Work Values

Customer-driven

Users who use System & Software are the proiority for the system design and development.

[ex] After completing development of the intranet system at KIST, I was chosen by customers as the only maintenance member thanks to the convenient system which I was designed and developed.


Think further

Think beyond the needs for extendability & integration

[ex] When building a messaging automation system, I designed and developed considering extendability so that I could respond to additional demands of customers flexibly afterward.


On time

Keep schedules through proper and efficient planning

[ex] Most of the projects I had, were delivered and performed on time.


Reliability

Users can use a system/software stably and peacefuly

[ex] When working at Samsung, I completed my developments without any error so that I could get extra education(about Component Based Design) during debuging periods.
