Senior Backend App Development DevelopersBackend Developers
We build your backend with senior engineers who ship in 8-12 weeks. Fixed price, no surprises, full ownership.
IRPR builds production-grade backends for web and mobile apps. We use Node.js, Go, Python, AWS Lambda, PostgreSQL, Redis, and Docker to deliver scalable APIs and microservices.
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. You get the source code, CI/CD pipeline, and full documentation.
Founders with a validated idea hire us to build their MVP. CTOs outsource backend architecture to avoid hiring overhead. Product managers need a senior team to replace a stalled project. Enterprises require a compliant backend for a new product line.

Why You Need Senior Backend App Development Developers
A junior team will cost you more in the long run. Senior engineers ship faster and write code that scales.
IRPR only hires engineers with 7+ years of experience. Our senior backend developers have built systems that handle 1 million requests per day. They know when to use a monolith and when to split into microservices.
We have shipped 200+ products across 50 countries. Our on-time delivery rate is 98%. Every project includes a dedicated senior backend developer who owns the architecture from day one.
Generic Dev Shop vs IRPR Senior Backend Developers
Most agencies staff juniors and bill hourly. IRPR assigns senior engineers and quotes a fixed price.
A generic dev shop may charge $40K for a backend that crashes under load. Their engineers learn on your dime. You pay for their mistakes.
IRPR senior backend developers have built payment systems for fintech and patient data pipelines for healthcare. We quote a fixed price after a 2-week Roadmap phase. No hourly billing. No scope creep.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No dedicated architect
- Late delivery, scope creep
- No compliance knowledge
- Code may not be production-ready
- Senior engineers with 7+ years experience
- Fixed price from Roadmap phase (week 2)
- Dedicated backend architect on every project
- 8-12 week timeline, 98% on-time
- HIPAA, PCI-DSS, SOC 2 built in
- Source code, CI/CD, and docs delivered
Our Backend Development Process
We follow a 4-phase framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables.
Phase 1 (Idea) takes 1 week. We review your requirements, existing code, and compliance needs. Phase 2 (Roadmap) takes 1 week. We produce a detailed spec, architecture diagram, and fixed price quote.
Phase 3 (Product) takes 8-12 weeks. Our senior backend developers build the backend in 2-week sprints. You see progress every sprint. Phase 4 (Release) includes deployment, monitoring setup, and a 30-day warranty.
What Ships with Your Backend
You own everything. Source code, infrastructure, and documentation.
We deliver a production-ready backend with CI/CD, monitoring, and automated tests. No black boxes. No locked-in tools.
Your team can take over immediately. We document every endpoint, every environment variable, and every deployment step.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Dockerized services with docker-compose
- API documentation (Swagger or Postman)
- Database schema and migration scripts
- Unit and integration tests (80%+ coverage)
- Sentry error tracking and Datadog monitoring
- Deployment playbook and runbook
- Architecture diagram (Draw.io or LucidChart)
- 30-day post-release support
