Alejandro G.

I help established ecommerce brands and business teams improve the systems they already rely on: Shopify stores, custom web applications, APIs and operational workflows. I'm Alex, a computer engineer based in Spain. My background combines web development, REST and SOAP APIs, systems management, and security and compliance work. I bring that technical perspective to projects where maintainability, clear requirements and reliable delivery matter. HOW I CAN HELP - Shopify and Shopify Plus: store redesigns, custom functionality and improvements to existing ecommerce experiences. - Custom development and API integrations: connect your website or application with the systems your team uses, with a defined data flow and documented handover. - AI and n8n workflow automation: implement practical workflows for business operations, with API integrations, review points and agreed test cases. - Loyalty and Wallet Marketing with Vuelvy: plan retention journeys and implement Apple Wallet and Google Wallet passes, rewards or membership experiences. Integration scope and platform requirements are agreed before implementation. I work with ecommerce, marketing and operations teams that need a technical partner for a defined project or ongoing improvements. We start with your current setup, the business problem and a clearly scoped first phase. You receive agreed deliverables, progress updates and documentation your team can use. My project history includes Shopify development and customization, with client feedback highlighting professionalism, reliability and quality. My wider professional experience includes security, risk management and compliance, which helps me assess dependencies and operational risks alongside implementation. Send me your current platform, the workflow or customer journey you want to improve, and your target timeline. I will help define the scope, dependencies and next step here on Upwork. Available for collaboration in English and Spanish.
