Years of practical experience as a Data Analyst with Bachelor's in Information Technology and my strong background in Data Analytics and Data Science, I believe I would be a perfect fit for this role. During my career, I have been entrusted with defining requirements, gathering and analyzing data, interpreting results, and recommending solutions. I have honed my skills in SQL(Advanced) writing complex and optimized queries, PySpark, Alteryx and Python for data analysis, data extraction, data cleaning, data transformations, and derive actionable insights. Performed data cleaning and feature selection using Pandas/PySpark and machine learning techniques to optimize model performance and improve data quality for analysis. Moreover, in creating reports and dashboards, I have utilized data visualization tools such as Power BI/Tableau, Looker Studio, Matplotlib/Seaborn, Plotly.
Worked with PySpark specifically for large datasets, extracting data from various sources, partitioning data, applying transformations using in-built or UDFs, and writing transformed data to various destinations, and optimizing performance of ETL pipelines.
