Looking for talented product designer

We are currently developing a sports app that combines the web and blockchain. We have already completed NitoGem, a basic demo version focused on the Web3 layer. NitoGem is already in service as a dApp, allowing users to register tokens and vote using ETH. Voting results directly impact rankings and exposure. The core system is already established, including wallet connectivity, smart contracts for voting and credit management, and an off-chain layer handling indexing and ranking logic. While it is currently operational, it is still in its early stages and requires improvements in terms of design and workflow. We are moving forward in a direction of evolution rather than a complete rebuild of the system. We plan to extend the same system beyond cryptocurrency to other fields, such as sports, where user engagement influences rankings and exposure in a similar manner. We will maintain the core mechanisms while gradually expanding use cases as the platform matures. We are looking for talented designers to help achieve these goals. If this project is successfully completed, we can develop a long-term partnership. It can be helpful you have knowledge of web3. When are you available to join? What are your strengths? If you are confident in this area, please feel free to contact us anytime. prefer European and US designer.
