Why senior b2b web development developers matter
B2B web applications have complex requirements that junior developers cannot handle.
B2B apps need multi-tenant data isolation, role-based access control, and integrations with enterprise tools like Salesforce, HubSpot, and QuickBooks. Our senior b2b web development developers have built 200+ such systems across 50 countries. They know how to design databases for scale and write code that passes SOC 2 audits.
A junior developer might take 16 weeks to build a basic CRM. Our team delivers a production-ready B2B platform in 8-12 weeks with automated testing, CI/CD, and 99.9% uptime. We use React, Node.js, and PostgreSQL on AWS. Every project includes a fixed price and a clear roadmap.
How IRPR differs from generic dev shops
Most agencies assign junior developers to B2B projects. IRPR does not.
Generic dev shops often staff projects with junior developers who learn on your dime. They charge hourly, so scope creep costs you more. They rarely deliver on time. And they hand over code with no documentation or CI/CD pipeline.
IRPR assigns only senior b2b web development developers with 8+ years of experience. We give you a fixed price in week 2 during the Roadmap phase. We ship in 8-12 weeks with full documentation, automated tests, and a CI/CD pipeline on GitHub Actions. You own the code from day one.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- No fixed timeline
- No documentation
- No CI/CD pipeline
- Code ownership unclear
- Senior developers with 8+ years experience
- Fixed price from week 2
- 8-12 week delivery
- Full documentation included
- CI/CD on GitHub Actions
- You own all source code
Our process for building B2B web applications
We follow a four-phase process that de-risks your project from day one.
Every B2B web project starts with a 2-week Roadmap phase. We define the architecture, tech stack, and user stories. You get a fixed price and a detailed timeline. No surprises.
Then we build the MVP in 8-12 weeks using React, Node.js, and PostgreSQL. We deploy to AWS with automated scaling. You get a production-ready application with CI/CD, monitoring, and documentation.
What ships with every B2B web project
You get more than just code. Every project includes these deliverables.
We believe in full transparency. You own everything we build. No black boxes, no hidden fees, no vendor lock-in.
Every project includes source code, infrastructure as code, CI/CD pipelines, and documentation. You can take the code to any team after launch.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions
- Infrastructure as code with Terraform on AWS
- Sentry error tracking and monitoring
- PostgreSQL database with migrations
- API documentation with Swagger
- User documentation and admin guide
- 30 days of post-launch support
- Admin access to all cloud accounts
- Fixed price contract with no hourly billing
