I like turning practical problems into working systems, then revising the explanation until the idea is clear.

Information About Me

I build useful tools, then keep improving the argument behind them.

My HFI experience has been shaped by engineering clubs, campus-service platforms, robotics, and writing revision. The same pattern appears across my work: find a real constraint, build a practical response, test it with people, and refine the result.

I position myself as a technical builder with a service mindset. At school, that has meant leading MAKERs' Club, building campus web platforms, assembling network infrastructure, and working with teammates under messy real-world constraints.
