Develop Next-Gen Whiteboard Application

We have the version 1 of the app here → https://analyze.agency/screenshot This contract is about taking version 1 code base and build version 2. Version 2 design of the app can be found here → https://www.figma.com/design/SjsND1Pu0v652HAPG7Gmhz/Screenshot-App?node-id=0-1&t=WuZWbIW03WzMkNl1-1 Version 2 is not only design change but also engineering and feature changes. From a performance standpoint version 1 its slow - clunky - buggy - does not look anywhere close to top performers like Lucidchart or Miro - We want our version 2 tool also to match the popular tools from a performance standpoint. We want to the tool to work on even a low configuration windows laptop. We want our whiteboard to be exported and imported using our own propriety format. We want our screenshot to be exported and imported using our own propriety format. Similar to how word doc can be saved and reopened and edited we want the same feature.
