Dear Sir/Madam,

I was pleased to see this project open for volunteer and excited to submit my profile for consideration. Given my qualifications as a certified data analyst with both business and data science degrees, plus my experience in data management, I believe I am the right person to help our organization.

My interest is specifically in data analytics and management, which stems from my 2 years of experience as a data analyst for Tesco Corporation. I was responsible for analyzing shopping mall sales data with Excel, maintaining databases with MySQL management systems, generating BI reports and helping make business decision with the department and Board of Directors. I collaborated on solutions with different departments to meet Tesco budgets and increase customer satisfaction.

To extend my interest in data science, I have kept working on big data projects and certifications. I am proficient in data transformation and data visualization with BI reports by using Excel Power Pivot and Microsoft Power BI. Also skilled in cleaning data and building predictive models with Python, Pandas, Sklearn and Matplotlib by using Jupyter Notebook. Likewise, I am experienced in operating SQL server and Azure data studio.

Furthermore, the projects I listed on GitHub to demonstrate my recent data analysis experience, which cover data ETL, visualization, statistics, machine learning and programming skills. I welcome you to visit my website at https://github.com/jjiaoyan

Thank you for considering my candidacy for this job and hope to hear from you soon.

Sincerely,

Michelle Vanness
