🔹 Ecommerce Website Development | 🔹 3D Product Configurator | 🔹 Interactive Landing Page
Consider me your CTO-as-a-Service: I design the blueprint, build the core, and scale the engine that drives your business growth.

✨ How I Built a 3D Solution that Scaled a Business by 174%
A client approached me for a performance overhaul of their Ecommerce Website. After analyzing the user journey, I proposed a strategic shift: moving beyond static pages to an Interactive 3D Website featuring a custom 3D Product Configurator built with Three.js.
As their Full Stack Developer, I ensured a high-performance launch. The impact was instant: passive visitors became active users. By replacing static content with an immersive experience using WebGL, we triggered a 174% surge in sales and a massive boost in retention within 4 months. This is how I turn technical complexity into a high-ROI business tool through professional Web Design.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
🔷 Scalable Systems & High-Level Architecture
Building a successful digital product starts with a solid foundation that only an experienced Full Stack Developer can provide. In my role as a specialist in PHP and Node.js, I design Scalable Infrastructure for high-load demands. By leveraging PostgreSQL and Supabase for data integrity and API Integration, I ensure your platform meets industry standards. Every Full Stack Developer must prioritize stability. Whether you need a custom CMS or a SaaS system, my approach ensures your business asset is both robust and flexible.
🔷 Immersive 3D Environments & WebGL Performance
To stand out, a brand needs custom interactive web experiences. From 3D WebGL components to animated storytelling sections, quizzes, calculators, and guided product tours, I design interactive diagrams and embeddable marketing assets. As a Full Stack Developer, I optimize React, Next.js, and Three.js for performance-focused responsive implementation, ensuring 60 FPS. I engineer the "wow-effect" for conversion using HTML/CSS/JS, GSAP, and Rive/SVG.
🔷 Strategic Ecommerce Development & Workflow Automation
I build conversion-focused Shopify and WooCommerce stores with SEO-ready structure, optimized checkout flows, and payment integrations. As a Full Stack Developer, I specialize in PHP, Laravel, and TypeScript to handle ecommerce migration, large product catalogs, and multi-market setups. Bridging front-end Web Design and back-end intelligence, I integrate referral/affiliate flows and analytics/tracking. I create an automated platform with mobile-first UX and Three.js visuals.
🔷 Full Stack Engineering & Rapid MVP Development
Success requires a specialist who accelerates time-to-market. I utilize a modern stack featuring React, Next.js, and Tailwind to build fast, high-converting landing pages for Meta/Google Ads. On the back-end, I leverage PHP and a flexible CMS for data management. My focus on Web Development allows us to launch quickly. As a pro in Web Design and UX & UI, I ensure your MVP is the beginning of a market-leading legacy.
🔷 AI-Driven Personalization & High-Conversion UX
Future-proof Ecommerce requires more than just code; it demands intelligent automation. As a Full Stack Developer, I integrate AI Integration workflows to create personalized shopping journeys that convert. By leveraging Node.js and TypeScript, I build smart recommendation engines and Shopify Apps that adapt to user behavior. My Web Development approach focuses on SEO and UX & UI excellence.
