Networking tips for Computer Science students?

I understand that networking is crucial for career success in Computer Science, but I'm not sure how to build professional connections effectively. As an introverted person, I find networking events intimidating and don't know how to approach professionals in my field. I've attended a few career fairs and industry events, but I often feel awkward starting conversations or following up with contacts. I'm also unsure about how to maintain relationships and provide value to my network. What networking strategies have worked best for you? How do you approach professionals at events, maintain relationships over time, and leverage your network for opportunities? Any advice for introverts or specific platforms that work well for Computer Science professionals? I'm currently studying at University of Lagos and would appreciate any advice from fellow students or graduates who have been in similar situations.
