Recently, during collaborations with the wallet team, I have interacted with many professionals, including members of the wallet security department. Their way of working left a deep impression on me—highly professional, always prioritizing user safety.

Among them, two technical leads stood out in my memory. I have had indirect cooperation with one of them, and direct project coordination experience with the other.

Regarding their characteristics, first of all, they have a solid technical foundation. Whether it’s server security architecture or supply chain security checks, it’s clear they put a lot of effort into their work—meticulous and thorough. Secondly, their work attitude is quite stable, and during communication, they speak in a gentle and friendly tone, making the entire interaction very comfortable.

But there’s also an interesting aspect: their obsession with technical details sometimes exceeds the norm. They delve deeply into the technical implementation plans of project teams and insist on manually verifying each one. This level of rigor clearly surpasses common review standards. Perhaps this is the professional trait of security experts—when it comes to ensuring user asset safety, there’s no such thing as “good enough.”
