About

I split my time between building information systems and helping students understand how software actually works.

Over more than 13 years I've worked as a programmer analyst and developer — at PT Petrolab Services and IPB University — building web-based information systems with PHP, JavaScript, and related tooling. I hold a Magister Komputer (M.Kom.) from IPB University.

Since 2022 I've been a lecturer at Universitas Sam Ratulangi in Manado, where I teach and supervise student research across information systems, decision-support methods, machine learning, and IoT. To date I've authored 21 publications.
