Senior Backend Development DevelopersBackend Development
Hire senior backend development developers who ship production-grade APIs in 8-12 weeks. Get a fixed price, full code ownership, and compliance built-in.
IRPR builds backend systems for companies that need senior backend development developers. We use Node.js, Go, PostgreSQL, Redis, Docker, and AWS or Azure to deliver production-ready APIs, microservices, and data pipelines.
Every project ships in 8 to 12 weeks with a fixed price between $80K and $250K. We handle compliance (HIPAA, PCI-DSS, SOC 2) from day one, so you don't re-architect later.
We work with CTOs who need to scale infrastructure, VPs of Engineering who want predictable delivery, Technical Product Managers launching new features, and startup founders building their first production system.
Types of software we ship.
RESTful API Development
Build scalable REST APIs with Express.js or FastAPI. Integrate with Stripe, Twilio, and Salesforce.
Microservices Architecture
Decompose monoliths into microservices using Docker, Kubernetes, and gRPC. Reduce deployment time by 60%.
Database Design and Optimization
Design relational (PostgreSQL) and NoSQL (MongoDB, DynamoDB) schemas. Optimize queries to handle 50K+ reads per second.
Cloud Infrastructure (AWS/Azure)
Provision auto-scaling clusters with Terraform. Set up VPCs, load balancers, and RDS for 99.99% uptime.
Real-Time Data Processing
Implement WebSocket servers and Kafka pipelines. Process 10K events per second with <100ms latency.
Authentication & Authorization Systems
Build OAuth2, SAML, or JWT-based auth. Support role-based access control and SSO via Auth0.
Payment Gateway Integration
Integrate Stripe, Braintree, or Adyen. Handle recurring billing, escrow, and multi-currency with PCI compliance.
CI/CD Pipeline Setup
Automate builds with GitHub Actions or CircleCI. Deploy to staging and production with zero-downtime rollouts.
We build for every business type.

Why senior backend development developers matter
Senior backend developers build the systems that keep your product running at scale.
A junior team might ship fast but leave you with technical debt that slows down every future release. Senior backend development developers at IRPR have 10+ years of experience with distributed systems, cloud infrastructure, and production debugging.
We've shipped 200+ products for companies from New York to Singapore. Our developers have built systems that handle millions of API calls per day and process terabytes of data without breaking a sweat.
The difference between generic developers and senior backend development developers
Not all backend shops deliver the same quality. Here's how IRPR compares.
Many agencies hire junior or mid-level developers and charge hourly, creating incentives to work slowly. They skip compliance, use cookie-cutter templates, and rarely test for edge cases.
IRPR assigns only senior backend development developers with a minimum of 10 years of experience. We work on a fixed price, deliver in 8-12 weeks, and include compliance (HIPAA, PCI, SOC 2) as a default, not an upsell.
- Junior or mid-level developers assigned to your project
- Hourly billing with no cap on total cost
- No compliance expertise -- you pay for audits later
- Boilerplate code with minimal testing
- Deliverables in 16-24 weeks -- if on schedule
- No code ownership clause -- IP disputes common
- Senior engineers with 10+ years of backend experience
- Fixed price locked in at Roadmap phase (week 2)
- HIPAA, PCI-DSS, SOC 2 built into the architecture
- Microservices, automated tests, CI/CD from day one
- 8-12 week MVPs with clear milestones
- You own full source code and all documentation
How IRPR builds your backend with senior developers
A repeatable process that eliminates surprises and aligns with your timeline.
Every engagement starts with a 1-2 week Discovery phase where our senior backend development developers audit your current system, define API contracts, and map data flows. No assumptions, no guesswork.
Then we move into the Roadmap phase where we produce a detailed plan, fixed price, and timeline. Build and Release follow with weekly demos and automated deployment to your cloud account.
Deliverables you get with every backend project
No black boxes. You receive everything needed to run and maintain the system.
Every project ships with a complete set of artifacts that let your team take over or continue development. Our senior backend development developers document every decision so you never lose context.
We deploy to your AWS or Azure account from day one. You control all infrastructure and data. No vendor lock-in.
- Full source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions or CircleCI
- PostgreSQL schema design with migrations
- API documentation via Swagger/OpenAPI
- Unit and integration tests with 90%+ coverage
- Error tracking with Sentry and performance monitoring with Datadog
- Docker Compose and Kubernetes deployment files
- Security audit report including penetration testing results
- Compliance attestation (HIPAA, PCI, SOC 2) if required
- One-week post-launch support and knowledge transfer session
What we ship in this practice.
Real-time payment processing platform
Built a PCI-compliant backend that processes 2,000 transactions per minute using Go, PostgreSQL, and Stripe. Reduced declined transactions by 15% through intelligent retry logic. Industry: Fintech.
Healthcare API middleware
Developed a HIPAA-compliant API layer between a telemedicine app and multiple EHR providers. Handles 50K patient records daily with 200ms average latency. Tech stack: Node.js, Redis, AWS Lambda. Industry: Healthcare.
SaaS subscription billing system
Engineered a multi-tenant billing engine that manages 10K+ active subscriptions with proration, coupons, and dunning. Integrated Stripe and Avalara for tax compliance. Industry: SaaS.
Ecommerce inventory API
Designed a real-time inventory service that syncs across 3 warehouses and 2 marketplaces. Cut inventory reconciliation time from 4 hours to 10 minutes. Tech stack: Python, MongoDB, RabbitMQ. Industry: Ecommerce.
Logistics tracking system
Created a backend that tracks 50K+ packages per day with driver assignment and ETA calculation. Used Kafka for event streaming and PostgreSQL for persistent storage. Industry: Logistics.
Social media content API
Built a content moderation and scheduling API that processes 1M user-generated posts per month. Integrated OpenAI for content flagging and Redis for caching. Industry: Media.
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
All IRPR developers have 10+ years of backend experience. We don't outsource to junior or mid-level engineers. Every commit is reviewed by a senior backend development developer.
Compliance built-in
HIPAA, PCI-DSS, and SOC 2 controls are part of our standard architecture, not an add-on. We set up encrypted databases, audit logs, and role-based access from sprint one.
8-12 week MVPs with clear milestones
We break your backend into 2-week sprints with demonstrable outputs. You see a working API, database schema, or microservice every sprint, not just at the end.
Full code ownership
You own the entire codebase, infrastructure configs, and documentation. IRPR holds no IP. You can take the code to any team after the project ends.
1-2 week kickoff with async-first communication
We start within two weeks of contract signing. Our team works in your time zone overlap hours and uses Slack, Jira, and weekly video calls to keep everyone aligned.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
