This is me!

What I do

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.
