Summary
I’m a front-end developer who enjoys working on AI-related features, especially computer vision. I’ve worked with YOLO for object detection and integrated it into web and mobile applications to handle real-time data and visualization. I mainly work with ReactJS, React Native, JavaScript, and Java, and I want to move further into building AI-powered applications.
