Electrum is an open source project under MIT License. You do not need to ask the developers to accept your C.V, you can FORK for the project and create a special copy or start writing an improvement and take a cue from the current sources. The only difference is that the new version will not be signed by Electrum developers, and then the person who trusts you is the one who will download it.
