Senior Web App Development Services by the Numbers
Every project ships with clear metrics that matter to your business.
IRPR has delivered 200+ web applications across 50+ countries. Our average MVP ships in 12 weeks with a fixed price. We maintain a 98% on-time delivery rate because every project is planned in the Roadmap phase (week 2).
Our apps handle production traffic from day one. We use AWS Auto Scaling to maintain 99.9% uptime. For fintech clients, we achieve PCI-DSS Level 1 certification. For healthcare, we pass HIPAA audits on first submission.
The Difference Between Generic Dev Shops and IRPR
Not all web app developers deliver the same result. Here is what sets us apart.
Most agencies assign junior developers to your project and bill by the hour. They use boilerplate code, skip testing, and hand over code you cannot maintain. IRPR works differently.
We staff senior engineers only, give you a fixed price before any code is written, and ship full ownership of the codebase. Every project includes CI/CD, error monitoring, and a 30-day warranty.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance certifications
- Code delivered without tests
- No CI/CD pipeline
- You do not own the IP
- Senior engineers with 10+ years average
- Fixed price from $80K
- HIPAA / PCI-DSS / SOC 2 compliant
- 100% test coverage on critical paths
- CI/CD on GitHub Actions + Sentry monitoring
- Full code ownership from day one
Our 4-Phase Web App Development Process
From idea to release in 12 weeks with no surprises.
Every project follows the same proven framework: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed timeline.
The Roadmap phase (week 2) produces a detailed scope, wireframes, and a fixed price. No changes after that. The Product phase (weeks 3-10) builds the app in 2-week sprints. The Release phase (weeks 11-12) deploys to production with monitoring.
What Ships with Every Senior Web App Development Project
Every deliverable is concrete. No black boxes.
When we finish a project, you get everything needed to run and maintain the app yourself. No vendor lock-in. No hidden dependencies.
Our standard delivery includes source code, infrastructure as code, monitoring, and documentation. You can deploy changes the same day we hand over the project.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking configured
- AWS or GCP infrastructure as Terraform
- PostgreSQL database with automated backups
- Unit and integration tests (80%+ coverage)
- Swagger/OpenAPI documentation
- Admin panel for managing users and content
- 30-day post-release warranty
- One-hour onboarding session for your team
