Data Scientist. AI Orchestrator. Storyteller.

Welcome!

Welcome aboard! Hi, I’m Dong-in, but you can call me Don. I’m someone who loves trying new things and exploring new challenges. Lately, I’ve been really into boxing and hiking. Take a look around and get to know me better!

About Me

I am a passionate Data Scientist skilled in full-cycle data science project—from building models to delivering insights. With over 6 years of experience, I have consistently delivered impactful solutions that drive decision-making and improve operational efficiency. Based in Seoul, South Korea, I have been instrumental in handling large-scale data for platforms serving over 20 million monthly active users and processing millions of daily transactions.

I specialize in machine learning and deep learning, using tools like TensorFlow, PyTorch, and scikit-learn to develop predictive models. My expertise extends to data visualization, with proficiency in Tableau and Seaborn, helping to turn complex data into actionable insights. Additionally, I have experience in time series analysis and natural language processing using techniques such as LSTM and Transformers.

Recently, I completed a Proof of Concept (PoC) project with AWS, utilizing Retrieval-Augmented Generation (RAG) and Large Language Models (LLMs) to explore innovative AI applications in business scenarios. I am also deeply interested in Explainable AI (XAI) and Multi-modal AI, having applied various interpretability techniques while exploring innovative applications that combine different data modalities.
