What I'm looking for

I seek a data-focused role using SQL, Python and BI tools to build dashboards, drive insights, and grow technically in collaborative teams.

I am a self-taught data analyst with hands-on experience across finance, healthcare, and retail, specializing in cleaning, analyzing, and visualizing complex datasets.

I have built interactive dashboards in Power BI and Tableau and written optimized SQL queries to extract and transform cloud-based data, improving reporting efficiency for clients by over 40%.

My project work spans COVID-19 analysis, global layoffs cleansing, job satisfaction dashboards, and machine learning classification models using Python, with clear visualizations using Seaborn and Matplotlib.

I continuously expand my skills through structured online programs and practical projects, bringing analytical thinking, problem solving, and strong communication to collaborative, remote teams.
