ABOUT ME

Profile Photo

Hello.

I’m someone who discovers people’s needs, creates solutions to meet them, and finds fulfillment in that process.

For me, achievement is not about grand titles or results, but the confidence that what I’ve created brings value to someone.

That’s why I enjoy solving problems and creating new things — because through that process, I continue to grow.
