Hi! As an experienced Blockchain developer, I've 4 years of great experience in Smart contract and solidity. I'll spend much time fully understanding your project, needs, and wants before beginning the project so that I can assist you perfectly. This approach will allow for MUCH higher quality work! ✔ Solidity | Smart Contract | ERC721 ✔ JavaScript (ES5/ES6) | Typescript ✔ Bootstrap | Tailwind CSS Not only I can immediately get to the heart of the problem, but I also suggest ways you can fix it with much less money and effort than you had anticipated. Could you tell me more about your project? Looking forward to your response. Best regards Amr
