Skills
Some skills I developed through courses and my internship experiences.

I also learned data visualization and forecasting. I am familiar with the use of R Studio.

I am good at time management. All my internships were finished perfectly in my study terms. I managed the work and study well. I am skilled in prioritizing and completing assignments in timely manner, with accuracy and attention to detail.
