I’m an aspiring Data Analyst with strong foundations in SQL, Python, and data analytics tools. I perform database queries, CRUD operations, data analysis, and dashboard development with Excel and Power BI, and I focus on data cleaning and exploratory data analysis to generate actionable insights. In my projects, I combine analytics with real-world problem solving—for example, Aurora AI, a smart assistance web application using YOLOv8 and OpenCV to detect objects and verbally describe them to visually impaired users with direction and estimated distance cues. I also build business-facing reporting and database-backed analysis. For Superstore Sales Analysis, I analyzed 9,994 retail orders with Python (pandas, matplotlib, seaborn) and delivered an interactive Power BI dashboard using DAX measures and dynamic slicers, while my Retail Database Analysis project emphasized normalized relational design with primary/foreign keys and complex SQL joins, aggregations, and subqueries.
