What I'm looking for

I seek a data analyst role where I can apply Python and Power BI to turn messy data into clear insights, work on collaborative teams, and grow into advanced analytics responsibilities.

I am a detail-oriented data professional with 1.5 years of hands-on experience in data annotation and quality assurance, focused on improving AI model performance and maintaining 99%+ accuracy in large datasets.

I leverage Python (Pandas, NumPy), Power BI, Tableau, Excel and ETL best practices to clean, transform and visualize data, automate repetitive processes, and optimize workflows—achieving measured efficiency gains.

Through academic projects and professional work, I build interactive dashboards and data-driven insights that inform decisions, and I am passionate about transitioning fully into data analysis roles where I can expand my impact.
