I like everything related to tech, statistical/machine learning, computer simulation and numerical optimization. Among other things. And cheesecakes.
I created for example the website you're visiting now, using HTML, Javascript, Ruby and Jekyll. For some of the other things that I created,
visit this page.
For more details about these tools, you can read my blog.
PS: Give a try to Techtonique web app, a tool designed to help you make informed, data-driven decisions using Mathematics, Statistics, Machine Learning, and Data Visualization
