(01) — About
I started in tech in 2018 and neverstayed in one lane — games, startups,automation, then companies of my own.
Now I'm majoring in Information Systems while running Kasankaf — a system architecture practice, and the parent of Skybooth and Omnikaf. The throughline across all of it is the same: understand the business problem first, then build the smallest system that genuinely solves it.
