Getting my hands dirty solving compatibility issues with good and bad code of other extension providers.Tech stack: PHP, JavaScript, MySql, ElasticSearch, Gulp, WebPack, C#.# Side projecthttps://osm.software/docs/framework/0.15/index.htmlI created Osm Framework (docs) - an open-source, insanely fast, unprecedentedly extensible, and fun to work with PHP 8 framework for creating modern Web applications:* Highlighted feature - PHP dynamic traits. It allows to inject your code in the beginning, in the end, or instead of any existing method. Even more, you can add new properties and methods to any existing class.* I've been building it in public, and it helped me to become more consistent, to write clear and precise documentation, to write unit tests and to run them automatically on GitHub, to deploy on Push.
