Why hire senior custom web app development developers?
Senior developers build better software faster, with fewer bugs and lower total cost.
IRPR's senior engineers average 10+ years of experience. They have shipped over 200 products across 50 countries. Every developer knows React, Node.js, and cloud infrastructure.
You get a dedicated team that writes code, sets up CI/CD, and deploys to production. No handoffs, no junior devs learning on your project.
The difference between generic dev shops and IRPR
Not all development teams deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often assign junior developers, use hourly billing, and have no compliance experience. That leads to budget overruns and technical debt.
IRPR assigns only senior engineers, fixes the price after the Roadmap, and builds compliance into every project from day one.
- Junior developers learning on your project
- Hourly billing with no cap
- No compliance experience (HIPAA, PCI-DSS)
- Unclear timelines and scope creep
- Code ownership often disputed
- Minimal testing and documentation
- Senior engineers with 10+ years experience
- Fixed price from week 2 of Roadmap phase
- HIPAA, PCI-DSS, SOC 2 built in
- 8-12 week guaranteed timeline
- You own 100% of the code
- Automated testing, CI/CD, and Sentry monitoring
How we build your custom web app with senior developers
A proven 4-phase process that de-risks your project from idea to launch.
We start with a 1-week Idea phase to validate your concept. Then the Roadmap phase produces a fixed-price contract with a detailed scope.
The Product phase is where senior engineers build your app in 8-12 weeks. Release includes deployment, monitoring, and a 30-day support window.
What ships with your custom web app from IRPR
You get a production-ready web app with full ownership and all the tooling to run it.
Every project includes source code, infrastructure, and documentation. No hidden handoffs.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- Sentry error tracking and performance monitoring
- AWS or GCP infrastructure as code (Terraform)
- PostgreSQL database schema with migrations
- Stripe or payment gateway integration code
- Unit tests with Jest and integration tests
- API documentation (OpenAPI/Swagger)
- Admin dashboard for managing users and data
