Projects

general concepts

• Role Based Access Control(RBAC):
  • Once we login an account, we have different roles, different roles will see different contents.
  • whether we are admin or external user, internal user.
  • if we are external user, we have different vip levels or different discount, and so on.

core

• describe it within a minute(3-5 sentences, 30 secs)

  • define industry, it need to be a part of business need to be a web app
  • internal use or external use or hybrid

• tech stack details

  • spring/springBoot/java/versions/database/frontend frameworks/…
  • pros & cons

• distributed? / frontend/ backend(java 8/11/13)/ database/ internal components(jdbc/ hibernate/ spring data jpa)/ how you implemented microservices(spring cloud or kubernetes)

• data: frontend data/ what kind of payload/ what kind of format/ design dataflow: FE->BE->DB/ then we have architecture/ then in middle we should add buffering or caching(just add different tools to handle different problem, i.e. failure tolerance, scalability, ….)

• on-premise or on cloud(which cloud is used)

• people we worked with

  • Agile style/how big the team/what’s my role/different scenario we need to talk to different people
