Hi, I’m Christine – a full-time traveler and career woman. Although I’m from the Philippines, my location independent career took me to over 60 countries for the past 12 years. I also lived in 4 continents – from the Caribbean, South East Asia, Africa and now in Europe. But despite living in several countries, my love for Ireland remains the same. A country that had been a part of my life since I was 14 because of my love for Irish music and bands.
