Generic dev shop vs IRPR
Here is how we differ from typical development agencies.
Most agencies bill by the hour and hand off junior developers mid-project. IRPR assigns senior engineers from day one and delivers on a fixed price.
We ship production-ready code with full documentation, CI/CD, and monitoring. You own everything.
- Hourly billing with no cap
- Junior developers on your project
- No compliance expertise
- Code ownership unclear
- Scope creep without change orders
- No post-launch support
- Fixed price from $80K-$250K
- Senior engineers with 10+ years experience
- HIPAA, PCI-DSS, SOC 2 built-in
- Full source code ownership
- Roadmap phase locks scope
- 30 days of post-launch support
Our backend development process
We follow a proven 4-phase framework.
Every project starts with a 2-week Roadmap where we define the architecture, timeline, and fixed price. No guesswork.
We then build the backend in 8-12 weeks, testing and deploying continuously. You see progress every week.
What ships with every backend project
You get more than just code.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab
- Sentry error tracking and monitoring
- API documentation with Swagger/OpenAPI
- Database schema and migration scripts
- Docker containers and docker-compose files
- Terraform or CloudFormation infrastructure code
- Load testing results with k6 or Artillery
- Security audit report (SAST/DAST scan)
- 30 days of post-launch support and bug fixes
