I have experience managing Shopify and WordPress websites to include adding new/upgrading new features using Liquid/HTML/CSS/JS/jQuery/PHP or adjusting layout to Themes (CSS), resolving bugs within Themes, etc all through code or WordPress plugins. I work along with Shopify and WordPress theme users to assist in managing their website and streamline them to having a great E-Shop or Web Product! You can have a look at my portfolio to see websites I've worked on as well.
My self-taught experience with HTML/CSS/JS/jQuery and PHP spans over 2 years with key concepts like OOP, APIs, Code Optimization/SEO, Responsive Design, User End Security implementations (Captcha, Spam Prevention).
If you need assistance in setting up/maintaining/restructuring your Shopify/WordPress website, just let me know as I'm happy to help!
