n8n Workflow Expert Needed to Automate Video Scheduling from Google Drive to Buffer

I’m looking for an experienced n8n automation expert to build a workflow that automatically uploads videos from Google Drive to Buffer, a social media scheduling tool. The workflow should detect new video files uploaded to a specific Google Drive folder and add each video to my Buffer posting queue automatically. The actual posting schedule is already configured inside Buffer, so the workflow only needs to add the videos to the queue. The workflow should: - Detect new video files from a selected Google Drive folder - Support video formats like MP4, MOV, and WEBM - Use one fixed/common caption for all videos - Add each video to Buffer’s existing social media posting queue - Work with one or multiple Buffer social media profiles - Prevent duplicate uploads using a Google Sheet log or similar method - Log each video’s status as queued, skipped, or failed - Handle errors without stopping the full batch - Include both a manual test trigger and an automated scheduled trigger Experience with n8n, Google Drive, Google Sheets, Buffer API, and social media automation is preferred. Please share examples of similar automation workflows you have built.
