Why senior high converting website development developers matter
Junior developers cost less but ship slower and break more. Senior developers build fast, convert better, and scale without rewrites.
A junior developer might take 16 weeks to build a site that converts at 2%. A senior engineer at IRPR builds the same site in 8 weeks with built-in A/B testing and conversion tracking. The site converts at 4% or higher from day one.
Our senior developers have shipped over 200 products across 50 countries. They know exactly which framework (Next.js, Remix, or Gatsby) and which tools (Hotjar, Google Optimize, Segment) to use for each conversion goal. No guesswork, no wasted sprints.
Generic dev shops vs IRPR senior developers
Most agencies send junior devs who learn on your dime. IRPR sends senior engineers who ship production-grade code from sprint one.
A generic dev shop might quote $50K but add 30% in change orders. They use WordPress and a page builder. You get a site that loads in 4 seconds and converts at 1.5%.
IRPR quotes a fixed price in week 2 after the Roadmap phase. We use Next.js, deploy on Vercel, and integrate A/B testing from the start. Your site loads under 1 second and converts at 3-5%.

How we build high converting websites
Our process has 4 phases. Each phase has a clear deliverable and a fixed price.
Phase 1 is the Idea phase where we map your conversion goals to technical requirements. Phase 2 is the Roadmap phase where we produce a detailed spec and a fixed price. Phase 3 is the Product phase where senior engineers build and test. Phase 4 is the Release phase where we deploy and monitor.
Every phase includes conversion rate optimization. We set up A/B tests, heatmaps, and funnel tracking before launch. You get data on day one, not after six months.
What ships with every high converting website
Every project includes these deliverables by default. No add-ons, no hidden fees.
You get source code in your GitHub repo, a CI/CD pipeline, and a staging environment. We also include a performance report and a conversion funnel analysis.
All projects ship with a Post-launch support period of 2 weeks. We fix any issues and monitor conversion metrics.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Staging and production environments
- A/B testing setup with Optimizely or VWO
- Heatmap and session recording with Hotjar
- Conversion funnel tracking with Google Analytics 4
- Lighthouse performance report (score 90+)
