Feature Addition in PyGithub
While working on an open-source project named PyGithub, I developed a feature from scratch except for one minor commit.

Machine Comprehension Model

I created a machine learning model that can answer the questions from a given context. For example, a user can feed an article to the model and then ask an item from the section. The model will be able to answer the question with the correct context.

Search By Topics Feature in PyGithub
I added a search feature in the PyGithub API wrapper.

A Machine Comprehension Bot

I created an artificially intelligent bot to answer a question from a provided context. Under the hood of the application are Flask (a web framework in python) and Pytorch for calculating the answer to the specific question.

Since the application is hosted on free servers, sometimes a request might timeout which then exposes a worker-based API. Then a comprehension job can be queued and then the worker can be polled for the results once processing is complete.

Selenium Bug Fix
I added support for Geckodriver proxy settings in Python Selenium client bindings.
