Data Analyst transforming complex datasets into actionable insights and dashboards.
What I'm looking for
I’m a Data Analyst who turns large, messy datasets into clear decisions. I processed and organized datasets spanning more than 30 months with over 200,000 transactions, built interactive dashboards and visualizations with Looker Studio and Microsoft Excel, and used Python association rule mining to find frequent product pairings from customer data.
I also enjoy building learning experiences and supporting people through transitions. As a Student Buddy, I guided new TIAS students with coursework and campus resources while organizing activities to strengthen community, and I taught MySQL and JavaScript applications for practical, fundamentals-based technical skill development.
On the technical and research side, I’ve analyzed customer behavior using Excel dashboards, and I’ve supported regression teaching across 90+ students using SPSS, Minitab, and ArcView. My projects include a scalable Node.js news scraper for structured dataset exports and a Django digital platform prototype connecting local fashion SMEs with customers, plus research focused on optimizing GCN-BILSTM models for classification and forecasting.
