"One of the people who seems consistent and focused on what he's doing"
Not many gimmicks, doesn't seek the spotlight, but seems serious when discussing something.
From the interactions, he's the type who thinks before speaking.
His opinions are usually well-structured and not just throwing out random opinions.
If there's a discussion, he prefers to add a perspective rather than have a long debate.
Outside of that, he's also quite open and easy to talk to.
Can have a relaxed discussion, or discuss something a bit technical without making the atmosphere stiff.
In my opinion, the presence of someone like this makes the environment more balanced.
Not noisy, but the contribution is there and felt.
