🖥️ about me

$ cat about_me.txt

I'm Cẩm Loan (Harley) - a Data Analyst at an app-based driver service platform in Vietnam. I dig into 500K+ trips and 400K+ users to find where customers drop off, why they don't come back, and which campaigns actually pay off. I build dashboards, design CRM & voucher programs, and automate reporting so the team can move faster. Currently open to Data Analyst roles in Marketing, CRM and Customer Analytics.
