Archaeologist turned engineer.
“Not everything that's engaging is useful. I try to build things that are.”
I studied archaeology at the University of Belgrade, a BA with honours and then an MA, trained at the National Museum in Belgrade and earned a Professional Curator Certificate. At the Belgrade City Museum I led the photogrammetry for Singidunum 3D, turning Roman artifacts into 3D models anyone can explore.
English came early: I finished intermediate school in New York in 2007. Later I taught English as a second language and translated between English and Serbian.
Since 2021 I've shipped production software: first as a core engineer at ALL.ART behind SolSea, now in my own companies, end to end, from product and design to AI pipelines, payments and the servers they run on. I'm a member of Superteam Balkan.

✦ From the museum
Singidunum 3D
Roman Belgrade was called Singidunum. With the Belgrade City Museum I photographed its artifacts and rebuilt them in 3D, so anyone can turn them over in a browser. The project was featured in European Heritage Days.
Reconstruction of a Roman household shrine. My reconstruction of a lararium, with three bronze figurines of the Lares, the spirits that protected a Roman family and its hearth.
