Hi! I'm Lianjie Guo / 郭廉杰
I am currently a second-year M.S. student at FAST-Lab, Zhejiang University, advised by Prof. Fei Gao. Before that, I received my B.Eng. degree from the School of Automation, Northwestern Polytechnical University.
I enjoy Robotics and 3D Vision, and I am now spending most of my time on Generative AI. Previously, I worked on robot navigation and built simulation environments for navigation research.
Along the way, I enjoy building open-source infrastructure tools and growing into a full-stack engineer who can turn ambitious ideas into cool, reliable, and useful systems.

Open-Source Projects
Friendly-Splat
FriendlySplat is a user-friendly and clean Gaussian Splatting codebase, integrating SOTA features into a unified platform for training, pruning, meshing and segmentation. It is currently under construction.
PackForcing-Unofficial
This is an unofficial implementation of PackForcing, built as a personal study project to better understand PackForcing and the broader "Forcing" family of long-video generation methods. Built for fun and study.
