The problem Annotation tool portal solves

It is used to annotate handwritten datasets. It prepares the segments with their ground truth values from the annotated dataset. It can also use to make segmentation for object detection in computer vision and also label the annotated object to make classes. In this portal, multiple users can work simultaneously.

Challenges I ran into

I have faced the following problems which were changeling to solve

1. Handling of a large dataset on cloud
2. Simultaneously working on the portal by multiple users
3. Time complexity to process segment on server
