ROBOTICS · APPLICATION ACTIVITY
Making movement programmable.
For an International STEAM Festival, I designed and built four functional robots, including humanoid and spider forms, exploring remote movement, slope climbing, and obstacle detection.
PROJECTS · BUILDING WITH PURPOSE
Projects.
I enjoy making ideas tangible — then improving them by paying attention to what works for another person.
SELECTED PROJECT · GEOMETRY & DESIGN
What happens when a sundial stops showing a useful shadow?
I explored curved shadow-receiving surfaces to address an equatorial sundial’s equinox blind spot. The utility-model patent names three co-inventors.

STUDENT TECHNOLOGY TEAM
Coordinating hardware and software.
As Director of Technology in the student council, I recruited team members and coordinated a smart food-cart project for a cafeteria pilot.
EARLIER HANDS-ON EXPLORATIONS
Where the habit of making began.
Childhood and school activity photographs—part of my learning history, separate from the projects above.
EARLY ELECTRONICS
Connecting parts and code
Hands-on builds help me connect an abstract idea to the way a system behaves.
FLIGHT · CONTROL
Learn through motion
Flight practice makes questions about movement, control, and feedback easier to observe.
DESIGN · MATERIALS
Build with my hands
Woodworking rewards care with sequence, force, and detail.
OBSERVE · RECORD
Start with what is measurable
Experiments remind me to notice carefully before I draw conclusions.
