Shopify Expert Developer | CRO, API & AI SaaS - 18+ Years Experience

I help Shopify businesses find where revenue, time, and customer confidence are being lost—and build the systems needed to fix those problems. I’m a Certified Shopify Expert, CRO Specialist, AI SaaS Engineer, and Full-Stack Developer with 18+ years of ecommerce experience. I have worked with 100+ businesses, including startups, established brands, wholesalers, manufacturers, and high-volume Shopify operations. Unlike developers who only complete coding tasks, I help businesses design, build, optimize, automate, and scale their complete ecommerce ecosystem. PROVEN ECOMMERCE GROWTH One of my strongest projects is CheapestTshirts Canada. I helped build and scale the business from $0 to approximately $1.5M in monthly sales within six months, contributing to an estimated $30M+ in gross revenue over approximately two years. This growth came from continuous CRO, UX improvements, multi-warehouse inventory, bulk ordering, shipping optimization, supplier integrations, backend automation, and operational scaling—not from one redesign or campaign. SHOPIFY DEVELOPMENT & ARCHITECTURE My Shopify experience includes: • Shopify and Shopify Plus • Shopify OS 2.0 and custom themes • Liquid, JavaScript, HTML, CSS, React and Next.js • Shopify apps, Functions, Flow and webhooks • Admin, Storefront and GraphQL APIs • Metafields, metaobjects and Shopify Markets • Subscriptions, bundles and memberships • Checkout customization • Multi-location inventory and warehouse ordering • Complex shipping and fulfillment logic • Supplier, ERP and third-party integrations • Product, pricing and inventory synchronization • Automated order processing • Platform migrations • Speed and Core Web Vitals optimization I have worked on Shopify systems supporting approximately 90,000 products, 4,000+ variant workflows, inventory across 10 warehouses, real-time supplier synchronization, custom bulk ordering, and automated fulfillment. CRO & ECOMMERCE GROWTH A good-looking website is not enough. Every design and development decision should help customers understand the offer, trust the business, and complete their purchase. My CRO work includes: • Customer psychology and user journeys • GA4, Microsoft Clarity and Hotjar • Heatmaps and session recordings • Funnel and abandonment analysis • Product and collection-page optimization • Navigation and product discovery • Landing pages and mobile UX • Cart and checkout friction • Trust signals and offer presentation • A/B testing strategy • Conversion rate, AOV and revenue-per-visitor improvement Unlike consultants who only provide recommendations, I can investigate the problem, define the strategy, design the solution, and personally implement it. AI SAAS & AUTOMATION I also build AI-powered SaaS platforms, dashboards, customer portals, subscription systems, and business automation. My stack includes React, Next.js, TypeScript, Tailwind CSS, Node.js, Supabase, PostgreSQL, REST APIs, GraphQL, Vercel, Cloudflare, GitHub and GitHub Actions. I regularly work with Claude, ChatGPT, OpenAI and Anthropic APIs, Claude Code, Cursor, v0, GitHub Copilot, and MCP-based workflows. AI accelerates research, analysis, development, and automation. My experience determines what matters commercially and how it should be implemented safely.

My goal is simple: Find the highest-impact problems, solve them in the correct order, and build systems that help the business grow.
