Customizations, Full Website Builds, Performance Optimizations
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. I provide optimal configuration of the WP Rocket plugin. 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 the 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 (Learndash LMS, Tutor LMS) 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 evaluated and quickly solved issues with a custom plugin which would not run under PHP 8.0 if the website were to be upgraded from PHP 7.4. His communications were clear and helpful, and I look forward to working with Jani again.
