Q:What is your leadership style?
I have a deep appreciation for people, relishing in their growth. I find fulfillment in coaching and mentoring, and I would describe my leadership style as enlightened.
I also value simplicity and actively strive to follow the KISS (Keep It Simple, Stupid) principles, particularly in the technology domain. I've observed numerous instances of over-engineered systems that ultimately lead to failure.
I am a pragmatic and down-to-earth individual with high standards, particularly when it comes to serving customers. -
