  • Name: Denis Yordan Panggabean, S.Kom.

Besides that, I love metal music 🤘 to accompany me on daily routine. Also sometimes when I'm get bored, ussualy take a time to chill out in nature also playing a game as part of my stress management. As you can see some of my photos, this is me that love classic and some rock style. But don't worry I'm not rude or ignorant as I seem and definitly won't bite 😆. Actualy I'am a friendly, good attitude, and polite person, I ensure you won't regret to know me. 😊
