Give me honest advice and recommendations
I'm a comp eng student and this is just a side project idc about commercializing this even though multiple people probably have something similar already. I built the frontend with HTML/CSS/JavaScript and deployed it on Vercel. The backend uses C# (ASP.NET Core) plus REST API routes for deck analysis and card data. I also integrated a Python-based ML service (FastAPI + scikit-learn) to predict win-rate trends and recommend high-impact card swaps, with PostgreSQL used for ML feedback/training data. I'm honestly building this to gain knowledge on API / ML fundamentals, etc. What are some things I could improve on or features that you'd like to see?
