Expert Backend App Development VendorBackend App
We build scalable backend systems in 8-12 weeks. Fixed price, senior engineers, no surprises.
IRPR is an expert backend app development vendor that builds production-grade systems using Node.js, Python, Go, and cloud infrastructure on AWS, GCP, or Azure. We design database architectures with PostgreSQL or MongoDB and deploy containerized microservices on Kubernetes.
Every project ships in 8-12 weeks with a fixed price ranging from $80K to $250K depending on complexity. Our backends meet HIPAA, PCI-DSS, and SOC 2 compliance out of the box, with automated CI/CD pipelines and 99.9% uptime SLAs.
Founders with a validated idea hire us to build the backend infrastructure they can't build in-house. CTOs at funded startups bring us in to replace a slow or unreliable prototype. Enterprise product managers work with us to add a new API layer without disrupting existing systems.
Types of software we ship.
RESTful API backend
Stateless REST APIs with JWT auth, rate limiting, and Swagger documentation. Built with Node.js or Go on AWS Lambda or EC2.
GraphQL API backend
Schema-driven GraphQL backends using Apollo Server or Hasura. Real-time subscriptions, data loaders, and federation for distributed teams.
Microservices architecture
Decoupled microservices on Kubernetes with gRPC or RabbitMQ messaging. Each service scales independently and has its own database.
Event-driven data pipeline
Stream processing backends using Apache Kafka or AWS Kinesis. Handle millions of events per day for analytics, logging, or monitoring.
Serverless backend
Zero-infrastructure backends on AWS Lambda or Cloudflare Workers. Pay per request, auto-scale, and no servers to manage.
Database-optimized backend
Backends built around a single database—PostgreSQL for transactional data, MongoDB for flexible schemas, or TimescaleDB for time-series.
Backend for AI/ML inference
High-throughput backends serving trained models via TensorFlow Serving or PyTorch. Batch inference, caching, and GPU provisioning.
Multi-tenant SaaS backend
Isolated tenant data in shared databases with row-level security. Tenant-aware routing, quota enforcement, and usage metering.
We build for every business type.

What makes an expert backend app development vendor
IRPR delivers backend systems that stay reliable at scale.
An expert backend app development vendor doesn't just write code. They design for traffic spikes, data integrity, and team handoff. IRPR uses PostgreSQL with connection pooling, Redis for caching, and NGINX reverse proxies to handle 10,000 concurrent users from week one.
Every backend ships with automated load testing results, database migration scripts, and a Grafana dashboard. You get a system that survives Black Friday traffic without a single page of emergency code.
Generic dev shops vs an expert backend app development vendor
Not every development firm can build a real backend.
A generic shop often delivers a monolithic codebase on a single server. They use shared hosting, skip database indexing, and write APIs without rate limiting. The result breaks at 500 users.
IRPR builds every backend as a set of containerized services on Kubernetes or ECS. We add load balancers, read replicas, and automated failover. Your system stays up when traffic spikes 10x.
- Monolithic code with no separation of concerns
- Single MySQL database with no replication
- No load testing before launch
- APIs without authentication or rate limiting
- Manual deployment via FTP or SSH
- No monitoring or alerting
- Microservices or modular monolith based on scale needs
- PostgreSQL with read replicas and automated backups
- Load testing with k6 targeting 10,000 concurrent users
- JWT auth, role-based access, and rate limiting per endpoint
- CI/CD pipeline with GitHub Actions and Terraform
- Grafana dashboards and PagerDuty alerts from day one
How IRPR works as your expert backend app development vendor
Our process turns your idea into a production-ready backend in 8-12 weeks.
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase ends with a sign-off and fixed budget. No scope creep, no extra charges.
The Roadmap phase (week 2) produces a detailed technical specification with database schema, API endpoints, and infrastructure diagram. You approve it before we write any code.
What ships when you hire an expert backend app development vendor
You own everything. No black boxes, no proprietary lock-in.
Every engagement ends with full source code ownership and a deployed, running system. We transfer all GitHub repositories, CI/CD configurations, and cloud infrastructure templates to your team.
You also get a one-week knowledge transfer session where we walk your engineers through the codebase, the deployment pipeline, and the monitoring setup.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions or GitLab CI
- PostgreSQL database with migration scripts
- RESTful API with Swagger documentation
- Authentication system with JWT and role-based access
- Dockerized services with docker-compose and Dockerfile
- Terraform configuration for AWS or GCP infrastructure
- Load testing reports from k6
- Grafana dashboard with uptime, latency, and error rates
- One-week knowledge transfer session for your team
What we ship in this practice.
Multi-tenant SaaS backend for a B2B startup
IRPR built a multi-tenant backend with row-level security in PostgreSQL for a B2B SaaS startup. The system handles 2,000 tenants on a single database cluster using Amazon RDS. Tech stack: Node.js, Express, PostgreSQL, Redis, AWS ECS.
HIPAA-compliant API for a telehealth app
We built a HIPAA-compliant API layer for a telehealth platform. The backend supports 500 concurrent video sessions with encrypted data storage and audit logging. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS, Twilio.
Real-time order processing backend for an ecommerce brand
An ecommerce brand needed a backend that processes 10,000 orders per day with real-time inventory sync. IRPR built an event-driven system using Kafka and a RESTful API. Tech stack: Go, Kafka, Redis, PostgreSQL, AWS Lambda.
PCI-DSS compliant payment backend for a fintech startup
IRPR built a PCI-DSS Level 1 compliant backend for a payment processing startup. The system tokenizes card data and routes transactions through Stripe Connect. Tech stack: Ruby on Rails, PostgreSQL, Stripe API, AWS Nitro Enclaves.
Scalable matching engine for a logistics marketplace
We built a real-time matching backend for a logistics marketplace that connects shippers with carriers. The system processes 5,000 match requests per minute with geospatial queries. Tech stack: Node.js, MongoDB, Redis, AWS EKS, WebSocket.
Content delivery backend for a media streaming platform
IRPR built a media streaming backend that supports 10,000 concurrent viewers with adaptive bitrate streaming. The system uses CDN caching and pre-signed URLs. Tech stack: Python, Django, PostgreSQL, AWS CloudFront, FFmpeg.
Why teams hire us.
Senior engineers only, no juniors
Every engineer at IRPR has 8+ years of experience building production backends. We don't use junior or mid-level developers on client projects. You get a staff engineer from day one.
Fixed price from the roadmap
We quote a fixed price during the Roadmap phase (week 2). That number does not change. No hourly billing, no surprise invoices, no scope creep.
8-12 week delivery, on time 98%
Our average project ships in 8-12 weeks. 98% of our projects hit the original delivery date. We ship working software every 2 weeks in sprints.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from sprint one. You don't need a separate audit remediation phase. We handle encryption, auditing, and access controls upfront.
You own the code and infrastructure
Every project delivers full source code ownership. We transfer all GitHub repos, CI/CD pipelines, and Terraform templates to your account. No proprietary frameworks, no lock-in.
Production support after launch
We provide 30 days of production support after launch, including bug fixes and monitoring tuning. You get a direct Slack channel with the engineering team. 99.9% uptime SLA included.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
