Hi! Hope you are well,
My first concern is DB, MySql is best, the last versions before 5.8 was slow and less secure but now 5.8 is much secure and faster that's why uber has been moved from nosql to mysql,
Secondly I am a experienced NodeJS developer, I will secure your API's by JSON Web Token, so that no one will come over it, also I will implement helmetJS to make it more secure from XSS attach, also we will user cloudflare to secure API's from DDos Attack.
I want rating, so right now I can do it getting fewer money to build up my profile. '
please give me a chance.
