~/whoami
I build AI systems and the software around them. At ATASK I run a pipeline that turns educational material into practice questions. At Sydeco I lead product engineering on security platforms, including an AI behavioral firewall.
I graduated with a B.Eng in Informatics from Universitas Stikubank in October 2026. On the side I build web apps for clients, from a kids' wellbeing app to a retail point-of-sale system.
