Professional Backend App Development ServicesBackend App Development
We build server side systems that handle millions of requests. 200+ products shipped, 12-week delivery, fixed price.
IRPR provides professional backend app development services for startups and enterprises. We build server-side systems using Node.js, Python, Go, PostgreSQL, Redis, and AWS or GCP cloud infrastructure. Every project gets CI/CD pipelines, automated testing, and monitoring from day one.
Your project ships in 12 weeks with a fixed price ranging from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Source code is fully owned by you. No license fees, no royalties.
We work with CTOs who need a scalable backend without hiring a full team. Startup founders launching a SaaS product. Enterprise engineering leads migrating legacy systems to the cloud. And product managers who need a reliable API layer for their mobile or web app.

Why professional backend app development matters
A backend that is slow or unreliable will kill your product before it gains traction.
IRPR has shipped over 200 backend systems across 50 countries. Our average backend handles 10,000 requests per second at peak with 99.9% uptime. We use PostgreSQL for data storage, Redis for caching, and AWS for hosting. Every API endpoint is tested with 95% code coverage target.
Our fixed price model means no surprise invoices. A typical backend project costs $80K to $250K and takes 12 weeks. We include CI/CD pipeline on GitHub Actions, Sentry error tracking, and Datadog monitoring. Your team gets full source code and documentation.
The difference between generic dev shops and IRPR
Most development agencies bill hourly and let the scope grow. IRPR works differently.
Generic dev shops often use junior developers who need weeks to learn your codebase. They bill hourly and have no incentive to finish quickly. Many shops use outdated stacks like PHP or ASP.NET without telling you. Code quality is inconsistent, and you rarely get automated tests or CI/CD.
IRPR assigns a team of 2-3 senior engineers who have built production systems before. Every project starts with a 2 week Roadmap phase where we define the exact scope, tech stack, and fixed price. No hourly billing. No scope creep. You get a cloud native, containerized backend with automated testing and deployment from day one.
- Junior developers learning on your project
- Hourly billing that encourages slow work
- Vague scope that changes every week
- No CI/CD, manual deployments
- No monitoring or error tracking
- Code dumps without documentation
- Senior engineers with production experience
- Fixed price per project, no surprises
- 2 week Roadmap defines scope exactly
- CI/CD pipeline from day one
- Sentry and Datadog monitoring
- Full documentation and source code ownership
How we build your backend in 12 weeks
Our process is structured so you know exactly what ships each week.
Every IRPR backend project follows a 4 phase framework: Idea, Roadmap, Product, Release. The Roadmap phase takes 2 weeks and produces a detailed scope document with wireframes, data models, and API contracts. After you approve the Roadmap, the price is locked and we start building.
The Product phase runs for 8 weeks. We work in 2 week sprints with demos at the end of each sprint. You see real working code every 2 weeks. The final 2 weeks are for Release: load testing, security audit, deployment, and documentation. Your backend ships on time with zero technical debt.
Everything that ships with your backend
You get more than just code. Every project includes these deliverables.
Our professional backend app development services are designed to give you a complete, production-ready system. You don't just get an API — you get monitoring, logging, CI/CD, and full documentation. Your team can take over maintenance immediately.
Every project is built with Docker containers deployed on AWS or GCP. We use Terraform for infrastructure as code, so you can recreate the entire environment with one command. Security scanning is built into the pipeline. We never ship vulnerable dependencies.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containers for each service
- PostgreSQL database with migrations
- Redis cache layer for fast responses
- Sentry error tracking and alerts
- Datadog monitoring dashboard
- Swagger/OpenAPI documentation
- Load test report with results
- Deployment runbook and handover guide
What we ship in this practice.
Subscription billing backend for a SaaS platform
We built a recurring billing system with Stripe integration, webhook handling, and proration logic. The backend handles 50,000 subscribers with 99.9% uptime. Tech stack: Node.js, PostgreSQL, Redis, Stripe API.
Real time inventory API for an ecommerce marketplace
We developed a WebSocket based inventory system that updates stock levels across 200+ vendors in real time. Order processing time dropped from 5 seconds to 200 milliseconds. Tech stack: Go, PostgreSQL, RabbitMQ, AWS ECS.
HIPAA compliant patient portal backend
We built a secure backend for a telemedicine startup handling PHI. Includes audit logging, role based access, and encrypted storage. Passed HIPAA audit with zero findings. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS.
Payment processing API for a fintech app
We created a PCI DSS compliant payment gateway with tokenization, fraud scoring, and dispute management. The system processes $5M in transactions monthly. Tech stack: Node.js, PostgreSQL, Redis, Stripe, Plaid.
MLS data integration backend for a real estate platform
We built an API that ingests and normalizes MLS listings from 50+ regional databases. Data syncs every 15 minutes with deduplication and geocoding. Tech stack: Python, PostgreSQL, Elasticsearch, AWS Lambda.
Background job processor for a media analytics tool
We developed an async task queue that processes video uploads, generates thumbnails, and runs sentiment analysis. Processed 10,000 jobs per day with 0 failures. Tech stack: Python, Celery, Redis, AWS S3, Google Vision API.
Why teams hire us.
Fixed price, not hourly
Every IRPR project gets a fixed quote after the Roadmap phase. You know the exact cost before we write a single line of production code. No hourly billing means no incentive to drag out the work.
Senior engineers only
We never staff junior developers. Every engineer on your project has 10+ years of experience building production systems. Our team includes former AWS engineers and PostgreSQL contributors.
12 week delivery guarantee
Average project ships in 12 weeks from Roadmap approval. We use strict 2 week sprints with demos. If we miss the deadline, we discount your next sprint. This has happened less than 2% of the time.
Full code ownership
You own all source code, documentation, and deployment scripts. No licenses, no royalties, no ongoing fees. You can take the code and run it yourself or hire another team.
Built for compliance
We have built over 30 HIPAA compliant systems, 20 PCI DSS certified backends, and 15 SOC 2 audited platforms. Our infrastructure scripts include encryption, audit logging, and access controls by default.
Production ready from day one
Every backend includes automated testing, CI/CD, monitoring, and error tracking. Your system ships with Datadog dashboards, Sentry alerts, and a deployment runbook. No technical debt, no shortcuts.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
