Why work with a senior B2B web app development agency?
Mid-level and junior developers cost you time and money. A senior-only agency ships faster, with fewer bugs, and higher uptime.
At IRPR, every engineer has 10+ years of experience. We have shipped 200+ products across 50+ countries. Our teams are cross-functional: frontend, backend, DevOps, and QA. We write code that scales from day one.
We use a fixed-price model. You know the cost before we write a line of code. No hourly surprises. No scope creep. The average B2B web app takes 8-12 weeks from idea to deploy.
How we compare to generic development shops
Not all agencies are the same. Here is what you get with IRPR versus a typical offshore or full-stack generalist team.
Generic agencies often rely on junior developers. They use hourly billing and have high turnover. Communication is slow. Code quality is inconsistent. Security is an afterthought.
IRPR is different. Every engineer is senior. We work in your time zone with daily standups. We own the architecture and deployment. We deliver a CI/CD pipeline, monitoring, and documentation.
- Hourly billing with no cap
- Junior-heavy teams
- No dedicated QA
- Manual deployments
- No SLA for uptime
- Code ownership unclear
- Fixed price from week 2
- 100% senior engineers (10+ yrs)
- Automated testing & QA
- CI/CD on GitHub Actions
- 99.9% uptime SLA
- Full code ownership
Our 4-phase process for building B2B web apps
We do not start coding until the scope is locked. Here is exactly how we build your web application.
Phase 1: Idea. We map your requirements in a 2-day workshop. Phase 2: Roadmap. We deliver a detailed plan with timeline and fixed price. Phase 3: Build. Our engineers code in 2-week sprints. Phase 4: Release. We deploy to production and hand over everything.
Each phase has clear deliverables. You see progress every 14 days. We use Jira for tracking and Slack for daily communication. Average time to MVP: 8-12 weeks.
What ships with every B2B web app build
We do not just give you a code zip file. Every project includes the full production setup.
You get source code in your private GitHub repo, a CI/CD pipeline using GitHub Actions, and automated tests. We configure Sentry for error monitoring and Datadog for performance. Everything is deployed on AWS or GCP with Terraform.
We also provide Postman collections, API documentation, admin dashboard, and user role management. No hidden dependencies. You can maintain and extend the app with any team after launch.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated unit + integration tests
- Sentry error tracking configured
- Datadog performance monitoring
- Terraform infrastructure as code
- Postman API collection
- Admin dashboard with role-based access
- User authentication (Auth0 or custom)
