I’m an AI/ML Engineer Intern at AIdanBio in Daejeon, South Korea, currently developing intelligent biomedical knowledge retrieval. I'm completing my B.E. in Electrical Engineering at Chungnam National University.
My work focuses on RAG pipelines, LangChain-based systems, and LLM-powered conversational AI — from vector search and prompt engineering to FastAPI backends and local model deployment with Ollama.
Research Interests
Retrieval-Augmented Generation (RAG); NLP; Prompt Engineering; LLM Evaluation; Conversational AI Systems; and efficient local LLM deployment.
Protein Structure Visualization Assistant
An intelligent assistant that interprets natural language queries to visualize 3D protein structures from the RCSB PDB. Integrates LLMs with a RAG pipeline for semantic understanding of protein documentation, and PyMOL for interactive rendering — enabling biomedical researchers to query structural data conversationally without writing visualization scripts.
System Architecture
Python · SVM · Scikit-learn · PCA
Supervised SVM classifier with StandardScaler preprocessing and GridSearchCV hyperparameter tuning. Evaluated via accuracy, confusion matrix, and F1 score. Decision boundaries visualized with PCA; best model pipeline serialized for reuse.
Python · K-means · Scikit-learn
Unsupervised K-means clustering on customer demographic data to identify actionable segments. Elbow method and silhouette analysis for optimal k selection. Trained model and scaler serialized for downstream deployment.
Python · NLP · TF-IDF · SVM · Logistic Regression
Multi-model text classifier with TF-IDF features across Naive Bayes, Logistic Regression, and SVM with GridSearchCV tuning. Evaluated with precision, recall, and F1. Model, vectorizer, and label encoder saved for deployment.
Python · NLP · VADER · BeautifulSoup
End-to-end sentiment pipeline for short quotes — scraped with requests and BeautifulSoup, labeled with VADER, trained with Naive Bayes and Logistic Regression. Evaluated with confusion matrices and word cloud visualizations.
