Mohammad Afdhal Jauhari, S.Kom.

I am a trainer in IT since 2014 and certified under CCNA™ and Cisco® Certified CyberOps Associate programs. I work at an IT company as a training and certification manager since 2015. 


I am a trainer in IT. I help others to master computer network concepts from basic to expert and make sure they have a good understanding. More than that, I am also trusted to lead the IT training and certification division at PT NetSolution to supervise the achievement of the company’s quality objectives in selling training and certification services to achieve the target. In addition, I have also helped many others to find jobs that match their expertise through a partnership program with a company providing IT human resources.


It is my passion since I was in high school. With more than five years of teaching experience in IT, it makes me more confident to say that I am indeed an expert in this.


As with teaching, leading has become my destiny. And it has been going on for almost five years. It will be an extraordinary experience at the same time tense for me.


When you find yourself worthy of getting a great job. It is there that I will bring you together with a job that matches your expertise and passion. Don’t worry, it’s free.
