Professional Backend App Development AgencyBackend App
We build backend systems that scale. 200+ products shipped with Node.js, Go, Python, and cloud-native architectures.
IRPR builds backend systems for apps that handle real user traffic, data processing, and third-party integrations. We use Node.js, Go, Rust, Python, and deploy on AWS, GCP, or Azure with containers and serverless.
We ship production-ready backend code in 12-14 weeks for MVPs, with fixed pricing from $80,000 to $250,000. Every project meets SOC 2 or HIPAA compliance if needed.
Our clients are CTOs scaling an API product, founders needing a backend for their mobile app, and engineering leads migrating monolithic legacy systems to microservices.
Types of software we ship.
REST API Development
Build REST APIs for web and mobile apps. Integrates with Stripe, Twilio, and Auth0. Supports OAuth 2.0 and JWT.
Microservices Architecture
Decompose monoliths into independent services. Uses Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
Real-Time Data Processing
Handle live data streams with WebSockets, Apache Kafka, and Redis. Used for chat, notifications, and live dashboards.
Serverless Backend
Reduce costs and operational overhead with AWS Lambda, Cloud Functions, and DynamoDB. Scales automatically.
GraphQL API Development
Flexible query interfaces using Apollo, GraphQL, and Prisma. Reduces over-fetching and speeds up frontend development.
Database Design and Optimization
Design schemas for PostgreSQL, MongoDB, and Cassandra. Tune queries, add indexes, and implement replication.
Authentication and Authorization Systems
Implement OAuth 2.0, SAML, or custom JWT flows. Integrates with Okta, Auth0, and Azure AD.
Cloud Infrastructure and DevOps
Set up CI/CD pipelines with GitHub Actions, Terraform, and Jenkins. Deploy to AWS, GCP, or Azure with monitoring via Datadog.
We build for every business type.
SaaS platforms
Healthcare apps
Fintech systems

Measurable results from professional backend development
Every backend system we build delivers real metrics that matter to your business.
IRPR has shipped 200+ backend products across 50 countries. Our systems handle millions of requests per day with 99.9% uptime. We use tools like New Relic and Datadog to monitor performance from day one.
For a fintech client, we reduced API response time from 450ms to 90ms by rewriting the data layer in Go and adding Redis caching. The result was a 35% increase in user retention.
Generic dev shop vs professional backend agency
Not all development teams deliver the same quality. Here is how IRPR differs from a generic shop.
Many agencies charge hourly and let scope creep inflate costs. They assign junior developers and skip documentation. That leads to brittle code and missed deadlines.
IRPR works with a fixed price, senior engineers only, and a clear Roadmap phase. We write unit tests, API docs, and deploy with CI/CD from sprint one.
- Hourly billing with no price cap
- Junior developers on critical code
- No written architecture plan
- No API documentation
- Manual deployment process
- No monitoring or alerting setup
- Fixed price, no surprise invoices
- Senior engineers only (8+ years experience)
- Architecture document in Roadmap phase
- Auto-generated API docs with OpenAPI
- CI/CD pipeline from day one
- Sentry + Datadog monitoring included
Our backend development process
We follow a four-phase process that turns your idea into a working backend system.
Every engagement starts with a 2-week Discovery phase where we map your data, users, and integrations. Then we move to Roadmap, where we produce a fixed-price quote and a detailed timeline.
After approval, we begin 2-week Sprint cycles. Each sprint delivers a shippable increment. The final Release phase includes load testing, documentation, and handover.
What ships with every backend project
Our delivery includes everything you need to run and maintain the system.
We treat your project as production-ready from the first sprint. That means code, infrastructure, and documentation are all part of the package.
You get full ownership of the source code, deployment scripts, and monitoring dashboards. No black boxes.
- Source code in your GitHub or GitLab repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Infrastructure as code with Terraform or Pulumi
- API documentation with OpenAPI/Swagger
- Sentry error tracking and New Relic monitoring
- Postman collection for testing
- Load test report with k6 or Locust
- Architecture diagram and runbook
What we ship in this practice.
Real-time bidding platform
Built a WebSocket-backed bidding engine for an ad exchange. Processed 50,000 bids per second with sub-100ms latency. Tech stack: Go, Redis, Kafka, AWS ECS.
Telemedicine backend
Developed a HIPAA-compliant patient portal backend. Handles video scheduling, secure messaging, and EHR integration. Reduced appointment no-shows by 40%. Tech stack: Node.js, PostgreSQL, Twilio, AWS.
Payment processing system
Built a PCI-DSS compliant payment gateway for a fintech startup. Processes 10,000 transactions per minute with automatic fraud detection. Tech stack: Python, Django, Stripe, Redis, Kubernetes.
Multi-vendor ecommerce backend
Created an order orchestration system for a marketplace with 500+ vendors. Automated inventory sync and shipping label generation. Reduced manual data entry by 8 hours per week. Tech stack: Ruby on Rails, PostgreSQL, Shopify API, Sidekiq.
SaaS analytics microservices
Refactored a monolith into 12 microservices for a B2B analytics company. Improved deployment frequency from monthly to weekly. Tech stack: Node.js, Express, MongoDB, RabbitMQ, Docker.
Real estate property search API
Built a GraphQL API aggregating MLS data from 5 sources. Reduced query time from 8 seconds to 400ms with caching and batch loading. Tech stack: Apollo Server, GraphQL, Redis, PostGIS.
Why teams hire us.
Fixed price, not hourly billing
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 total cost before we write a single line of code.
Senior engineers only
Our team averages 10 years of backend experience. Every engineer has shipped production systems at scale. We do not assign juniors to critical infrastructure.
Production-ready from sprint one
We deploy to staging in the first sprint and to production by week 8. Every build includes tests, logging, and monitoring. No throwaway prototypes.
Compliance expertise built in
We have delivered HIPAA, PCI-DSS, and SOC 2 compliant backends for 40+ clients. We build audit trails, encryption, and access controls from day one.
Full code ownership
You own everything we build. Source code, infrastructure scripts, documentation - all in your repository. No licensing fees, no vendor lock-in.
Clear timeline and transparency
We ship in 8-12 weeks for MVPs. You get a detailed timeline in the Roadmap. We share a live dashboard showing sprint progress and blockers.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
