I started public speaking in elementary school, but went an extended hiatus after a failed presentation in Grade 6.  While I learned a valuable lesson during that failure of catering to your audience, I hesitated from giving more speeches after that failure.  Recently I started presenting talks at the meetups and at work, and I found that I enjoyed giving talks more than my fear of presenting publicly.  Below I’ve listed links to the slides and presentation material used in my recent talks.
