I'm just a simple man who likes writing, blogging, playing PC game, watching movie, and listening to music. I had an experience in teaching English in Jakarta and Bekasi (2008-2018). My books: Filateli Sebagai Hobi dan Investasi (Balai Pustaka, 2001), Kursus Singkat Bahasa Inggris (BIP, 2011), Kursus Singkat Percakapan Bahasa Inggris (BIP, 2013), Kursus Singkat Bahasa Inggris Bisnis (BIP, 2016), and Percakapan Inggris-Indonesia Bidang Perawat dan Rumah Sakit (BIP, 2021). I had a diploma in graphic design from a School of Design in Jakarta (1993), but later changed my interest into English and literacy. Sometimes I write my blog in English or Indonesian. I was born and live in Jakarta. No one is perfect. Stay humble.
