## About Me

I am a data analyst transitioning from a strong Physics background into analytics, with practical training from the Big Blue Data Analytics Bootcamp. I focus on turning raw information into clear, actionable insights that support better business decisions.

I have hands-on experience working with high-volume, accuracy-critical operational data in reservations, invoicing, and financial reporting. In my recent roles, I managed transactional data, improved reporting accuracy, and helped streamline internal processes.

I am comfortable working with Python, SQL, Advanced Excel, Power BI, and Tableau. I also have experience with exploratory data analysis, dashboards, data cleaning, and statistical analysis.

My project work includes pricing analysis, Airbnb market analysis, and product analysis, where I used data to identify trends, evaluate business opportunities, and build interactive dashboards. These projects strengthened my ability to communicate insights clearly and support data-driven decision-making.

I bring a problem-solving mindset, attention to detail, and a strong ability to adapt to new tools and workflows. My background in Physics helps me approach complex problems logically and analytically.

I am now looking to grow as a Junior Data Analyst and apply my technical skills, analytical thinking, and business understanding to meaningful data challenges.
