Senior High Converting Website Development ConsultantsWebsite Development
We build websites that turn visitors into buyers. Our senior engineers ship MVPs in 8-12 weeks with fixed pricing.
IRPR builds high converting websites using modern frameworks like Next.js, Vue.js, and React on the frontend with headless CMS (Contentful, Sanity) or ecommerce platforms (Shopify Plus, WooCommerce). Every site is optimized for page speed, mobile UX, and clear calls to action.
We ship a fully functional, conversion-focused website in 8-12 weeks for a fixed price between $80K and $250K, depending on complexity and integrations. Projects include A/B testing setup, analytics tracking (GA4, Hotjar), and compliance for HIPAA, PCI-DSS, or SOC 2 as needed.
Typical buyers are CTOs needing a scalable web presence, Heads of Digital looking to lift conversion rates, Marketing Directors who want a clear ROI from their site, and Founders launching a data-driven product landing page.

Why High Converting Websites Need Senior Consultants
Conversion rate improvements of 20-40% are typical when we apply data-backed design and personalization strategies.
IRPR's senior high converting website development consultants have shipped over 200 products across 50 countries. Every website we build starts with a conversion audit: we analyze current funnels, identify drop-off points, and design experiments to test hypotheses. The result is a site that drives measurable business outcomes.
Our fixed-price model means you know the cost upfront. We use tools like Hotjar session recordings, FullStory replays, and Google Analytics 4 to inform every design decision. Post-launch, we hand over full source code and provide documentation so your team can continue A/B testing independently.
How IRPR Differs from Generic Dev Shops
Most agencies focus on aesthetics. We focus on conversion rates and revenue impact.
Generic development shops often hand off a site without any conversion optimization strategy. They use hourly billing, which encourages scope creep. They lack the senior talent to make strategic decisions about UX and A/B testing.
IRPR assigns only senior engineers (10+ years experience) who act as consultants. We build for conversion from day one, using analytics and heatmaps to guide design. Our fixed pricing means no surprises.
- No conversion audit before build
- Hourly billing drives scope creep
- Junior or offshore developers
- No A/B testing infrastructure
- No post-launch performance tracking
- Code ownership unclear or withheld
- Conversion audit and funnel analysis first
- Fixed price from the Roadmap phase
- Senior engineers only (10+ years)
- Built-in A/B testing with Optimizely or Google Optimize
- Analytics setup (GA4, Hotjar, Sentry)
- Full source code ownership with no strings
Our Process for Building High Converting Websites
We move from idea to release in four structured phases, each with clear deliverables.
Phase 1 (Idea): We conduct a 2-week discovery sprint with stakeholder interviews, competitor analysis, and a conversion audit. You get a validated hypothesis for what will increase conversions.
Phase 2-4 (Roadmap, Product, Release): We produce a detailed roadmap, build the MVP in 8-12 weeks, and handle deployment with CI/CD pipelines. Every milestone includes performance benchmarking.
What Ships with Every High Converting Website
We don't just hand over code. You get a complete system for ongoing optimization.
Every project includes the deliverables listed below. These are not optional add-ons — they are part of the fixed price. Your team can take over immediately after launch.
We also provide a 30-day post-launch support period to fix any issues and help with your first round of A/B experiments.
- Source code in your private GitHub repo
- CI/CD pipeline via GitHub Actions or CircleCI
- Sentry error tracking and performance monitoring
- Google Analytics 4 plus Hotjar heatmaps
- A/B testing framework (Optimizely or Google Optimize)
- Responsive design tested on mobile and tablet
- Security audit (OWASP top 10 checks)
- Full documentation (architecture, deployment, testing)
- 30-day post-launch support with SLA
- Performance report (Lighthouse score >85)
