smart contract and DAPP editing

I'm looking for an expert editor with extensive knowledge in smart contracts and DAPP editing. This is a more specialized project so I'm in need of someone with a deep understanding of the field. The editing required includes functionality enhancements for an already existing product. It needs to be completed in a timely manner so a rigid timeline needs to be respected. If you feel confident that you have the expertise and you are able to commit to the timeline, I'd love to hear from you.
