I recently finished the Data Science Specialization offered by Coursera. It is a nine course sequence that covers all aspects of data science, from finding and cleaning data, to creating reproducible research, applying regression models and machine learning, and producing data products. The final class is called Developing Data Products and we were required to develop a project for it. For my project I created an interactive data visualization of data scientist jobs worldwide that I call “Where The Jobs Are”. The app processes data scientist job listings obtained from the Careerjet.com API, showing numbers of jobs and salary ranges in bar charts and box plots by region. Users can drill down one level by selecting the region and see jobs by city. They can also see job listing details and click through to the actual job advertisement.

The app is built with R and Shiny, while the Careerjet API is accessed with a Python script. Here are a couple of screenshots.

Enjoying Coursera

I started taking some MOOC‘s (massively open online courses) and have really enjoyed the offerings from Coursera.org. I recently completed the Introduction to Interactive Programming in Python course from Rice which concluded with a project that involved coding a version of the old arcade game Asteroids, but with fancier graphics than the original. Although a lot of the content was provided, like all the graphics and sound effects, the coding portion was still fun and interesting.

Currently I am taking Coursera’s Startup Engineering course from Standford. The syllabus is awesome – we pull together a bunch of software tools needed to code and deploy a web startup, including Linux command line, Git, AWS, Heroku and more. There is a final project that involves coding our app in node.js and trying to get it crowd funded. The course also includes a philisophocial portion with inputs from a number of sucessful Silicon Valley startup founders plus some great background reading. Many of the tools are new to me so it is going to be a challenge but I am really enjoying it so far and hope to get my idea working and deployed.
