A Hackathon developer participates in a collaborative programming event, often lasting several days, where they create, innovate, and solve problems. They usually work in teams, brainstorming software solutions or building prototypes for specific themes or issues. This involves intense coding, designing, and testing to produce a working model within a limited timeframe. They commonly use their skills in web development, data analysis, machine learning, and more. At the end, they present their project to judges. Apart from coding, they also learn new technologies, network with professionals, and often gain recognition or prizes for their innovative solutions.
