Summary
Dear Hiring Team,
My name is JeongSang Choi, and I am excited to apply for the Cloud Support Associate position at AWS. I am passionate about solving customer issues with technology and eager to grow in a role that values both technical skills and communication.
While working at Coupang, I was responsible for reviewing and verifying data accuracy, contacting vendors for clarification, and using Python and Excel for basic automation tasks. Although I would not consider myself an expert in cloud technologies yet, I bring a strong willingness to learn and a proactive mindset. I take pride in being dependable and detail-oriented, especially when working in team-based environments.
I believe this opportunity at AWS will not only allow me to develop my skills further, but also let me contribute meaningfully to the team by providing reliable and customer-focused support.
Thank you for considering my application. I look forward to the possibility of growing together with AWS.
Sincerely,
JeongSang Choi
