Leslie Kosier is a process-minded creative, with a background in photography and video production, who finds joy in solving problems for designers. Leslie joined musical.ly in early 2018 when it was still a small startup, before the company became TikTok later that year. She has had the privilege of building TikTok's Design Ops team from the ground-up, and considers her team to still be “in progress” as it continues to evolve out of its infancy. When not at work, Leslie enjoys playing card games, drinking wine, and attempting to grow her kitten's Instagram following.
