With over 15 years of experience I understand many aspects that goes into a website. From UX to design to development, all 3 must work hand in hand.
Angular 4, Vue, Node, Socket.io, Typescript, Ionic 2, Cordova, React, PHP, Laravel, Statamic, Wordpress, CSS, HTML, Gunt, Gulp, Webpack, Rollup and many APIs (I have an addiction to them). These change often as I'm always learning new things.
I also have a lot of experience with ecommerce. From custom product data to shipping fulfillment, utilizing many payment services, such as Stripe, Authorize.net (certified developer), TrustCommerce, Shopify, Square and more.
