I’m Nebojša Trivunović, a software engineer and full-stack developer from Brod, Bosnia and Herzegovina. I enjoy building reliable web and mobile applications and turning ideas into working features—whether that’s designing APIs, integrating external services, or improving performance. I’ve worked across the stack with technologies like Node.js, Express, React, React Native, MongoDB, PostgreSQL, and .NET, and I also gained hands-on QA experience through manual testing and structured bug reporting. I’m especially interested in practical systems work—auth and payments/OAuth flows, AI-based content moderation, and scalable backend development for real users.…I’m Nebojša Trivunović, a software engineer and full-stack developer from Brod, Bosnia and Herzegovina.
