Welcome!
My name is M. Thio Saputra - known online as Flessan. Here you'll find my adventures around the web, automation, open source, and the Geometry Dash community.
I'm a self-taught web developer & automation engineer from Banjarmasin, Indonesia. I build and deploy fast, scalable static and dynamic web applications, and I'm currently a student in the RPL (Software Engineering) program at SMKN 4 Banjarmasin.
My biggest adventure so far is GDIPS, the open-source, community-driven Geometry Dash Indonesia Private Server.
