Partnered with university departments to execute end-to-end data processing, analytics, and visualization workflows. The primary objective was to transform messy, unorganized raw datasets—often plagued by missing values, misaligned structures, and inconsistencies—into clean, reliable data assets. By bridging raw technical data with intuitive visual design, I enabled decision-makers to quickly extract meaningful insights without getting bogged down by raw complexity. Technical Execution & Workflow Data Cleaning & Wrangling: Leveraged Python (Pandas, NumPy) and advanced Excel functions to inspect, clean, and standardize large raw datasets. Implemented automated scripts to handle duplicate entries, resolve formatting inconsistencies, and fill or filter missing parameters. Data Restructuring & Quality Control: Standardized column formats, normalized string inputs, and built validation checks to ensure high data integrity and accuracy prior to downstream analysis. Visual Storytelling & Dashboards: Transformed cleaned metrics into interactive dashboard displays and visual charts using Python (Matplotlib, Seaborn) and Excel dynamic charts, highlighting key performance indicators and subtle trends for non-technical stakeholders.
