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. 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.

Again, Jani was professional in competing his tasks and communicated in a clear and understandable way. My project to install Sucuri firewall and CDN for our WordPress site required a lot of technical expertise to connect all the parts which Jani was able to do in a structured manner.
