Build Custom Chromium

Hello We need a C++ developer with experience of creating and modifying Chromium. We need to simplify user experience. The task is: Remove the ui and the functionality around viewport. Only web viewport part of ui is required - menu, tabs, minimze, close buttons must not exists. New window or new tab (one of that) must be created also as only web viewport. It must be possible to resize window by mouse near with border of such window. It must be possible to move such window any way, (using mouse with ctrl or by middle button). It need to be done with minimal possible hacks in chrome code. The better way is application in chrome us it as library where possible. If you are not experienced (but in hope to solve the task) write that. Please write in proposal your C++ experience years and OS used. Thank you.
