Senior backend app development company with a track record
We deliver reliable backend systems that scale.
IRPR has shipped 200+ backend projects for clients in 50+ countries. Our engineers average 12 years of experience.
We maintain 99.9% uptime on production systems and 98% of projects launch on time.
Hiring a senior backend app development company vs a generic dev shop
Not all development teams are equal. The difference shows in code quality and delivery speed.
Generic shops often assign junior developers to your project and charge hourly. They deliver incomplete code with no documentation.
IRPR assigns senior engineers only, uses fixed pricing, and ships full production code including tests and CI/CD.
- Junior developers on your project
- Hourly billing with no cap
- No CI/CD pipeline
- No monitoring or alerting
- Code ownership unclear
- Scope creep leads to delays
- Senior engineers with 10+ years
- Fixed price from the Roadmap phase
- CI/CD on GitHub Actions
- Sentry error tracking and PagerDuty alerts
- Full code ownership transferred
- Agile sprints with transparency
Our 4-phase process for senior backend app development
We move from idea to production in 8-12 weeks.
Phase 1: Idea Validation and Architecture Design. We review your requirements and design the system architecture, including database schema, API endpoints, and infrastructure.
Phase 2: Roadmap and Fixed Quote. We create a detailed roadmap with milestones and lock the price. No surprises.
What ships with every backend project
Every deliverable is production-ready and fully documented.
All code is in your repository with full documentation and automated testing. You get everything you need to run and maintain the system.
- Source code in your GitHub or GitLab repo
- PostgreSQL database schema with migrations
- RESTful API endpoints with OpenAPI spec
- Docker containers for local development
- CI/CD pipeline via GitHub Actions
- Sentry error tracking integration
- PagerDuty alerting for production
- Unit and integration tests (80%+ coverage)
- API documentation (Swagger/Postman collection)
- Deployment runbook with SSH and secrets management
What we ship in this practice.
Real-time analytics dashboard for a SaaS platform
Built a streaming backend using Kafka, Flink, and PostgreSQL that processes 10 million events per day. The client reduced data latency from hours to seconds and cut infrastructure costs by 40%.
Payment processing API for a fintech startup
Developed a PCI-DSS compliant payment gateway with Go, Stripe Connect, and Redis. The system handles 5,000 transactions per minute with 99.9% uptime.
HIPAA-compliant patient data API for a healthcare app
Built FHIR-based APIs with Node.js and PostgreSQL on AWS. The system manages 200,000 patient records with full audit logging and BAA compliance.
Multi-vendor marketplace backend for an ecommerce platform
Designed a microservices architecture with NestJS, RabbitMQ, and MySQL. Supports 1,000 vendors, real-time inventory sync, and automated commission settlements.
Content distribution API for a media company
Created a serverless backend using AWS Lambda, API Gateway, and DynamoDB that delivers personalized content feeds to 5 million users with sub-100ms latency.
User notification system for a social networking app
Implemented a real-time notification service with WebSockets, Redis Pub/Sub, and Firebase Cloud Messaging. Handles 1 million notifications per day with delivery guarantee.
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.
Senior-only engineers
All engineers have 10+ years of experience. We never outsource or staff juniors. Your backend is built by a principal-level developer.
Full code ownership
You own 100% of the source code from day one. IRPR does not claim any intellectual property. The code is in your repository.
12-week MVP guarantee
We ship production-ready MVPs in 8-12 weeks. Our roadmap phase ensures we meet tight deadlines without sacrificing quality.
Compliance-ready systems
We build to HIPAA, PCI-DSS, and SOC 2 standards. Your backend is audit-ready from launch, with encryption, logging, and access controls.
30-day warranty and ongoing support
We provide 30 days of warranty support after launch. Extended maintenance contracts are available at $5,000 per month for uptime and minor updates.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
