Freelancer needed to build a timeline app with Prosemirror editor

Hi experts, I am looking for someone to develop an app which basically looks like this:

  1. It shows two panes side by side. The left pane shows a time line of events. The right pane is a prosemirror-based editor to show the details of currently selected item on the left pane.
  2. It has strong search functions: search by a combination of date range, tags (multiple) and keywords.
  3. The right pane is a simple editor that can correctly render markdown codes, such as: headings, bullet points, webpage hyperlinks, image host links.
  4. Currently only web edition is needed. Preferably it can be deployed on a NAS (Synology.) If interested, you may reach me via
