    Hey, my name is Janko. I've been working as a full-stack developer for almost a decade. In my career, I worked on many web development projects (e-commerce, Web Apps, custom websites, platforms: Shopify, WordPress, Wix, Webflow). Last few years, I have been focused on Shopify development. Developed a lot of custom Shopify stores (start-to-finish), hundreds of custom sections and features, several custom Shopify apps, third-party integration, and migrated stores from other platforms to Shopify. For over three years, I was head of the development team - lead developer. Skilled in project management, team organization, and client communication, utilizing platforms like monday.com and Trello. Experienced in e-mail marketing (Klaviyo) and web analytics (GA4, GTM, Convert, HotJar), enhancing user experience and conversions. I often cooperated with web designers to adapt design files to fit platform limitations, timelines, and client requirements. One of my successful initiatives was mentorship - I was responsible for several young Junior developers and offered them my guidance, advice, and experience in this field. I am looking forward to new experiences and the opportunity to contribute with my knowledge. My skills: ⦁ Custom theme development (Liquid, HTML5, CSS3, JavaScript, Vue.js, jQuery...) ⦁ Custom app development (Node.js, React, Remix.js, MongoDB, AWS...) ⦁ Custom Webflow websites (HTML,CSS, JavaScript, jQuery, platform modules) ⦁ Analytics (GA4, GTM, Convert) ⦁ Email marketing (Klaviyo - custom form development) and custom email templates ⦁ UI/UX (Figma, Inkscape, InDesign, Illustrator) ⦁ Project and team management (monday.com, Slack)
