Jarritos
The site I built before its redesign: WordPress with a custom theme, custom fields, sliders and other custom elements. My signature is in the CSS file.
/* Jonathan Cortés — custom themes, plugins & integrations */
Senior Full Stack developer building websites that go beyond configuring a theme.
E-commerce, tourism, education, healthcare, manufacturing and informational websites, mostly with WordPress.
I’m a Software Engineer with a degree in Web Applications Development, working full stack in PHP and WordPress since 2012. Co-owner of the web development company Kintsugi Web Studio.
Most of my work involves custom WordPress themes, custom plugins, ACF, WooCommerce, JavaScript, PHP, APIs and custom integrations. I also have experience with Laravel and with projects that required much more than configuring an existing theme or plugin.
What I use every day, what I use often, and what I can get by with.
The company I worked for had a contract with Novamex, the company behind Jarritos, so I built the Jarritos site and several of their other websites. Some still contain my original code, including my signature in the CSS.
