Hello there,
Hope you are doing well!
My name is Deep Panchal, I am a full stack developer having 6+ years of experience and especially 2+ years of experience in React JS. I understand that you want to secure your idea that's why you are not sharing the information at this point. But without seeing your requirements its bit difficult to assist you. For that I would like to sign NDA (Non-disclosure agreement) with that your idea will be secure and I'm able to understand the complete requirement.
I would like to talk with you on this, Let me know your good time for a call.
Looking forward to working with you.
Kind Regards,
Deep
