About me

Business-minded development, built around people.

From Hospitality to Code

I'm a results-driven Web Developer with a unique background in hospitality management. My journey from customer service excellence to software development has given me a distinctive perspective on creating user-centered solutions.

Currently working at Maxicare Healthcare Corporation as a Shopify Web Developer - Manager. I contributed to the initial team launch of its Shopify Plus storefront and now solely handle the site, including custom sections, Liquid theme development, checkout extensions, custom pages, Shopify admin operations, new features, and integrations.

Across Maxicare, Baytech BPO, and WeePay Payment Processing Corporation, I translate business needs into reliable e-commerce and enterprise solutions with clear communication and maintainable code.
