I've done mostly web development with Python (Django) and JavaScript (React). Python is my go-to language for almost everything I do (being a work or pet project) and I've always worked with the latest versions (3.4, 3.5 & 3.6 being the inspiration for my talk). I'm a Python tutor in our company's academy and I really like to talk and share my knowledge both in "private" sessions, within our company teams, and conferences.
