Madrid · Trondheim
Hi, I am Liang Ji —
I study Computer Science at UC3M Madrid and I’m currently on Erasmus in Trondheim, Norway, working on underwater-robot simulation with Vortex NTNU. This is where I write about what I build, break, and learn.

What I’m up to now
- Simulating underwater drones with ROS2, C++ and Stonefish.
- Exploring stereo camera and sonar data fusion.
- Studying distributed systems and compiler fundamentals.
- Keeping up my Norwegian survival phrases.
