Senior Custom Backend Development StudioBackend Development
We build production-ready backend systems with senior engineers only. Fixed pricing, 8-12 week delivery, and full ownership of your code.
IRPR builds custom backend systems using Node.js, Python, Go, and Rust. We design RESTful APIs, event-driven architectures, and microservices that scale.
Every project ships with a complete backend codebase, CI/CD pipeline, monitoring, and documentation. Timeline is 8-12 weeks for an MVP. Pricing is fixed, typically $80K-$250K depending on complexity. We comply with HIPAA, PCI-DSS, and SOC 2.
Founders building SaaS products need a backend that handles 100K+ users. CTOs at mid-market companies need to modernize legacy systems. Product managers at healthcare startups need HIPAA-compliant APIs. Ecommerce owners need scalable order processing.
Types of software we ship.
Custom API Development
Build RESTful and GraphQL APIs with Express.js, Apollo, or FastAPI. Includes versioning, rate limiting, and OpenAPI documentation.
Microservices Architecture
Decompose monoliths into independent services using Docker, Kubernetes, and message queues like RabbitMQ or Kafka.
Database Design and Optimization
Design schemas for PostgreSQL, MySQL, or MongoDB. Optimize queries, indexing, and replication for high throughput.
Serverless Backend
Build event-driven backends with AWS Lambda, API Gateway, and DynamoDB. Pay only for execution, scale automatically.
Real-time Data Processing
Implement WebSockets, SSE, or MQTT for live dashboards, chat, and IoT data streams using Socket.io or MQTT brokers.
Third-party Integration Layer
Connect to Stripe, Salesforce, HubSpot, Twilio, and 50+ other services via custom adapters and webhook handlers.
Authentication and Authorization System
Implement OAuth 2.0, JWT, SAML, or OpenID Connect with role-based access control and multi-tenancy.
Backend for Mobile Apps
Create optimized REST/GraphQL APIs for iOS and Android, with offline sync, push notifications, and pagination.
We build for every business type.

Why senior engineers matter for backend development
Senior engineers ship faster, write cleaner code, and produce fewer bugs.
A senior engineer brings 10+ years of experience to every decision. They choose the right database, design fault-tolerant systems, and avoid common pitfalls. Junior developers often miss edge cases that cause outages.
IRPR only hires senior engineers. This means your backend is built with production best practices from day one. We skip the learning curve.
Generic freelancer vs IRPR senior team
Not all backend developers are equal. Here is the difference.
Hiring a single freelancer often means you get one person's skills and availability. If they get sick or quit, your project stalls. They rarely have compliance knowledge or DevOps experience.
IRPR gives you a team of senior engineers with overlapping expertise. We handle architecture, security, deployment, and documentation. You get a reliable partner, not a single point of failure.
- No senior oversight
- Hourly billing with no cap
- No compliance knowledge
- No CI/CD or monitoring
- Code not documented
- Single point of failure
- Senior engineers with 10+ years experience
- Fixed price from the start
- HIPAA, PCI-DSS, SOC 2 compliant
- CI/CD, Sentry, and Datadog included
- Full documentation and architecture diagrams
- Redundant systems with load balancing
How we build your backend in 4 phases
Our process from idea to production.
Every project follows a proven 4-phase process. This eliminates guesswork and ensures you know what you get and when.
We start with a 2-week Roadmap phase to define scope, architecture, and price. Then we build in 2-week sprints with continuous delivery.
What ships with every backend project
No surprises. These are included by default.
Every IRPR backend project includes all the tools you need to run and maintain your system. No hidden fees or missing pieces.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error tracking and performance monitoring
- PostgreSQL or MongoDB database with migrations
- API documentation with Swagger/OpenAPI
- Unit and integration tests (80%+ coverage)
- Docker containers for local development
- Deployment scripts for AWS, GCP, or Azure
- Architecture diagrams (draw.io or Lucidchart)
- 1 hour of post-launch support per week for 30 days
What we ship in this practice.
SaaS Analytics Dashboard Backend
Built a real-time analytics backend for a B2B SaaS startup. The system ingests 1M events/day and serves sub-100ms queries. Tech: Node.js, PostgreSQL, Redis, Kafka.
HIPAA-Compliant Telemedicine API
Developed a secure API for a telemedicine platform handling patient data. Reduced onboarding time from 6 months to 10 weeks. Tech: Python, FastAPI, PostgreSQL, AWS.
Payment Gateway Integration for Fintech
Created a custom payment orchestration layer integrating Stripe, Plaid, and ACH. Handles $5M in monthly transactions. Tech: Go, PostgreSQL, RabbitMQ.
Multi-Vendor Ecommerce Backend
Built a scalable backend for a marketplace with 500+ vendors. Supports real-time inventory sync and order routing. Tech: Ruby on Rails, PostgreSQL, Elasticsearch.
Real-Time Collaboration Tool Backend
Engineered a WebSocket-based backend for a collaborative document editor. Supports 10K concurrent users with <50ms latency. Tech: Node.js, Redis, MongoDB, Socket.io.
Enterprise Data Lake Backend
Designed a data pipeline for a logistics company processing 10TB of shipment data daily. Uses event sourcing and stream processing. Tech: Java, Apache Kafka, Cassandra, Spark.
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.
Senior engineers only
We hire senior engineers with 10+ years of experience. No juniors, no offshoring, no knowledge gaps.
Compliance built-in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends from day one. No retrofitting security after the fact.
Full ownership of code
You own every line of code, all IP, and all documentation. No lock-in, no licensing fees.
8-12 week MVPs
Most backends ship in 8-12 weeks. We use proven patterns and senior engineers to avoid delays.
Post-launch support included
Every project includes 30 days of post-launch support with weekly check-ins. We fix issues and answer questions.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
