Hello, I'm excited to submit a proposal to enhance your NFT art generator by upgrading the backend and creating an intuitive front-end interface. For the backend, I will optimize the FFmpeg integration to improve art generation with layers. For the front end, I will develop a sleek React-based UI that allows users to easily configure and generate NFT collections without coding. Key features will include drag-and-drop layers, previewing, batch controls, and connectivity to marketplaces. This will transform your generator into a powerful no-code platform that makes NFT creation accessible to everyone. I'm confident my expertise in blockchain, smart contracts, and full-stack development makes me the ideal candidate for this project. Please let me know if you would like any additional details on my approach. I look forward to discussing this further and signing an NDA. Thank you for considering me. Warm Regards, Neeraj K.
