Sergio Hernandez developed and delivered the Soju Coreano product line for the jseoanesleon/reto-2 repository, building a complete end-to-end storefront experience. He implemented the product’s catalog listing, a dedicated product detail page, and integrated the new SKU into the shopping and checkout flow. Using HTML, CSS, and JavaScript, Sergio focused on front-end development to ensure a seamless user journey from product discovery to purchase. All changes were tracked with clear, auditable commits, supporting maintainability. The work addressed the need for rapid SKU onboarding and improved conversion by presenting a cohesive product experience, though the scope was limited to a single feature.
