About

Professional summary

I am a Product Designer and Frontend Engineer with more than 17 years of experience across digital design and development. I have worked in fintech, automotive e-commerce, hospitality, travel, betting, energy, and enterprise software.

I translate complex business requirements into intuitive user journeys, scalable interfaces, responsive web experiences, and reusable design systems. My work spans UX/UI design, prototyping, user flows, visual design, and frontend implementation.

I bridge design and engineering by translating Figma designs into production-ready TypeScript, JavaScript, HTML, and CSS. I am experienced with component-based UI development, Blazor, C#, ASP.NET MVC, REST API integrations, and cross-browser frontend development.

I have designed enterprise dashboards, financial management workflows, e-commerce journeys, travel booking interfaces, hotel-service platforms, and live-betting products. I collaborate effectively with business analysts, stakeholders, backend engineers, and product teams.

I use AI tools including Claude and ChatGPT to explore designs, prototype interfaces, evaluate complex UI states, and support code generation. I am fluent in English and a native Serbian speaker based in Belgrade.
