+## Files

+### POST /api/dms/upload-file
+- **Description**: Generates a signed URL for direct file upload to S3
+- **Method**: POST
+- **Content-Type**: multipart/form-data
+- **Request Body**:
+  ```json
+  {
+    "fileName": "example.pdf",
+    "fileType": "application/pdf"
+  }
+  ```
+- **Required Fields**: fileName, fileType
+- **Response Example**:
+  ```json
+  {
+    "status": 200,
+    "message": "Signed URL generated for file: example.pdf",
+    "signedUrl": "https://bucket-name.s3.region.amazonaws.com/..."
+  }
+  ```
+- **Error Responses**:
+  ```json
+  {
+    "status": 400,
+    "message": "Missing required fields { fileName, fileType }"
+  }
+  ```
+  ```json
+  {
+    "status": 500,
+    "message": "Failed to generate signed URL",
+    "error": "Error details..."
+  }
+  ```
+- **Notes**: 
+  - The signed URL expires after 60 seconds
+  - Use the returned signedUrl with a PUT request to upload the file directly to S3
+  - Include the file's Content-Type header when uploading to S3
