I majored in mechanical engineering, but since graduation, I have been consistently reading and writing code. I am a Google AI/Cloud GDE and a Microsoft AI MVP. I run the TensorFlow blog (tensorflow.blog) and am interestingly exploring the boundaries between software and science by writing and translating books on machine learning and deep learning.

He has authored "Deep Learning from Scratch" (Hanbit Media, 2025), "Machine Learning + Deep Learning Alone (Revised Edition)" (Hanbit Media, 2025), "Data Analysis with Python Alone" (Hanbit Media, 2023), "The Art of Conversing with ChatGPT" (Hanbit Media, 2023), and "Do it! Introduction to Deep Learning" (Easys Publishing, 2019).
He has translated dozens of books into Korean, including "Large Language Models: Fast Track to the Core!" (Insight, 2025), "Machine Learning: Fast Track to the Core!" (Insight, 2025), "Learning LLMs by Building from Scratch" (Gilbut, 2025), "Hands-On LLMs" (Hanbit Media, 2025), "Machine Learning Q & AI" (Gilbut, 2025), "Mathematics for Developers" (Hanbit Media, 2024), "Machine Learning Pocket Reference with Python" (Hanbit Media, 2024), "Machine Learning with PyTorch and Scikit-Learn" (Gilbut, 2023), "What Is ChatGPT Doing ... and Why Does It Work?" (Hanbit Media, 2023), "Hands-On Machine Learning, 3rd Edition" (Hanbit Media, 2023), "Generative Deep Learning, 2nd Edition" (Hanbit Media, 2023), "Python for the Coding Brain" (Hanbit Media, 2023), "Natural Language Processing with Transformers" (Hanbit Media, 2022), "Deep Learning with Python, 2nd Edition" (Gilbut, 2022), "AI and Machine Learning for Coders" (Hanbit Media, 2022), "Hands-On Gradient Boosting with XGBoost and Scikit-Learn" (Hanbit Media, 2022), "Deep Learning with TensorFlow.js" (Gilbut, 2022), and "Introduction to Machine Learning with Python, 2nd Revised Edition" (Hanbit Media, 2022).
