About

Jehian Athaya

Engineering
with intention.

I'm Jehian a final-year Informatics student at Universitas Jenderal Soedirman with a deep interest in building things that work, and work well. My path has taken me from designing hospital kiosk systems on tight deadlines, to engineering ML pipelines for national-scale food security planning at the Ministry of Agriculture.

What drives me isn't the stack it's the problem. I'm drawn to the intersection of data and interfaces: systems where clean architecture in the back translates to real clarity for people in the front. I care about documentation, about teaching others, and about the kind of code that doesn't break at 2am.

Outside of work, I'm a workshop instructor, an open-source contributor, and someone who genuinely enjoys sitting with village elders in Banjarnegara to digitize historical manuscripts because technology is only interesting when it has a human story behind it.
