Hi, I’m Quy—an Applied Data Scientist. I’m from Hanoi, Vietnam 🇻🇳. Currently living in Singapore 🇸🇬.

I love building products that help people make better decisions.

My projects:

• Calens: a Chrome extension for Google Calendar Analytics.
• qrec: Open-source Project for Claude Code history management
• RecSys End-to-End Implementation Series

I used to teach a RecSys course for practitioners at FullStackDataScience.
