The project will involve partially developing software and the exact scope of work can be discussed. The technology should be up to date, secure and reliable. The selected freelancer should have expertise with working with blockchain to deliver the project on time and budget. Ideally, the freelancer should have experience with developing private blockchain with medium complexity. Being familiar with the latest development techniques and having a portfolio of successful projects would be highly advantageous.
