About Mario
Full-Stack Engineer and Tech Lead at KONČAR
where I build software used by electrical engineers to run transformer and high-voltage equipment tests. Think calculation tools, automated PDF test reports, and internal systems connected to physical testing hardware.
I work independently, communicate well, and I'm used to software where mistakes actually matter.
