Hello & Greetings,
This is a very interesting project and right up my alley.
I am an expert in Javascript, AJAX, JQuery, various keyboard events (required for editor) and creating cross platform and responsive applications using these. I will create a robust and efficient editor (can develop it with or without using a JS framework).
I will try to provide a very cross-platform solution (working on iphone/android, windows mobile) for this.
I tend to write clean and modular code which is easy to extend and maintain.
Thanks & looking forward,
JP
