Hi, my name is Aleksa. As a seasoned web developer with 7+ years of experience, I have a solid foundation in handling complex projects just like yours. My extensive knowledge and proficiency in JavaScript, React.js, HTML, CSS and other relevant technologies make me a suitable candidate for your task. I'm well conversant with migration tasks and understand the significant changes that came with Material UI v5. My ability to adapt quickly and provide meticulous attention to detail will ensure no step is left incomplete.
I've already studied the changes indicated in the link, and I assure you a seamless upgrade from React 16 to React 17, while adjusting all the styling to match the new emotion library. Migration tasks are often challenging, but my skills and dexterity help simplify these complexities into straightforward solutions. I will closely examine your themes, verify their compatibility, and fix any discrepancies accordingly.
Moreover, my experience working with various version control systems like Git, as mentioned in your project description, instills confidence that I can comfortably make changes directly in your GitHub code repository. No zipped files necessary; just efficient improvements right where they count
