About

A cross-disciplinary engineer

From mechanics to robotics, from industry to AI — solving real-world problems at every step.

I'm Kevin Kou (寇宇), an MSc Robotics student at the Chinese University of Hong Kong (GPA 3.94/4.0, top 5%, Dean's List), with a BEng in Mechanical Engineering from Hefei University of Technology.

My career spans three fields: I spent 2.5 years at ABB Shanghai as a mechanical design engineer delivering cross-border BIW welding line projects, earning ABB Robotics China 2024 Top Performer. I then built a financial research multi-agent system during my internship at Sengital. Currently I'm an AI Product Manager at Bambu Lab, owning the after-sales ticket auto-reply Agent from design to production.

I believe great products come from deep problem understanding and relentless attention to detail. Whether it's a 24-node Agent workflow or a 100Hz robot control loop, I insist on data-driven decisions, test-verified quality, and result-oriented delivery.
