CSV Cleanup & Missing Value Review
Sample demonstration project showing how I clean and review CSV data with missing, incomplete, or inconsistent values. I organized the dataset, corrected safe formatting issues, identified missing fields, and flagged uncertain records for manual review instead of guessing or overwriting source data. The original file was preserved and all changes were made on a separate working copy to maintain traceability and data integrity.

Checkout Research: Why Customers Abandon Cart, and What It Takes to Keep Them
Officeworks' desktop checkout converted above industry standard, but mobile conversion lagged and checkout took over 4x longer than the 1-minute benchmark customers expect. I led a mixed-methods research programme, an audit spanning 6 methods, 613 NPS responses, and 10 user interviews, to find out why.
The research surfaced three connected stories: customers need to feel confident before they can be efficient, cart abandonment has specific and fixable causes (hidden charges, security doubts, and slow load times ranked highest), and Officeworks' mobile checkout was underperforming its own desktop experience.
I translated these findings into 6 prioritized recommendations, including surfacing total cost upfront, making the mini cart editable, and redesigning for adaptive mobile checkout, directly shaping the roadmap for Officeworks' checkout redesign.
Organized, cleaned, and accurately formatted raw client database into Google Sheets with 100% accuracy. Applied color-coded status tracking (Verified/Pending) and standardized contact details for seamless workflow management.
