hi,
As an experienced full-stack developer with particular expertise in OpenCart - including the specific version you're using (3.0.x) - I can bring my wide range of skills to bear on making your requested TNT extension work smoothly and reliably. This encompasses proficiency not only in JavaScript, PHP, HTML, and CSS, but also MySQL, all of which are vital for handling delivery rates accurately and speedily. The attachment you sent may be confusing to you, but having worked on diverse projects throughout my 10+ year career, including extensive web applications like ERPs and CRMs, I know how to decrypt and convert the content where necessary.
Not only will I provide functionality, but I will also ensure a user-friendly experience during installation and set up process ensuring this TNT extension is as seamless as possible for your customers to use. This involves bringing my application creation skills with Laravel, PHP, and not just OpenCart; but also UI/UX designing where I can enhance the interface resulting in simplified processes. As for reliability of my work, I have developed sites equivalent to social networking platform.
My ability to engage collaboratively allows me establish a rapport with the people i work with; i intend to do same with your customers by providing high quality work towards getting this project delivered within timeframe.
Let's connect!
Thanks
