Born in 1994 in Varaždin, I’m a senior frontend engineer with a strong focus on clean code, team collaboration, and building sustainable software. I started my academic path in mathematics, but discovered a passion for programming and shifted to the Faculty of Organization and Informatics, where I found the perfect fit between theory and practice.

During my first year of graduate studies, I began working at Emil Frey Digital as an iOS developer. As the company’s focus evolved, I transitioned to frontend development with Angular — a path I’ve followed ever since. I spent 3.5 years honing my skills there. Over the years, I’ve worked across several roles and companies: as a Product Owner at Porsche E-Bike Performance (formerly Greyp), as a Senior Angular Developer at Endava, and as a Teaching Assistant at the Faculty of Organization and Informatics (a role I continue to hold). In April 2024, I returned to Emil Frey Digital to apply my broad experience and lead key projects.

My core interests include writing clean, maintainable code, improving developer workflows, and helping teams grow through better communication and feedback. I believe that great code is built by great collaboration — and that learning to give and receive feedback well is one of the most valuable skills a developer can develop.

When I’m not coding, you’ll often find me behind a camera lens or building intricate LEGO sets — two hobbies that fuel my creativity and attention to detail.
