ARTHROSCOPIC SURGERY SYSTEM
ARTHROSCOPIC
SURGERY
SYSTEM
Collaborated with Rejoin’s in-house engineers and medical experts to design and develop an arthroscopic surgery system from concept sketch to clinical use. The project involved user-centered research, ergonomic optimization, and iterative prototyping, ensuring functionality, safety, and ease of use in the operating room. A full-cycle industrial design process that transformed ideas on paper into a surgical tool ready for real-world application.

LASTGRAB F&B
APP
Where everything started. Back in 2016, I worked on Lastgrab, a restaurant recommendation app created by a Swedish startup. It was my first real dive into digital product design, covering everything from user flows and wireframes to interface design. Working on this project became the foundation for how I understand and approach design today.
