🤖 Developer Profile

🛠 Tech Stack & Implementation Experience

• Physical AI & Simulation
  • Environment configuration and physical simulation using MuJoCo (e.g., HalfCheetah, inverted pendulum tasks).
  • Validation of robot control and autonomous driving scenarios leveraging Vision-Language-Action (VLA) pipelines such as vLLM, Qwen2.5-VL, and Gemma 3.
• 3D Reconstruction & SLAM
  • Implementation of 3D pipelines utilizing DUSt3R / MASt3R (by NAVER LABS Europe) and VGGT-SLAM.
  • Pipeline integration converting point cloud data into STL format 3D polygon meshes via Poisson Surface Reconstruction.
• Computer Vision & Optimization
  • Object detection tasks using YOLO11 / YOLO12. Implemented neutral traffic analysis logic tracking "Involved Vehicles" to avoid fault bias before signal verification.
  • Performance-focused code optimization under strict execution time (avoiding TLE) and memory limits in Kaggle.

💻 Hardware & Infrastructure

• Primary Machine: MacBook Pro (M5 Apple Silicon) — Local inference and optimization leveraging the MLX framework.
• Secondary Machine: Lenovo ThinkPad X1 Carbon Gen 3 (Linux Mint) — OS-level configuration and systems automation using Bash scripting.
• Cloud Infrastructure: Management of on-demand GPU resources for Kaggle competitions and continuous performance benchmarking.
