My experiences include: Performance optimization - To achieve a 90+ PageSpeed Insights mobile score and a GOOD rating in all Core Web Vitals metrics I migrate WordPress/WooCommerce websites to Gutenberg (preferred) or optimize sites made with other builders. Functionality customization - I'm an expert in WordPress/WooCommerce customization including custom fields and custom post types (Pods framework, HTML/CSS/JavaScript/PHP, themes/plugins customization). I'm an author of a private plugin to distribute WooCommerce product data (including availability) from a single vendor to authorized clients' sites based on a subscription model. Learning Management Systems Marketplaces Multilingual sites Animations (JavaScript and CSS) After 25+ years in business management in different industries, I came back to my original passion which is designing and coding systems, that support business and organizational processes. I chose WordPress as the platform that ensures top-level results most effectively - and never regretted the choice. WP gets even better every year. Usually, we achieve prompt and thorough mutual understanding with clients about their needs and often I'm able to contribute to the client's overall vision of the project. Thank you for visiting Codeable and reading my profile, let us get your project done together.

Jani was great to work with! We came to him with super low mobile/desktop speed and within a couple of days we were in the green at 90 & 99! I highly recommend his services and we'll definitely be back if we have any problems in the future.
