Engineering notes for AI, simulation, and software systems.
Original project logs, tutorials, and reflections from building practical AI/ML, FEM, CAD/CAE, robotics, and data workflows.
My First Job Interview
A personal reflection on my first technical interview at a foreign company — lessons learned about preparation, English communication, and humility.
Deep-FEM-UAV-Wing Dev Log (2/2): Dataset Validation → GNN Training → FEM vs AI Comparison
Completing the surrogate model pipeline: validating 200 FEM cases, training GraphSAGE GNN, and building a side-by-side comparison dashboard. Includes performance analysis and lessons learned.
[Palantir Foundry] Titanic Survivor Prediction Project (2/2) — Model Training & Workshop Dashboard
Train a baseline model in Foundry Code Workspaces (JupyterLab), export predictions for Kaggle, and build a simple dashboard in Workshop using Ontology.
Deep-FEM-UAV-Wing Dev Log (1/2): Geometry → Meshing → FEM
A practical dev log of an end-to-end pipeline: parametric UAV wing generation in Blender, tetra volume meshing in Gmsh, linear static FEM in CalculiX, and a Gradio viewer for precomputed results.
My Engineering Blog Archive & Previous Works
A quick intro to my previous Korean technical blog (Tistory) covering ROS2, simulation, and programming notes.
[Palantir Foundry] Titanic Survivor Prediction Project (1/2) — Data Preprocessing
Using Palantir Foundry's no-code Pipeline Builder, we upload the Kaggle Titanic dataset, handle missing values, and perform feature engineering to get the data ready for modeling.
