Note: Non-commercial personal learning project. Built purely for educational and experimental purposes.

About Me

Hi! I'm Arjun Prabhulal, a Principal Engineer in the Retail Industry, Google Cloud Certified Cloud Architect, ML Engineer, and Data Engineer passionate about AI/ML and Open Source. NoteCore AI is my non-commercial personal learning project to experiment with AI technologies, Vibe coding, and Engineering with LLM.

This is NOT a business or commercial service. It's purely for educational purposes - my way of learning full-stack development with modern AI models. I'm constantly experimenting with new features and improvements. Since I'm paying for the infrastructure out of pocket, there are reasonable limits to keep things sustainable.

Your feedback helps me learn and improve. If you find bugs or have suggestions, feel free to reach out!
