What projects can I build around capstone during an MCA?

A strong MCA project should solve a clear problem and demonstrate real technical work. A student can strengthen it with proper documentation, testing, source control and a working demonstration. If your target role involves capstone, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the capstone aspect of MCA study. For this specific question about capstone, the practical takeaway is to relate the concept to your own MCA learning goal.
