Summary
As a Data Analyst with a background in medicine, I bring a unique perspective to analyzing and
interpreting data effectively. My experience includes utilizing Python for data manipulation and
analysis, with a strong grasp of libraries such as pandas, NumPy, and Matplotlib. I have worked
extensively with data from various sources, including CSV files and databases like SQLite3 and
PostgreSQL.
My skills in data cleaning and preprocessing, along with statistical analysis and visualization,
enable me to uncover valuable insights from complex datasets. Drawing from my medical
background, I apply a meticulous approach to data validation and accuracy, ensuring reliable
conclusions and actionable recommendations.
My focus as a Data Analyst is on optimizing data workflows, identifying patterns and trends, and
contributing to data-driven decision-making processes.
