A Bit About Me!
I am a neuroscientist turned data scientist who loves discovering all that can be done with some data and a little (or big) bit of elbow grease. Here you will find a collection of my notes and projects covering a range of topics in data mining and web development. Being a perpetual tinkerer, I am always on the hunt for exciting ways to explore and create in Python and R. Along with Mihai Chelaru, I am also the co-curator of IntelligenceRefinery.io, a knowledge repository for all things data science and software development. If you have any questions, comments or suggestions, I would love to hear from you!
