The Challenge

Dealers needed a modern, fast e-commerce experience for selling outboard motors nationwide — one that could carry product data, inventory, and marketing across a headless architecture instead of a stock template.

  • Product and inventory synchronization across systems
  • Lizzy integration workflows connecting business platforms
  • Shipping and product-purchasing logic
  • Google Analytics 4 and Google Ads conversion tracking

The Challenge

A certified forensic document examiner needed a professional web presence to build credibility with attorneys, courts, and private clients — and to be found in search across three separate state markets.

What I Built

  • Complete branding and website design, in collaboration with the client
  • Responsive Next.js site built from concept through production
  • Regional SEO landing pages for Kentucky and Ohio markets
  • Sitemap and Google Search Console setup

Dutch Craft Mattress

Modernized marketing site for a family-owned mattress manufacturer

Next.js · TypeScript · Tailwind CSS · Vercel

Homepage

The Challenge

A 20-year-old mattress manufacturer's site no longer matched the quality of the product — the brand needed a modern redesign that could scale as the product catalog grew.

What I Built

  • Full redesign and modernization using Next.js and Tailwind CSS
  • Reusable, scalable component architecture
  • Responsive product collection pages across 8 mattress lines
  • Improved navigation and overall user experience
  • Foundation laid for future e-commerce functionality

About

More than a developer — I work at the intersection of technology, business, and digital operations.

My role extends beyond building websites — I solve real operational problems, connect platforms, improve customer experiences, support marketing initiatives, and manage the systems businesses rely on every day.

I'm especially experienced in Next.js, TypeScript, Shopify, API integrations, technical SEO, analytics, and translating business needs into practical digital solutions.
