Shopify SEO Expert for Sculpture Store

I am looking for a professional with experience in Shopify and SEO to resolve issues with my sculpture store.
I am seeking a proactive, creative individual with a strong aesthetic sense, capable of providing clear, concrete, and professional solutions.

Tasks to be completed:
1. Review and correct the store's structure:
Navigation, products, and collections.
Templates and themes to ensure full functionality on desktop and mobile.

2. Correct existing errors and incomplete functions.
Optimize technical SEO in Spanish and English:
Titles, descriptions, and metadata for products and pages.
Correct configuration of URLs, redirects, and sitemap.
Improve loading speed and compatibility with installed SEO apps.

Requirements:
Proven experience in Shopify and bilingual e-commerce SEO.
Ability to propose effective solutions, meet deadlines, and deliver high-quality results.
Aesthetic sensitivity to ensure the store reflects the quality of the artwork: a clean, elegant, and functional design, not a "mass-market consumer goods" style or garish colors.
Ability to propose effective solutions, present a step-by-step plan, and meet established deadlines.

Additional requirements:
Previous experience with online stores selling artistic products or projects with a gallery aesthetic.
You will be asked to provide a portfolio of previous work with measurable SEO results, including specific metrics and implemented improvements, and to describe your optimization process in a clear and structured manner.
