    I always knew that I wanted to write, but I wasn’t ever sure how to go about it. I started a small personal tech blog when I was around 15 and when I joined college, I wrote for Poin Asia (WinPoin - #1 Windows Portal Indonesia). These experience made me more interested in developing a software, so that I had the opportunity to study with the experts at Binar Academy. When I graduated from Binar Academy, I joined the Software House Agency (Kreasi Kode) as an Android Developer. I worked on 3 projects from their clients for 3 months. A few months later, I received an offer to become an IT Project Manager at a new Startup Digital Travel Agency (Travling) which I took as another big step for me to build a product from scratch. For 1 year and 6 months I led the IT team, we brought 1000+ downloads of our Android application since its first release and already have 2 regions that cover more than 500+ tourist destinations. After I felt that the development was stable and focused, I decided to finish my bachelor's degree in 2019 with a cum laude predicate. There are still a lot of things I want to implement, but I wisely decided to leave it and come back to explore many more things about technology and build a product. And my choice was anchored in an IT company in Jakarta, namely MII (Mitra Integrasi Informatika) as Application Development. I was assigned to a well-known bank in Indonesia, namely BRI (Bank Rakyat Indonesia) in a BRILink team as a Technical Writer. The experience here is truly extraordinary, as long as I joined the team it turned out that I was in the first position with the position of Technical Writer. For that reason, I was given the main responsibility for various documentation, both technical and non-technical, which means that I really learned a lot from A-Z about product knowledge. And now. To advance development to the next level, I joined the development team as an Android Developer. Responsible for the development of the BRILink Mobile application and Android EDC Device which we call BRILink MPOS. Outside of work, I create entertainment projects and content by applying my Digital Marketing knowledge to various social media platforms be it TikTok & Instagram.
