I am an aspiring Data Analyst with a strong mathematics background and an interest in using data to support strategic decision-making. Seeking to apply my analytical mindset in a professional environment, I completed an Archivist Internship, where I organized and cataloged over 2,000 archives and developed an Excel dashboard that reduced administrative processing time by 40%. Building on this experience, I completed the ReVoU Full Stack Data Analytics program to strengthen my technical skills.

Through hands-on projects, I gained practical experience using SQL, Python, Microsoft Excel, Tableau, and Power BI for data cleaning, analysis, visualization, and dashboard development. I am eager to apply my technical knowledge and continue growing as a Data Analyst.
