Communication
Not a hacker, but a geeker, in my programming field.
I'm not a stereotypical "bookworm" lacking in communication skills, nor am I an exceptionally eloquent speaker.
I value and balance the effective expression in my professional terminology with other teams (non-tech teams).

Challenges
I seize the opportunity to showcase my fresh ideas or project concepts in the company-wide innovative project activities and Tech-Days.
In the photo on the right, I initiated and presented my avant-garde web3 initiative, underpinned by Ethereum blockchain infrastructure, aligned with the company's prospective strategic blueprint.

Work and Rest
Learn to work wisely, learn to rest efficaciously.
Cannot find the bugs in the app/program or tired of debugging? We need to relax and go for a walk; the train of thought will come to you.
