Hi there,
I am a Joomla expert and working on it for the last 8 years which includes highly customized themes, extensions, plugins, and components.
I have checked your job posting over here and I can assist you with the work you need.
Recently, I have updated php versions of 29 Joomla sites so I am aware with the issues and how to deal them.
Please share the Joomla Admin and cPanel details so I can check and work on it.
Looking forward to your positive response and a great working relationship.
Thank You
