01 — About

Perception to action

I work where models meet motors — fine-tuning vision-language-action models, building physics-true simulations, and shipping the unglamorous systems code that makes robots actually work. From CUDA kernels to control loops, I care about the whole stack.

Robora
Robotics Simulation & ML Engineer
Shenzhen Robora Enterprise Ltd. · Shenzhen, China
Led simulation and ML infrastructure at a robotics startup — the VLA SDK, the physics environments, the 3D reconstruction pipeline, and the data tooling around them.
- Architected a VLA SDK for SmolVLA, π₀ / π₀.5, and GR00T N1.5 — inference plus PEFT fine-tuning (LoRA, QLoRA)
- Built multi-physics sim environments (PyBullet, MuJoCo, Gazebo) with PID, LQR, MPC, and RL control via SB3 / TorchRL
- Developed a 3D reconstruction toolkit — COLMAP, GLOMAP, 3D Gaussian Splatting — for ultra-realistic environment modeling
- Trained a YOLOv11 GDPR anonymization pipeline hitting 95%+ accuracy on faces and license plates
