    PLEASE, DO NOT BID IF YOU ARE NOT THE DEVELOPER WHO WILL ACTUALLY CODE MY PROJECT. I designed the architecture (and the UI) of a multi-cryptocurrencies wallet. This wallet take the form of a Javascript website - using: . Functionalities already developed at sites like [url removed, login to view] and [url removed, login to view] . Design features of sites like [url removed, login to view] Since I am not a professional coder, I am looking for a developer to help me code my wallet in Javascript. Knowledge of how cryptocurrencies work is a plus - but is not mandatory (as I can help in that respect). I intend to work hand in hand with the developer (as a "co-developer") at every single stage of that project - and, for that purpose, if needs so, I am willing to relocate wherever the developer is located - for the length of my project (1-2 weeks for a developer proficient in javascript and design).
