I’m Danilo Vrancic, a full-stack software engineer who enjoys building reliable web and mobile products end to end—turning requirements and Figma designs into clean UI/UX and production-ready backend services. I work with modern stacks like React, React Native, Node.js, and Spring Boot, and I focus on scalability, maintainability, and smooth user experiences. I also bring strong cloud and automation experience, including AWS-based deployments, REST API development, caching and performance optimization (Redis/Valkey), and workflow automation with tools like Make.com and n8n. Beyond coding, I’m comfortable collaborating with stakeholders across the full development lifecycle—requirements, implementation, testing, deployment, troubleshooting, and ongoing support—while leveraging AI-assisted development tools to move faster without compromising code quality.…I’m Danilo Vrancic, a full-stack software engineer who enjoys building reliable web and mobile products end to end—turning requirements and Figma designs into clean UI/UX and production-ready backend services.
