Best Custom Backend Development StudioBackend Development
We build production-grade backends for SaaS, fintech, and healthcare. 8-12 week delivery with a fixed price.
IRPR is a custom backend development studio that builds production-ready systems using Node.js, Python, Go, PostgreSQL, Redis, Docker, and Kubernetes. We design APIs, microservices, and data pipelines that scale from day one.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box. You get source code, CI/CD, and monitoring as standard deliverables.
Our clients are CTOs scaling a SaaS platform, founders needing an MVP backend in 12 weeks, enterprise teams migrating legacy monoliths to microservices, and product managers integrating third-party APIs like Stripe or Salesforce.
Types of software we ship.
RESTful API Development
Build REST APIs with Express or FastAPI. Includes OpenAPI docs, rate limiting, and JWT auth.
Microservices Architecture
Decompose monoliths into Dockerized microservices with RabbitMQ or Kafka for event-driven communication.
Database Design & Optimization
Design normalized schemas in PostgreSQL or MySQL, add caching with Redis, and optimize slow queries.
Serverless Backend
Build serverless backends on AWS Lambda or Cloud Functions with DynamoDB and API Gateway.
Real-Time Data Processing
Implement WebSocket servers with Socket.IO or Phoenix Channels for live dashboards and notifications.
Authentication & Authorization
Set up OAuth2, SAML, or OpenID Connect with Auth0 or Keycloak. Includes role-based access control.
Payment Processing Backend
Integrate Stripe, Braintree, or Adyen for subscriptions, invoicing, and fraud detection.
Cloud Infrastructure & DevOps
Provision AWS, GCP, or Azure with Terraform, set up CI/CD pipelines in GitHub Actions, and configure Datadog monitoring.

Why IRPR is the best custom backend development studio
We deliver backend systems that run reliably in production from day one.
Our team of senior engineers has shipped over 200 backend products across 50 countries. We use Node.js, Python, Go, and modern databases like PostgreSQL and Redis. Every project includes automated testing, CI/CD, and monitoring with Sentry and Datadog.
We specialize in compliance-heavy industries. Our backends pass HIPAA audits, PCI-DSS scans, and SOC 2 reviews. We built a fintech backend that processed $50M in transactions in its first quarter without a single outage.
How we differ from generic backend shops
Most agencies sell you hours. We sell you a finished backend with a fixed price.
Generic dev shops start coding without a roadmap. They bill hourly, change scope, and deliver late. IRPR does the opposite: we spend week 2 building a detailed roadmap with wireframes and API contracts. You approve the plan and the price before we write a line of code.
Our engineers average 10+ years of experience. We don't outsource to junior devs. Every backend is built by a senior engineer who stays on the project until deployment. We guarantee the timeline and the price in writing.
- Hourly billing with no cap
- Junior or offshore developers
- No compliance expertise
- Scope creep without change orders
- No CI/CD or monitoring setup
- You own nothing until paid in full
- Fixed price from the roadmap phase
- Senior engineers only (10+ years avg)
- HIPAA, PCI-DSS, SOC 2 built in
- Scope locked in week 2, no surprises
- CI/CD, Sentry, Datadog included
- Full code ownership from day one
Our backend development process
We follow a four-phase process that turns your idea into a production-ready backend.
Phase 1 is Discovery: we map your domain, data model, and API endpoints. Phase 2 is Roadmap: we deliver a detailed plan with wireframes, schema design, and a fixed price. Phase 3 is Build: our senior engineers code the backend in 8-12 weeks. Phase 4 is Release: we deploy to your cloud, set up monitoring, and hand over the source code.
During Build, you get weekly demos and a staging environment. We use GitHub for version control, Slack for daily updates, and Notion for documentation. No black boxes, no surprises.
What ships with every backend project
Every deliverable is designed to run in production without your team needing to fix anything.
We don't just hand you code on a USB drive. We ship a complete backend with infrastructure, monitoring, and documentation. You can deploy, scale, and debug without calling us.
Our standard delivery includes source code in your private GitHub repo, a CI/CD pipeline using GitHub Actions, error tracking with Sentry, uptime monitoring with Datadog, and a Postman collection for all APIs.
- Source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions
- Sentry error tracking with alerting
- Datadog dashboards for performance and uptime
- Postman collection with all API endpoints
- Database migration scripts (Flyway or Alembic)
- Docker Compose or Kubernetes manifests
- API documentation (Swagger or Redoc)
- Load testing report (k6 or Locust)
- Security audit report (OWASP ZAP or SonarQube)
What we ship in this practice.
Multi-tenant SaaS backend
Built a subscription management backend for a B2B analytics startup. Handles 500+ tenants with isolated data. Reduced onboarding time from 2 weeks to 1 day. Tech stack: Node.js, PostgreSQL, Stripe, Redis.
HIPAA-compliant patient portal API
Developed a REST API for a telemedicine platform. Passed HIPAA audit on first attempt. Processes 10,000+ patient records daily with end-to-end encryption. Tech stack: Python, FastAPI, PostgreSQL, AWS KMS.
Payment processing engine for fintech
Designed a microservices backend for a lending platform. Handles $50M in monthly transactions with 99.99% uptime. Integrates with Plaid and Stripe. Tech stack: Go, Kafka, PostgreSQL, Docker.
Real-time inventory API for ecommerce
Built a WebSocket-based inventory system for a fashion retailer. Updates stock levels in under 200ms across 3 warehouses. Reduced overselling by 95%. Tech stack: Node.js, Socket.IO, Redis, MongoDB.
Legacy monolith to microservices migration
Refactored a 10-year-old Rails monolith into 12 microservices for a logistics company. Cut deployment time from 4 hours to 15 minutes. Tech stack: Python, RabbitMQ, PostgreSQL, Kubernetes.
Data pipeline for real estate analytics
Created an ETL pipeline that ingests MLS data from 50+ sources into a data warehouse. Generates daily reports for 200+ real estate agents. Reduced data latency from 24 hours to 15 minutes. Tech stack: Python, Airflow, Snowflake, dbt.
Why teams hire us.
Fixed price, not hourly
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 cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of experience. No junior devs, no offshore outsourcing. Every backend is built by a senior engineer who stays on the project until deployment.
Compliance built in
We have built backends that passed HIPAA audits, PCI-DSS scans, and SOC 2 reviews. We include encryption, audit logging, and access controls in every project by default.
Async-first, US overlap
Our team works across 50+ countries but overlaps 4 hours with US time zones (9am-1pm ET). You get daily updates and can reach your engineer during US business hours.
Full code ownership
You own the source code, the infrastructure, and the IP from day one. We never charge licensing fees or lock you into a platform. Your code is in your GitHub repo.
12-week MVP guarantee
We ship a production-ready backend in 8-12 weeks. If we miss the deadline, you pay nothing for the final month. That is our guarantee, written into every contract.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
