MCA final year — need a real-world-scale AI project idea, not a toy/tutorial-level one[D]

I'm an MCA student with hands-on experience in Python, LangChain, Chroma, HuggingFace, and FastAPI (built a RAG document-QA system already). My project guide specifically wants a real-world problem — something an actual company would need solved — not a generic "sentiment analysis on tweets" or "spam classifier" type project that's been done a thousand times. Looking for: - A problem real companies (IBM, Google, etc.) actually publish as challenges — not something I invented - Enough depth that I can defend it under tough viva questioning - Realistic for one person to build in a few months, but NOT trivial What's a project you've seen (or built) that actually impressed a project committee or a recruiter? What made it stand out over the usual final-year submissions?
