Uroš Marković Recent IT Graduate | Full-Stack Software Engineer Node.js • PostgreSQL • Docker • React • TypeScript Serbia, Europe - About Me I am a recent Information Technologies graduate from the Faculty of Sciences, University of Novi Sad, with hands-on experience building and maintaining a complete production web platform from scratch. For the past 7 months, I have been developing "StreamAF", where I am responsible for the platform across the full engineering stack: frontend, backend, database, infrastructure, deployment, testing, security, integrations, analytics, and ongoing production support. I am comfortable taking a feature from an initial business requirement through architecture, implementation, testing, deployment, and maintenance rather than working only within one isolated part of a codebase. My strongest area today is modern web development with TypeScript, Node.js, React and PostgreSQL, supported by Docker-based infrastructure and automated testing. I also make extensive use of modern AI-assisted engineering workflows and prompt engineering for architecture exploration, implementation, debugging, refactoring, testing, documentation, and code review, while maintaining direct understanding and ownership of the systems being developed. My earlier background includes C#, C++, Unity, PHP, Python, algorithms, data structures, and competitive programming. - Professional Experience Full-Stack Software Engineer — StreamAF 2026 – Present Built and continue to develop a production web platform from the ground up.
