice - once for the build and again for the rewrite.
IRPR assigns only senior engineers with 8+ years of backend experience. We write unit tests (over 80% coverage), use infrastructure as code, and include CI/CD pipelines. Every project includes a one-week warranty and 30 days of post-launch support.
- Junior or mid-level engineers
- No fixed timeline or price
- Code without tests or monitoring
- No security or compliance expertise
- Hourly billing with scope creep
- No post-launch support
- Senior engineers only (8+ years)
- Fixed price, 8-12 week delivery
- 80%+ test coverage, Sentry + Datadog
- HIPAA, SOC 2, PCI-DSS compliance ready
- Hourly billing zero, no scope creep
- 30 day free post-launch support
How IRPR builds your backend in 8-12 weeks
We follow a four-phase process that starts with a discovery call and ends with production code.
Every project begins with a 30-minute discovery call where we understand your requirements and constraints. Within 3 business days we propose a fixed price and timeline.
Once approved, we move into Roadmap (week 1-2), Product (weeks 3-10), and Release (week 11-12). Each phase includes a demo and sign-off before moving forward.
What ships with every backend project from IRPR
You get more than just code. Every project includes these deliverables by default.
Our goal is to make your team productive from day one. That means full documentation, runbooks, and infrastructure-as-code so you never hit a mystery.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- 80%+ unit test coverage with Jest or Mocha
- Sentry error tracking and Datadog monitoring
- Database migration scripts (PostgreSQL, MongoDB)
- Docker Compose and Kubernetes manifests
- API documentation with Postman or Swagger
- Architecture decision records (ADRs)
- Runbook for common operations
- 30-day post-launch support
What we ship in this practice.
Real-time notification service for a fintech startup
Built a notification microservice that processes 50,000 emails and 10,000 SMS per month. Reduced delivery latency from 30 seconds to under 2 seconds using Redis queues and Nodemailer. Tech stack: Node.js, Bull, Twilio, AWS SES.
HIPAA-compliant telemedicine backend
Developed API layer for a telehealth platform handling 1,000 daily appointments. Encrypted PHI in transit and at rest, passed HIPAA audit within 2 months. Tech stack: Express.js, PostgreSQL, AWS KMS, Terraform.
Multi-tenant SaaS backend for B2B analytics
Designed isolated tenant databases and a shared billing engine. Scaled from 50 to 500 tenants in 6 months without downtime. Tech stack: Node.js, MongoDB Atlas, Stripe, AWS ECS.
Order management system for an ecommerce brand
Replaced a legacy PHP system with a Node.js microservices architecture. Cut order processing time from 15 minutes to 30 seconds. Tech stack: Express.js, PostgreSQL, Redis, Docker.
FERPA-compliant LMS backend for EdTech
Built student data APIs with role-based access control. Handled 10,000 concurrent users during peak exam periods. Tech stack: Node.js, MySQL, Okta, AWS CloudFront.
Inventory sync engine for a logistics platform
Created a Kafka-based pipeline that syncs inventory across 20 warehouses in real time. Reduced stock discrepancies by 95%. Tech stack: Node.js, Kafka, PostgreSQL, AWS MSK.
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. You know the exact cost before we write a line of code.
Senior engineers only
IRPR employs no juniors. Every engineer has 8+ years of backend experience and has shipped at least 5 production systems. Your codebase is in experienced hands.
Compliance baked in from day one
We build with HIPAA, SOC 2, PCI-DSS, and FERPA controls from the first sprint. No retrofitting - your backend passes audits faster and costs less to maintain.
Full code ownership
You own all source code, documentation, and infrastructure scripts. No licensing fees, no vendor lock-in. Your team can take over immediately after launch.
2-week sprints with visible progress
You see a working demo every two weeks. We adjust priorities based on your feedback. No black box development where you wait months to see anything.
30-day free post-launch support
After release we provide 30 days of free support including bug fixes, monitoring adjustments, and knowledge transfer sessions. Your team gets ramped up fast.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
