About Rafael

I bring a unique combination: executive sales experience, strategic business vision, and practical specialization in eCommerce, Shopify, automation, and AI.
After a professional career in companies like Fujitsu, Samsung, and LG, managing large accounts and demanding distribution channels, I've been working in e-commerce since 2008, supporting brands in the creation, optimization, and evolution of their online stores.
My current specialization focuses on Shopify and everything that surrounds a solid eCommerce operation: store architecture, user experience, conversion optimization, SEO/GEO positioning, process automation, and the application of artificial intelligence to key digital business tasks.
I have knowledge in Liquid, HTML, JavaScript, React, UX, UI, and Google AI Studio, allowing me to intervene at both the strategic and execution levels. I work with a vision oriented towards profitability, efficiency, and scalability, always ensuring that the online store responds to real business objectives and not just aesthetic or technical criteria.
I am also the founder of Asellor, an agency specializing in end-to-end growth on Shopify, from which I develop solutions for brands that need a partner with commercial acumen, technical capability, and a clear results orientation.

Experience

  • Fujitsu (Eurofred)
    Sales Manager
    RETAIL (LARGE RETAILERS)
    September 1997 - November 2000 (3 years and 2 months)
    Madrid, Spain
    Sales Manager | Fujitsu / Eurofred
    September 1997 – November 2000
    I began a key stage of my career as Sales Manager in the white goods division of Fujitsu / Eurofred, taking responsibility for the commercial management of strategic channels and key accounts in the national market. During this period, I worked with top-tier players such as MediaMarkt, El Corte Inglés, and buying groups like Expert, developing business, negotiating commercial agreements, and consolidating long-term relationships in high-demand environments.
    This experience provided me with a solid foundation in consultative selling, key account negotiation, commercial strategy, and a deep understanding of how to build a competitive offering for real markets. This is a vision that I now apply to the digital environment to help brands and businesses sell better, with more structure and a greater focus on results.

    July 2007 - December 2008 (1 year and 5 months)
    Madrid, Spain
    Sales Manager Professional Channel | LG Spain
    June 2007 – December 2008
    During my time at LG Spain, I held the position of Sales Manager for the professional white goods channel, responsible for business development and account management in an environment particularly focused on business, distribution, and brand growth. From this position, I worked on opening, consolidating, and monitoring opportunities within the professional channel, bringing a strategic vision and sales management focused on results.
    This experience further broadened my market knowledge, negotiation with key stakeholders, and the building of solid commercial relationships in highly competitive contexts. Having worked in leading companies in the sector allowed me to develop a deep understanding of how to position products, build trust in the channel, and translate commercial strategy into real growth, a foundation that I now apply in my work as an eCommerce and Shopify expert, helping businesses sell better with both a commercial and operational perspective.
  • Samsung
    Sales Manager
    RETAIL (LARGE RETAILERS)

    I continued my career as Sales Manager at Samsung Electronics Spain, also in the white goods division, managing the same strategic channels and national key accounts. My responsibility focused on driving commercial growth, strengthening brand presence, and negotiating with some of the main players in Spanish retail, including MediaMarkt, El Corte Inglés, and buying groups like Expert.
    Working for years with leading companies and top-tier accounts allowed me to develop a comprehensive business vision: not just from a sales perspective, but from the real logic that drives the market, the customer, and profitability. That experience is what makes the difference today in my work as an eCommerce expert, especially in Shopify, where I combine commercial vision, strategic focus, and conversion-oriented execution to help brands grow professionally.
