About Me

DATA & ANALYTICS
I am an entry-level Data Analyst with a Computer Science background and hands-on
practice in Excel, SQL, Python and statistics. I enjoy turning data into clear conclusions: Excel
analyzing metrics, finding patterns and explaining what happened and why.

SQL
I am looking for my first role in data analytics, where I can work with real data and large
volumes of information and learn from experienced analysts. I have completed data science
Python (pandas, Matplotlib)
courses and keep practicing on hands-on tasks.
