I build generative AI features at NetSuite in Java and Python. Outside work I make small, fast tools that do one job well.

About

From research to production AI

I studied information technology and artificial intelligence at Brno University of Technology, with an exchange semester in Denmark and a machine learning internship in Barcelona. Today I work on AI in NetSuite's ERP platform. In my free time I build side projects and go to the mountains.
