Top Backend App Development ConsultantsBackend App
We build production-ready backend systems in 8-12 weeks. Ships with full ownership, CI/CD, and monitoring.
IRPR is a team of senior backend engineers who build custom backend apps for SaaS companies, fintechs, and enterprises. We use Node.js, Python, Go, PostgreSQL, Redis, and Docker to ship reliable server-side systems that handle high traffic and complex data.
Every project delivers in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2, so your backend passes audits out of the gate.
Our clients include CTOs scaling their SaaS platform from 10k to 1M users, founders building a backend MVP in 10 weeks, enterprise teams modernizing legacy monoliths, and product managers who need a dedicated backend team without hiring overhead.
Types of software we ship.
REST API Development
Builds resource-oriented APIs with documentation and versioning using Express or Fastify, deployed on AWS API Gateway.
Microservices Architecture
Splits monolithic backends into independent services with RabbitMQ or Kafka for async communication.
Event-Driven Systems
Designs systems that react to events via AWS EventBridge or Redis Streams, decoupling producers and consumers.
GraphQL API Design
Creates a single query layer using Apollo Server or Yoga, reducing over-fetching for React and mobile clients.
Serverless Backend
Uses AWS Lambda or Cloud Functions with DynamoDB to scale automatically and reduce cost for variable workloads.
Backend for Mobile Apps
Builds Push Notifications with Firebase, user auth via Auth0, and realtime sync with Firestore or Supabase.
Real-Time Chat Backend
Implements WebSocket servers with Socket.IO or AWS WebSockets, handling presence, typing indicators, and message persistence in Redis.
File Processing Pipelines
Processes images and documents at scale with S3 triggers, FFmpeg, and Step Functions for video transcoding pipelines.
We build for every business type.
SaaS companies
Fintech and finance
Healthcare
Ecommerce
Logistics and travel
Why hire top backend app development consultants
We deliver production backend systems that run at scale without constant firefighting.
IRPR has shipped over 200 backend systems, from SaaS backends handling 1M+ daily requests to HIPAA-compliant patient data platforms. Our average timeline is 12 weeks from kickoff to deploy, and we hit 98% on-time delivery across all projects.
We use Node.js, Python, Go, and Rust depending on your performance needs. Every system includes CI/CD, monitoring with Datadog or Sentry, and a deployment on AWS or GCP. You own the code and the infrastructure starting day one.
How we differ from other backend consultants
Most agencies overpromise and underdeliver. We are built differently.
Generic dev shops often use junior engineers, charge by the hour, and hand over code with no docs or DevOps. You end up with a fragile backend that breaks on the first traffic spike.
IRPR assigns senior engineers only - average 8 years experience. We give you a fixed price in week two, not an hourly bill. Every backend ships with a CI/CD pipeline, automated tests, and a runbook.
- Junior engineers learning on your project
- Hourly billing with no cap
- No automated tests shipped
- Manual deployment, no CI/CD
- No monitoring or alerting
- Code ownership unclear
- Senior engineers only (8+ years avg)
- Fixed price from Roadmap phase
- 100% automated test coverage
- CI/CD pipeline on GitHub Actions
- Sentry error tracking + Datadog dashboards
- You own everything - source code, infra, docs
Our process for backend app development
From idea to production in four phases, 8-12 weeks total.
We start with a 1-week Idea phase where we define scope, tech stack, and milestone plan. Then a 1-week Roadmap delivers a fixed-price proposal with a detailed backlog.
The Product phase runs 6-10 weeks of sprints, shipping working backend increments every two weeks. Release includes deploy, monitoring, and a knowledge transfer session.
What ships with your backend system
Every project includes these deliverables by default.
We do not just write code. We hand over a production-ready backend that your team can operate immediately. All assets are in your cloud account from day one.
Our default delivery includes a fully documented codebase, automated tests, a CI/CD pipeline, and monitoring dashboards. You never have to ask for these - they are part of the price.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with tests and deploy
- PostgreSQL schema and migration scripts
- API documentation (OpenAPI/Swagger)
- Sentry error tracking and performance monitoring
- Datadog dashboards for system health and latency
- Infrastructure as Code using Terraform or Pulumi
- Runbook with incident response steps
- Admin dashboard or CLI for managing users and data
- One year of bugfix support included in the contract
What we ship in this practice.
SaaS subscription billing backend
Built a multi-tenant billing system with Stripe integration, metered usage, and proration. Reduced billing errors by 40% and cut invoice generation time from 2 hours to 5 minutes. Tech stack: Node.js, PostgreSQL, Stripe API.
Real-time fraud detection engine
Designed an event-driven pipeline using Kafka and ML models to flag suspicious transactions in under 50ms. Decreased false positives by 60%. Tech stack: Python, Kafka, Redis, AWS Lambda.
HIPAA-compliant patient data API
Built a FHIR-compliant API for a telehealth startup, handling patient records, appointments, and video session data. Passed HIPAA audit on first attempt. Tech stack: Go, PostgreSQL, Auth0, AWS KMS.
Ecommerce inventory and order backend
Created a real-time inventory management system syncing with Shopify and warehouse APIs. Reduced stockout events by 70% during Black Friday. Tech stack: Ruby on Rails, PostgreSQL, Redis, Sidekiq.
Logistics route optimization API
Developed a GraphQL API that computes optimal delivery routes using Google Maps and custom heuristics. Cut average delivery time by 25% for a 100-driver fleet. Tech stack: Node.js, PostgreSQL, Google Maps API.
Real-time chat backend for a social app
Built a WebSocket server supporting 50K concurrent connections with message persistence and typing indicators. Handled 1M messages per day with <100ms latency. Tech stack: Node.js, Socket.IO, Redis, MongoDB.
Why teams hire us.
Fixed price, not hourly billing
Every backend project gets a fixed quote after the Roadmap phase (week 2). No hourly meters, no surprise invoices. Budget is locked from the start.
Senior engineers only
Our team averages 8+ years of backend development experience. No junior engineers. Every developer has shipped production systems with 99.9% uptime.
Compliance built in from day one
We build HIPAA, PCI-DSS, and SOC 2 compliant backends using encrypted databases, audit logs, and secure APIs. You skip the rework cycle.
Full code and infrastructure ownership
You get the source code, CI/CD scripts, Terraform configurations, and all credentials. Nothing stays locked behind IRPR. You can take it anywhere.
12-week average timeline to production
We ship a working backend in 8-12 weeks minimum. Our process is optimized for speed without cutting corners on testing or documentation.
No scope creep - we enforce scope boundaries
Every change request goes through a formal impact assessment. If it adds value, we adjust the fixed price transparently. No hidden renegotiations.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
