Mentor Profile

●Background before joining COCONE
After working in the SI industry as a part of a large scale mission-critical system for a government agency, he joined the game portal site HanGame as an early member because he originally liked games.
Han Game will launch a billing system to manage in-game currency.
In the second semester, he also experienced accounting work and built a linkage with the management accounting system along with accounting work. After that, he was introduced to Kokone and joined Kokone.

●Why I joined COCONE
My previous company had grown so large that I was doing a lot of routine work.
When my main focus was on management, I wanted to study at a small company again.
They are given almost all the rights to build the system and can create freely, which is fun and leads to skill improvement, but it is also a heavy responsibility.
However, the developers of Cocone are all very helpful and helpful people who will tell you immediately if you have any questions.
I was attracted by the homelike atmosphere.

●We Would like to work with people like this
Who can work responsibly by themselves
Who can absorb knowledge from members and give it to others.
