👩💻 I am transitioning into a career as a Data Analyst, with strong skills in data wrangling and data visualization.
🍴 With a background in hospitality, I gained hands-on experience analyzing sales data and KPIs that directly impacted business decisions. I tracked daily revenue trends, built Excel reports with pivot tables to monitor performance metrics, and identified insights that optimized workflows, reduced service times, and captured additional upselling opportunities. My work analyzing customer patterns and product performance to inform menu and pricing strategies showed me the power of data-driven decision making - sparking my passion for analytics.
📈 Currently advancing my Python and SQL skills through hands-on projects while building a portfolio that showcases my ability to transform complex datasets into clear, actionable, and visually engaging insights.
