I have been an avid R user since 2010. I have used R both in the classroom as a data scientist and always fascinated by how easy and intuitive you can teach it to others.
As a daily Python user now, its structured programming, functional programming patterns and object-oriented programming is unpararelled comparing to R.
I have strong business sense which allows me to apply appropraite data science approach to different real-world problems. Building a fairly complex machine learning models is easily nowadays, but when dealing with real business problems, sometimes all you need is the simplest solution. (An Example)
I love exploring, analyzing, and visulizaing data.
ggiraph are my favorrate R visulization packages. I believe that one good chart can tell much better story than a 5 page report if you done it correctly.
Nothing is more enjoyable than sharing your knowledge. I have been teaching and mentoring junior data scientist over the last couple of years and I enjoyed every moment of those.
I am been an active investor in equity market since 2013. Finding out-performing stocks is like real world treasure hunt, you will always learn a lesson whether successful or not.
