I'm a quant trader working at a hedge fund. I write a lot of code, but not in the same way that I think most people here think about code. A lot of it is hacky Matlab scripts to test some new research idea. Some of it is hand-crafted C that implements some numerical routine that we need to call a few billion times. Occasionally I throw something together in Python to do some web scraping or parsing task, but that's becoming rarer nowadays.

I come to HN because I enjoy coding, and the level of discussion is still probably the best out of any online community I know of (excepting a few very specialized ones... the r/haskell community comes to mind).
