I can divide my working life into two parts; in the first IT-related part, I was a Navy Officer and teacher, in the second part I attended the pure IT world. In the first part, I achieved teamwork, leadership, management, problem-solving skills as well as continuous learning and teaching ability. In the second part, I learned Agile, AWS, DevOps tools, and Python. I'm currently mentoring so many teammates in the Clarusway IT School.
