About

Professional summary

I am a software designer and frontend developer based in Belgrade, Serbia, with extensive experience building web applications, enterprise software, e-commerce platforms, and digital products. I combine UI/UX design expertise with hands-on frontend development to create practical, user-centered interfaces.

I work with HTML5, CSS3, JavaScript, TypeScript, Blazor, C#, ASP.NET MVC, and modern frontend workflows. My background includes translating Figma designs into production-ready, responsive, cross-browser-compatible applications.

I have contributed to projects in energy, banking and leasing, automotive e-commerce, travel booking, live betting, hospitality, and media. I am experienced in designing complex workflows, reporting modules, search and filtering interfaces, payment-related screens, and high-volume transaction experiences.

I use Figma, Adobe XD, Photoshop, Git, Visual Studio, VS Code, WordPress, and Umbraco CMS in my work. I also leverage AI tools such as Claude, ChatGPT, and Gemini for AI-assisted development, prompt engineering, and accelerating design-to-code workflows.

I collaborate effectively with backend developers, product stakeholders, and cross-functional teams to define requirements, integrate RESTful APIs, and deliver polished digital experiences. I am focused on performance, usability, maintainability, and clear visual communication.
