What I'm looking for

I am looking for a role that challenges my technical skills and offers opportunities for growth in a collaborative environment.

I am a dedicated network engineer with over 14 years of experience in the field, specializing in network operations and technical support. My journey began with a Bachelor's degree in Electric Business from Changchun University of Finance and Economics, where I honed my leadership skills as Deputy Minister of the Student Union Sports Department and President of the Football Association.

Throughout my career, I have successfully led various projects, including a Private 5G initiative at SK shieldus Co., Ltd, where I developed comprehensive plans and coordinated cross-functional teams to enhance production security. My role as a Cisco TAC Engineer at Dalian Software Park allowed me to provide exceptional technical support to Korean customers, managing complex network issues and training junior engineers. I am passionate about continuous learning and staying updated with the latest technologies in networking and data centers.
