Best Backend App Development AgencyBackend App
You need a backend that scales. IRPR builds production-ready APIs and microservices for apps used by millions.
IRPR builds production backends using Node.js, Python, Go, and PostgreSQL with Redis caching and Docker containers. Every architecture is designed for horizontal scaling and 99.9% uptime.
A typical MVP ships in 8-12 weeks with a fixed price between $80K and $250K. All backends meet SOC 2, HIPAA, or PCI-DSS compliance requirements depending on your industry.
SaaS founders hire us to build scalable APIs that handle millions of requests. Fintech CTOs need PCI-DSS compliant payment backends. Healthcare companies require HIPAA-compliant data pipelines. Ecommerce brands trust us for high-throughput order processing.
Types of software we ship.
REST API
Stateless REST APIs built with Express.js or FastAPI. Integrated with Stripe, Twilio, and Auth0 for payments, messaging, and auth.
GraphQL API
GraphQL endpoints using Apollo Server and Prisma ORM. Reduces over-fetching and accelerates frontend development for complex apps.
Microservices
Decoupled microservices with message queues (RabbitMQ, Kafka) and service mesh (Istio). Each service scales independently on Kubernetes.
Real-time Backend
WebSocket and SSE backends using Socket.IO and Redis Pub/Sub. Supports live chat, notifications, and real-time data streams.
Event-driven Backend
Event-driven architectures with AWS Lambda, SQS, and DynamoDB Streams. Ideal for data processing pipelines and asynchronous workflows.
Backend for Mobile
Optimized for mobile clients with Firebase Cloud Functions, Google Cloud Tasks, and offline sync via PouchDB. Handles 100K+ concurrent users.
Backend for Web Apps
Full-stack backends integrated with Next.js, Vue, or React. Includes session management, rate limiting, and database migrations.
Backend for IoT
IoT backends using MQTT brokers (Mosquitto), InfluxDB time-series, and AWS IoT Core. Processes millions of device telemetry events per minute.
We build for every business type.

Why IRPR is the best backend app development agency
We ship faster and with less risk than any other agency because we combine senior engineers with a repeatable product process.
Every backend project starts with a 1-week architecture review. Our CTO maps out caching strategies, database sharding, and deployment topology before writing a line of code.
We have built 200+ backends for companies in 50 countries. On average, we deliver the MVP in 12 weeks with 98% on-time record and 99.9% production uptime.
The difference between IRPR and generic backend agencies
Most agencies bill hourly and disappear after launch. IRPR gives you fixed pricing, full transparency, and a 99.9% uptime SLA.
Generic shops often use juniors and change requirements mid-project. We put a senior architect on every engagement and freeze the scope after the Roadmap phase.
With IRPR you get a fixed price contract, weekly demos, and the same engineering team from architecture to release. No surprises.
- Hourly billing with no cap
- No architecture review up front
- Forces you into one stack
- No compliance expertise
- No post-launch uptime guarantee
- Code ownership often unclear
- Fixed price from week 2
- Architecture review in week 1
- Stack agnostic (Node, Go, Python, .NET)
- SOC 2, HIPAA, PCI-DSS built in
- 99.9% uptime SLA included
- You own 100% of the code
Our backend development process
We follow a repeatable 4-phase process that turns your idea into a production system in 12 weeks.
Each phase has clear deliverables and a gate review. You see working code every two weeks, not just slide decks.
We use the same processes that ship 200+ products - automated testing, infrastructure as code, and zero-downtime deployments.
What ships with your backend
You get a fully productionized system, not just code files. Every deliverable is documented and automated.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and auto-deploy
- Docker containers for every service
- Infrastructure as code (Terraform or Pulumi)
- API documentation (Swagger/OpenAPI or Postman collection)
- Monitoring dashboards (Datadog, CloudWatch, Sentry)
- Load testing results with k6 or Artillery
- Deployment runbooks and rollback procedures
What we ship in this practice.

Why teams hire us.
Fixed price from week 2
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
All backend engineers have 10+ years of experience. We do not hire juniors or outsource to contractors. Every line of code is reviewed by a principal engineer.
Compliance built in
SOC 2 Type II, HIPAA, and PCI-DSS compliance are part of our standard build process. We sign BAAs and undergo quarterly audits for regulated industries.
10-week average MVP timeline
From idea to production in 8-12 weeks. Our fastest backend MVP shipped in 6 weeks for a YC startup. We focus on getting you to market fast.
Full code ownership
You own everything we build - no licensing fees, no platform lock-in. All code, infrastructure scripts, and documentation are transferred to your repos.
99.9% uptime SLA
All production backends come with a guaranteed 99.9% uptime SLA. We monitor with Datadog and provide 24/7 on-call support for the first 6 months.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
