Blockchain Specialist for Smart Contract Development

We will start the pre-sale of our project shortly. We need developers who can start work immediately and solve our problems quickly. All our contracts are ready, our contracts are integrated into our site, but there are problems in the frontend parts. We are looking for fully competent developers who can make contract integration, ui changes and contract edits if necessary. We have very limited time, we prefer to start working immediately with the person we agree with.
