About me
Background
I'm originally from Travnik, wrapping up my bachelor's in Computer Science at the Faculty of Mechanical Engineering, Computing and Electrical Engineering at University of Mostar. For the past 10 months I've been a software engineering intern at Deltico d.o.o. in Vitez, now transitioning to full-time - working on internal tools and client-facing web apps.
Before Deltico, I ran my own ecommerce business called EuroGuard, designing and selling 3D printed products. I handled everything - production, sales, IT, and built custom software to automate parts of the process. Running a business end-to-end taught me more about shipping real products than any course ever did.
During my studies, I've received several academic scholarships and taken part in hackathons, where I enjoyed the challenge of turning an idea into something people can try in a short amount of time. I got into tech as a teenager hosting and scripting game servers, and that curiosity gradually became a passion for building software that is useful beyond the screen. I still enjoy the same mix of logic, creativity, and figuring things out as I go.
