Good Day :)
I have understood the idea of your Management system, where Doc will be uploaded from the team of any office and will be assigned randomly to a management person for review. The tracking and SMS system will also be there as a feature of this platform.
I have extensive knowledge of Core PHP and it's frameworks (Symfony, Laravel, Zend, CI, Cake), JS and it's Frameworks (React, Angular, Express, Backbone, Express, Node, Moment, Vue, Typescript, Go, 3, Gatsby), Ajax, HTML5, CSS3, jQuery, MySQL, Bootstrap, Nginx, ruby, rails, memes, Memcached GIT and Atlassian Tools.
Let's connect over chat to discuss further.
Thanks,
DA
