About Me

As a JavaScript geek, I love JavaScript and worked a lot with JavaScript based frameworks and libraries. Especially I have got rich experience with JavaScript based SPA such as React, Vue and Angular recently. I have also worked with other languages such as PHP (mostly Laravel), Python (mostly Django) and e-commerce platforms such as Shopify and WooCommerce.
