Hi，我是章坚，目前就职于江苏移动的人工智能团队。在此之前，我曾就职于英特尔和阿里，在英特尔，我担任人工智能构架工程师。主要负责基于分布式框架Ray的大语言模型预训练与微调。在阿里，我担任高级算法工程师，研究方向是：基于神经渲染的3D重建技术。作为Object Drawer项目的主要成员，负责重建算法的开发与优化。
我在美丽的六朝古都南京，完成了本科以及研究生的学业，我遇见了“止于至善”的东南大学以及“诚朴雄伟”的南京大学。东大电子学院不仅有着严格的学业课程要求，同时还给我们创造了良好的工程技术条件。在南京大学ViSG实验室，我完成了“高精度语义地图的重建”项目，主要包含：基于激光雷达的位姿估计、场景重建以及场景理解。非常感谢周博、于博以及都教授的悉心指导。此外，我曾经在网易游戏实习，负责体素化场景的编辑与渲染。
个人的研究兴趣包括：深度学习、计算机视觉、计算机图形学以及机器人技术。此外，我一直保持着对技术的热情，不断学习并且跟进行最新的技术。

I’m Zhang Jian（章坚）, I graduated from Southeast University with a bachelor’s degree, and got my master degree from Nanjing University.
Previously, I was a senior algorithm engineer in Alibaba and focused on photo-realistic 3d reconstruction based on neural rendering. I was a member of object drawer project, which provides high-quality, low-cost 3d models for Taobao.
In addition, I was an intern at NetEase Games, responsible for editing and rendering of voxelized scenes. I also interned at D5 Render as a rendering engine engineer. During my bachelor degree, I mainly studied lidar-based pose estimation, scene reconstruction and understanding. My research interests include deep learning, computer vision, computer graphics and robotics. I always maintain a passion for technology, keep learning and catch up with latest technology.
