Data Science (YouTube Series) - 2017

From what’s been said, machines are said to replace the human workforce in the next coming decade. In this series, I will explain to you why this may not be the case. In fact, this whole series focuses on how to take a humanistic approach in teaching machines how to properly solve tasks with high effectiveness. This involves imparting on machines ethical values and our common understanding of the world. I will explain in depth what I mean by these ideas as I go through the series.

Past Projects

Secure URL Shortner Service - 2016

alt txt

An URL shortner is a service that basically renders a shorter url for the one being provided (usually long). In this project, we implemented this service in a secure way that allows users to auto-generate a short URL that is secure and shareable among users with proper permission. Additionally, authors and users with the proper permission are able to access a dashboard to obtain insights into the traffic information pertaining to the URL provided. For this classroom project we applied best practices in microservices architecture and service security to build both a secure API and front-end application.
