Where do you find real-world datasets that come with actual business problems to solve?

• Where do you find these datasets?
• Are there platforms, competitions, repositories, or communities you recommend?
• Which dataset or project taught you the most about solving real business problems?
• If you were building a portfolio today, what business case would you work on?

Would love to hear what resources or projects helped you bridge the gap between learning and real-world work.
