What I'm looking for

I’m looking for a role where I can blend full-stack engineering with digital strategy—owning e-commerce performance, SEO/SEM, and UX improvements—so we can build scalable systems that turn traffic into growth.

I’m a Digital Strategist and Full-Stack Developer with 17+ years of experience connecting technology, marketing, and e-commerce to drive measurable business growth. I specialize in building scalable digital ecosystems that connect strategy, design, and technology, and I bring hands-on expertise across Laravel, React, PHP/MySQL, Python, and multiple CMS platforms.

Right now, I manage and support multi-store Shopify e-commerce operations across regional storefronts, using Liquid, front-end engineering, and backend logic to resolve storefront issues, improve UX, and strengthen scalability and operational reliability. Previously, I led customer operations for 80+B2B accounts using tools like Salesforce, SAP, and Mocha (COMS), and I also shaped digital experiences through UX design work, SEO/SEM and paid media execution, and full-stack builds.
