# JobRambo



> Better naming conventions, better-layered architecture, separation of operations

> 



> Better security guidelines, json webtoken with live access authorization, http-only token, encrypted and https only cookie

> 



> Better database optimization split into atomic tables for limited works, enhanced indexation and validations
