PROFILE
Computer Science student with practical experience in SQL, relational database management,
Metabase, and Power BI. Worked in database support, handling technical requests through
Service Desk, and later as a Data Analyst, where I wrote complex SQL queries, built dashboards
in Metabase, and prepared reports in Excel and Google Sheets. I’m eager to bring my practical
technical background and strong problem-solving skills to a data-focused role.
