Hello,
As an experienced and skilled web developer with a strong command of technologies such as MySql, Docker, and *SQL (MySQL, PostgreSQL, Oracle), I believe that I can efficiently tackle the issues plaguing your Mariadb Galera setup. Throughout my career, I've successfully handled complex backend development tasks ensuring robust scalability without compromising the search/filter capabilities of applications. This experience will prove crucial while fixing your Galera setup issues to ensure efficient performance is maintained.
Moreover, my vast experience in web development languages like PHP (5/7/8), NodeJS, JavaScript (vanilla, jQuery, Vue.js) means that I not only possess the technical capabilities to fix your Galera setup but I can also easily navigate through any front-end complexities that might arise during the process. Symfony-based webscripts used in your existing system will also be my strong suite during this project.
In addition to technical expertise, my adherence to communication and client satisfaction has been paramount throughout my professional journey. Should you choose me for this project, rest assured you will be provided with quality work resulting in an optimized and issue-free Galera setup for your website. Your satisfaction is my ultimate goal!
