I wanted to actively analyze product data, so I changed my job from data scientist to product analyst.
Data analysts who work alone have a wider range of work than you might think. I would like to share my thoughts on how to maximize efficiency with limited resources, such as how to easily check dashboards and indicator changes, and how to quickly process analysis requests.
Are you worried about whether a non-major can become a data analyst? Are you working as a data analyst but wondering if this is the right thing to do?
Get 200% honest, realistic advice from industry analysts!
I learned data analysis to find answers in a world where there are no right answers after starting a business. I worked as a data analyst and now I am working on growing services based on data.
I am a Samoyed-loving and curious data analyst. I enjoy the process of discovering hidden secrets through data. I enjoy communicating work and analysis results in an efficient way.
I have been working for 8 years already. Ironically, I have come to believe in the power of data more while working with Datalian members on various tasks such as marketing and service planning than when I was working only as a data analyst. I am interested in conveying data analysis in a way that anyone can easily understand.
I worked as a data analyst at the recruitment platform Jobplanet, and now I work as a content marketer and data analyst at Datalian. I am working to spread the word so that those who are curious about data analysis can easily and quickly access data analysis content that is close to practical use.
