• Morningstar Data Package: A python package that provided the users with function to manipulate stock data, having features to filter, format and manipulate such data. The team was also in charge on a python API that retrieve the data from multiple source and unified the responses.

• Analytics Lab: A data science tool based on an open source platform called JupyterLab, where data scientists could make use of jupyter python notebooks for their day to day tasks. It provided plug-ins where users could retrieve data and use it in the notebooks by dragging them from the interface to the notebook cells, the corresponding python code was generated then. These plug-ins by default could be created with React, which is JupyterLab's default. Eventually they had to be migrated to Vue due to the client having a UI components library built in it and wanting to make its applications UI consistent. JupyterLab also allows the creation of server side extensions based on python, and we created a fair share of endpoints for authentication, and data fetching.
