About

I am currently a penultimate Bachelor of Data Science student with a keen interest in data analysis, machine learning and data engineering. I am exploring hands-on projects using tools like Pandas, NumPy, yfinance, LangChain, Hugging Face, PyPDF and Matplotlib to build foundational skills in data preprocessing, visualization, engineering and model development. I am eager to grow through practical experience and continuous learning.
