What a senior B2B web app development studio delivers
You get a team of senior engineers who ship production-ready code on a fixed timeline.
Every project at IRPR is built by engineers with 10+ years of experience. We don't use junior developers or outsource to offshore teams. Your code is written by the same people who have built systems for Fortune 500 companies and high-growth startups.
Our process starts with a 2-week Roadmap phase where we define scope, architecture, and a fixed price. Then we build your MVP in 8-12 weeks. You get full ownership of the source code, CI/CD pipeline, and documentation.
How we differ from a generic development agency
Most agencies sell you junior hours. We sell you senior outcomes.
A generic dev shop might assign your project to a junior developer who learns on the job. You pay for their learning curve. Deadlines slip. Code quality suffers. You end up with technical debt that costs more to fix later.
IRPR assigns senior engineers from day one. Every developer on your project has built and shipped production systems before. We write tests, enforce code reviews, and deploy with CI/CD. Your project stays on schedule and on budget.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance knowledge (HIPAA, SOC 2, PCI)
- Code not documented or tested
- Offshore handoff after MVP
- No post-launch support
- Senior engineers with 10+ years experience
- Fixed price from the Roadmap phase
- Built-in HIPAA, SOC 2, PCI-DSS compliance
- Full test coverage and documentation
- Same team from MVP to production
- 12 months of maintenance included
The IRPR process for B2B web app development
We move from idea to production in four clear phases.
Our process is designed to eliminate surprises. You know the price, timeline, and deliverables before we write a line of code. Every phase ends with a sign-off so you stay in control.
We use agile sprints with weekly demos. You see progress every Friday. If priorities change, we adjust the backlog. No rigid waterfall, no scope creep.
What ships with your B2B web app
Every project includes these deliverables by default.
We don't cut corners. Everything listed below is included in the fixed price. No add-ons, no hidden fees.
Your team gets full access to all code, infrastructure, and documentation from day one.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite (unit, integration, e2e)
- Sentry error tracking and monitoring
- AWS or GCP infrastructure with Terraform
- API documentation with Swagger/OpenAPI
- Admin dashboard with user management
- Role-based access control (RBAC)
- 12 months of critical bug fixes
- Post-launch performance optimization

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we start building.
Senior engineers only
Every developer on your project has 10+ years of experience. We don't hire juniors or outsource. Your code is written by the same people who have built systems for Fortune 500 companies.
12-week delivery guarantee
We ship your MVP in 8-12 weeks or you pay less. Our average is 11 weeks across 200+ projects. We have a 98% on-time delivery rate.
Full code ownership
You own the source code, infrastructure, and IP from day one. No licensing fees, no lock-in. You can take the code to any team after launch.
Compliance built-in
We build HIPAA, SOC 2, and PCI-DSS compliance into every project. No retrofitting. Our engineers understand healthcare, finance, and data privacy regulations.
No offshore handoff
Your project stays with the same team from Roadmap to Release. We don't hand off to a cheaper team after MVP. You get consistent communication and code quality.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
