Issue #1
I have attached an architecture design with the PR which should be self explanatory, do reach out if there is any question. Regarding the decision around tech stack for this project, the decision and reason for the tech is as following:
Backend
Nestjs
Reason: I have decided to go with Nestjs since it is an opinionated framework, that enforces alot of best practices and functionality out of the box
Frontend
Nextjs
Reason: React is a widely adopted framework of choice for frontend development in the community and at the time of writing, I have not had extensive experience working on other frameworks, therefore have decided to opt Reactjs.
Database
PostgreSQL
Reasone: Open sourced, mature RDBMS, though it would have been acceptable to use NoSQL database such as MongoDB as primary data store, there might be scenarios where high level of transactional gurantees are required in the future.
