NextJS 10, MUI, Redux Template integrated into Shopify. Integration only, template already done. -- 2

I am looking for an experienced web developer to integrate a pre-made NextJS 10, Material-UI, and Redux template into a Shopify store. The programming language for the template is JavaScript, HTML and CSS, however, I am unsure if I’ll need it to be integrated with an existing Shopify theme or not. I do not need any additional components or features to be added. I do require that the integration is carried out professionally and efficiently, optimized and bug-free, and that it meets my shop's design and usability requirements. If you feel you have the necessary skillset and the drive to take on this task, please submit your proposal. Thank you!
