About Me

  • 👋🙂 Hi, I’m Charlene!
  • 👩‍💻📊 I’m a seasoned Marketing & Communications Strategist, now diving into the world of Data Analytics.
  • ⚖️🧠 I’m energized by the blend of creative thinking and data—where right-brain creativity meets left-brain logic is my sweet spot.
  • 🌱📚 Currently, I’m mastering data analytics by honing my expertise in Excel, SQL, R, Python, and Tableau, after completing the Google Data Analytics Certificate and working on the Meta Marketing Analytics Certificate.
  • 👀💡 I’m eager to contribute to projects that combine creative marketing with analytical insights.
  • 💞️✉️ If you’d like to collaborate or learn more about my work, please reach out at [email protected].
  • 🌍🍴 Fun fact: I’m a globetrotting foodie—I’ve visited 13 countries and counting, and my dream is to eat my way through every continent, one delicious dish at a time.
