Developed and delivered the PHP-Mago Language Server Extension within the zed-industries/extensions repository, focusing on enhancing the PHP development workflow by introducing in-editor language support. This feature aimed to improve code completion, diagnostic accuracy, and navigation for PHP projects, laying the groundwork for future tooling enhancements. The implementation involved PHP development, submodule management, and effective use of version control systems, with changes tracked and committed through Git. By integrating TOML for configuration, the extension was prepared for broader adoption and seamless editor integration. The work emphasized maintainability and extensibility, providing a foundation for ongoing improvements in PHP developer productivity.
