I want to make application like Zomato, #Foodpanda.

Which stack is best for this? As I have expertise in Java and Angular. What is the best stack you will recommend?

Web Micro-service / Mono? Angular / React? Amazon Web Services (AWS) / Google Cloud Platform? DB : SQL or No SQL

Mob Cross-platform: React Native / Flutter

Note: We are a team of 5. what languages do you recommend if I go with microservices?

Thanks
