Hey,
Just got a glimpsed of your requirement of "migrate magento 1.9 from crazydomains to Siteground, install updates, bug fix, etc". I can help you out with this.
Although I have 9-year experience in web design and development, even experienced in Magento, PHP, laravel, Code-igniter, Angular, React js, VueJS, NextJS, Symfony, Gatsby, HTML/CSS, JavaScript, D3.js, Bootstrap and other web technologies, I would like to get more details about the project.
Lets connect and discuss more about it in details.
Regards,
Santanu
