Built Chronos, an interactive timeline application for visualizing historical events. Users can create custom timelines, add events with dates, categories (tags), and descriptions, and view them on an interactive horizontal timeline with clickable markers. Designed the interface with a clean, editorial aesthetic and implemented features including an event editor, category tagging system, and a public view mode for sharing completed timelines.

Retail Sales Analysis by Season and Category
I analyzed a retail sales dataset to explore how total sales vary across seasons (Fall, Winter, Spring, Summer) within three product categories: Beauty, Clothing, and Electronics. Using Python (pandas and matplotlib), I aggregated total sales amounts and visualized the results in a grouped bar chart to compare seasonal performance side by side.
Key insight: Winter consistently drove the highest sales across all three categories, while Spring showed the weakest performance in Clothing and Electronics — suggesting a potential opportunity for targeted spring promotions.

Built with a shared visual identity (gold/silver palette, serif + sans typography), an interactive company carousel, contact forms, and a GDPR-compliant whistleblowing channel.
