Senior Backend App Development AgencyBackend Development
We pair you with senior engineers who ship production backend code in 8-12 weeks. Fixed price. No junior developers.
IRPR is a senior backend app development agency. We build backend systems using Node.js, Golang, PostgreSQL, AWS, and Kubernetes. Every engineer on your project has shipped production code for 5+ years.
We deliver a scalable backend in 8-12 weeks at a fixed price between $80K and $250K. Our backends meet compliance standards such as HIPAA, PCI DSS, and SOC 2. You own the full codebase from day one.
CTOs hire us when they need senior backend talent without hiring permanent staff. Founders use us to build MVPs that scale to millions of users. Enterprise teams bring us in to modernize legacy backend architecture. Startups engage us for compliance-ready backend platforms.
Types of software we ship.
REST API Development
Build stateless, versioned REST APIs with Express.js or Fastify. Includes automated testing and Swagger documentation.
GraphQL API Development
Implement GraphQL endpoints with Apollo Server or Yoga. Enables efficient data fetching for mobile and web clients.
Microservices Architecture
Design and deploy microservices on Docker and Kubernetes. Each service has isolated databases and CI/CD pipelines.
Real-time Backend (WebSockets)
Add real-time features using Socket.io, WebSocket, or AWS AppSync. Supports live chat, notifications, and data streaming.
Serverless Backend
Build serverless endpoints with AWS Lambda, API Gateway, and DynamoDB. Pay only for compute, no server management.
Database Design & Migration
Design normalized schemas in PostgreSQL, MySQL, or MongoDB. We handle zero-downtime migrations and query optimization.

Implement OAuth 2.0, JWT, or SAML-based auth with role-based access control. Integrates with Auth0 or Okta.
Background Job Processing
Set up queues with Bull, Sidekiq, or Celery for async tasks like email sends, image resizing, and report generation.
We build for every business type.
SaaS Platforms
Fintech
Healthcare
Ecommerce & Retail
Logistics & Real Estate
Why a senior backend app development agency matters
Junior developers cost less but cost more in rework, security holes, and slow delivery.
A single junior engineer can introduce security vulnerabilities that cost $80K+ to remediate after launch. IRPR assigns only senior backend developers who have built production systems at scale. Each engineer averages 8 years of experience with Node.js, Golang, or Python.
Our senior engineers write code that passes PCI DSS and HIPAA audits. They design for 99.9% uptime from the start. You skip the expensive learning curve and get a backend that handles 10,000+ requests per second.
IRPR vs. generic development shops
Most dev shops staff your project with whoever is available. IRPR staffs only senior backend engineers who align with your stack.
A generic shop might assign a junior developer to your backend because they need hours. That leads to technical debt, slow feature delivery, and audit failures. IRPR never assigns anyone with less than 5 years of production experience.
Our engineers are vetted through a 4-round technical interview that includes system design, coding, and security review. You work directly with the person who writes your code. No account managers, no project handoffs.
- Staffs junior devs to cut costs
- Hourly billing with no cap
- No compliance expertise
- Async communication with 24hr+ delays
- Code not owned by client
- No post-launch monitoring
- Senior engineers only (5+ years)
- Fixed price from the Roadmap phase
- HIPAA, PCI DSS, SOC 2 built in
- Async-first with same-day responses
- Full code ownership upon payment
- Sentry + PagerDuty monitoring included
How we build your senior backend app
Our delivery process is designed for speed and quality. Every phase has clear outputs.
We start with a 1-week kickoff to align on architecture, compliance requirements, and data model. You get a detailed Roadmap document in week 2 with a fixed price and timeline. No changes are made without your written approval.
During the Build phase (weeks 3-10), senior engineers write production code daily with automated CI/CD. You see a running staging environment by week 4. The Release phase includes security testing, load testing, and deployment to your AWS account.
Every backend project ships with these deliverables
You are not buying time. You are buying a complete, production-ready backend system.
IRPR delivers more than just code. Every project includes infrastructure configuration, automated tests, and documentation. You can hand the system to any senior engineer or run it indefinitely with your own team.
Our standard delivery includes a CI/CD pipeline on GitHub Actions, database migrations with version control, and error tracking with Sentry. The system is designed to be deployed in your own AWS, GCP, or Azure account.
- Full source code in your private Git repository
- CI/CD pipeline on GitHub Actions or GitLab CI
- Docker containers with Docker Compose for local dev
- Automated test suite (unit, integration, e2e)
- Swagger/OpenAPI documentation for all endpoints
- Sentry error tracking and performance monitoring
- PagerDuty alert configuration for critical failures
- Secrets management via AWS Secrets Manager or Vault
- Database migration scripts with rollback support
- Post-launch support for 30 days
What we ship in this practice.
HIPAA-compliant telehealth backend
Built a backend for a telemedicine startup that handles patient intake, video sessions, and billing. Reduced data entry time by 40% using PostgreSQL, Node.js, and Twilio Video. Passed HIPAA audit on first try.
Multi-tenant SaaS billing engine
Developed a subscription billing system for a SaaS company processing $2M monthly. Integrated Stripe, handled prorations, and generated automated invoices. Achieved 99.99% uptime over 12 months.
PCI DSS payment gateway adapter
Created a secure payment processing backend for an ecommerce platform. Used tokenization with AWS KMS and encrypted Redis cache. Handles 5,000 transactions per minute at peak.
Real-time ride-sharing dispatch system
Engineered a WebSocket-based dispatch backend using Golang and Redis. Supports 10,000 concurrent drivers with sub-200ms latency. Reduced ride matching time by 60%.
MLS-integrated real estate API
Built a backend that syncs property data from 12 MLS sources. Uses Node.js, PostgreSQL, and Elasticsearch for instant search. Serves 500+ real estate agents daily.
SOC 2 compliance reporting backend
Delivered a backend for a fintech startup that aggregates audit logs, user access records, and control evidence. Generated SOC 2 Type II reports automatically. Reduced compliance prep time from 4 weeks to 3 days.
Why teams hire us.
Senior engineers from day one
Every engineer on your project has 5-15 years of production backend experience. You never get a junior developer working on your system. Our engineers have built backends for companies like Atlassian, Stripe, and Spotify.
Fixed price, not hourly
After the Roadmap phase (week 2) you receive a fixed price and timeline. No hourly billing, no surprise invoices. You know the cost of your backend before any code is written.
Compliance built into the architecture
Our engineers design for HIPAA, PCI DSS, and SOC 2 from the start. We include audit logging, encryption at rest and in transit, and access controls. You save 40-60 hours of compliance rework.
Async-first global delivery
IRPR works across 15+ time zones. You get daily asynchronous updates via Slack or email. Responses within 4 hours during your business hours. No 9-to-5 overhead.
8-12 week delivery
We ship a production-ready backend in 8-12 weeks. The schedule is fixed after the Roadmap. 98% of our projects deliver on time or early.
30 days post-launch support
After release your project includes 30 days of support: bug fixes, monitoring adjustments, and knowledge transfer. You can extend support monthly at a fixed rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
