I work for an insurance broker that manages several billion in assets. I do a lot of analysis and I have taught myself Python to solve analytical problems.
This is not a part of my official job function; it is just something I have done above and beyond because I am a curious fellow.
Most of the in-house analysis is done using Excel and extracting data from a database (don't ask - the database dev doesn't really know how to build a database...) and I just wanted to up my game. It makes me more effective at work and I run statistical analysis using pandas and numpy. I have started to look into machine learning as well. I make sure that none of this affects my day to day duties.
My question is, is listing these skills that I've developed on a résumé appropriate?
