I started my career writing C++ code for equity trading systems at Morgan Stanley; I then went on to manage teams there, before transitioning to product management, working for a number of vendors and consulting companies within the financial services industry. I did a hard reset in June of 2019, when I returned to my coding roots, with a focus on software engineering in the data and machine learning ecosystem.
