Why you need a senior custom backend development company
A junior team will cost you time and money. Senior engineers ship faster and cleaner.
IRPR only hires engineers with 10+ years of production experience. Our team has built backends for 200+ products across 50 countries. We use Node.js, Python, Go, Rust, PostgreSQL, and Redis. Every line of code is reviewed and tested.
We deliver in 8-12 weeks with fixed pricing. No hourly billing. No scope creep. You get a production-ready backend with CI/CD, monitoring, and documentation. 98% of our projects ship on time.
How IRPR is different from a generic dev shop
Most agencies hire juniors and bill hourly. We don't.
A generic dev shop assigns you a team of juniors learning on your dime. They bill hourly and stretch timelines. You end up with unmaintainable code and surprise invoices.
IRPR assigns senior engineers with 10+ years of experience. We give you a fixed price in week 2. We ship in 8-12 weeks. You own the code and the CI/CD pipeline from day one.
- Juniors with 0-2 years of experience
- Hourly billing with no cap
- No compliance expertise
- No CI/CD or monitoring
- Code is buggy and slow
- Timelines slip by months
- Senior engineers with 10+ years
- Fixed price from week 2
- HIPAA, PCI-DSS, SOC 2 compliance
- CI/CD with GitHub Actions and Sentry
- Production-ready, tested code
- 8-12 week delivery, 98% on time
Our backend development process
We build your backend in 4 phases. Each phase has a clear deliverable.
Phase 1 is the Roadmap. In 2 weeks we define the architecture, tech stack, and fixed price. You get a document with wireframes, data models, and API endpoints.
Phase 2 is the Build. We code the backend in 6-10 weeks. You get daily progress updates and access to the staging environment. Phase 3 is the Release. We deploy to production and set up monitoring. Phase 4 is the Handoff. We transfer all code, documentation, and credentials.
What ships with your backend
Every project includes these deliverables by default.
We don't just hand over code. You get a complete production system with monitoring, documentation, and deployment pipelines. Your team can start using it immediately.
All source code is in your private GitHub repo. We set up CI/CD with GitHub Actions, error tracking with Sentry, and uptime monitoring with Datadog. You get API documentation with Swagger and a runbook for operations.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Sentry error tracking
- Datadog uptime monitoring
- Swagger/OpenAPI documentation
- Postman collection for testing
- Database schema and migration scripts
- Environment configuration files
- Operations runbook
- One-week post-launch support
