Data Analyst / Data & Technology Projects

January 1, 2024 - Present

Cleaned and structured datasets; performed exploratory data analysis to identify patterns, relationships, anomalies, and potential issues. Applied descriptive statistics, correlation, hypothesis testing (Chi-square), and regression techniques including OLS with evaluation metrics such as RMSE and MSE. Built analytical reports and dashboards using Matplotlib and related tooling. Developed machine-learning workflows for tasks including fraud detection, recommendation systems, and analytics for business/sales use cases. Investigated and monitored data/model drift using metrics such as PSI and KL divergence, and used data quality checks (e.g., validation/consistency). Worked with SQL and PostgreSQL for querying and data manipulation, and explored scalable processing with PySpark, MapReduce, and data engineering tools such as Kafka and Airflow. Produced documented findings and quality-checked outputs.
