CV

Senior WooCommerce Architect | AI-Driven SEO & High-Load Solutions

I transform standard WordPress sites into high-profit business systems. My specialization is High-load WooCommerce and SEO automation. While others simply "stitch" plugins together, I engineer architectures that handle millions of products and drive organic traffic.

What I do for your business:

  • Custom WooCommerce: Developing complex plugins (B2B pricing, dynamic discounts, CRM integrations) with clean PHP 8.x code.

  • AI-Driven SEO (pSEO): Scaling traffic through automated generation of thousands of unique pages (Programmatic SEO) using Claude 3.5/GPT-4o.

  • Performance & Speed: Reaching the "Green Zone" in Core Web Vitals. Optimizing SQL queries and configuring Redis/Nginx.

  • Zero-Loss Migration: Server-to-server migration (Ubuntu/Nginx) with guaranteed SEO ranking preservation and zero downtime.

Why me?

  • Dev Speed: Thanks to my AI stack (Cursor, Claude), I deliver results 2x faster than traditional developers.

  • Transparency: Using GIT and providing clear reports on key metrics (Lighthouse, GSC).

  • Experience: Proven cases on high-load projects (e.g., automall.in.ua).
