Woo jonghyun
Software Engineer
Summary
👤
SeniorJeonghyun Woo is a PhD researcher and embedded-systems-savvy security engineer with 10 years of experience focused on computer architecture, memory systems, and hardware/security research. Based at UBC and advised by Prof. Prashant Nair, he blends academic rigor with hands-on firmware and front-end work—contributing firmware and sensor-block support to Entry Labs’ EntryJS and JS_Shield projects that bridge education-focused visual programming with IoT hardware. His internships at NVIDIA and Micron underscore practical experience optimizing memory- and system-level behavior in industry settings. A top-of-class graduate from Hanyang University, he pairs strong teaching experience in computer architecture with ongoing PhD research, and quietly combines low-level device control skills with higher-level tooling to make hardware security research reproducible and educational.

entryjs is visual programming editor for education
Role in this project:Front-end Developer
Front-end DeveloperContributions:11 commits, 11 PRs, 4 comments in 1 year 6 months
Contributions summary:Woo primarily focused on updating and expanding the block functionalities for the EntryJS visual programming editor. Their contributions include adding new blocks related to hardware interaction, specifically for the Joystick sensor shield, as well as integrating various sensor functionalities like NeoPixel LEDs, DHT temperature and humidity sensors, and a PMSensor. Furthermore, they modified and refactored existing blocks, adding features and improving the user interface for hardware control in the visual programming environment. This suggests an effort to enhance the educational tools available within EntryJS.
