Experience 💼

Deep Learning Researcher @ KRAFTON Inc.
📍 Seoul, South Korea | Nov. 2022 - Present

  • Developed a scalable algorithm for collecting refined training data from large-scale 3D assets and worked with diffusion models using ControlNet and LoRA, enhancing the quality of multi-modal PBR texture generation.
  • Reduced mesh processing time from hours to seconds by designing an algorithm to convert unstructured meshes into watertight forms, reducing complexity from cubic to quadratic.
  • Optimized a 3D reconstruction model, generating game assets from a single photo in under 30 seconds on consumer devices. This was recognized as a top AI innovation for the upcoming flagship game, inZOI.

Machine Learning Engineer @ Spacewalk Inc.
📍 Seoul, South Korea | Jul. 2021 - Sep. 2022

  • Designed and deployed Point Transformer-based reinforcement learning algorithms (A3C, PPO) for optimizing building designs, improving profit maximization while complying with regulations.
  • Applied pairwise ranking learning for reward function tuning, reducing tuning time by 200x and increasing agreement with architect preferences from 55% to 90%, doubling AI outputs meeting human-quality standards to 60%.
