Creating new functionality based on the project specification, Development of a survey functionality, Adding new functionality to existing code, Working with change requests, Create custom functionality, Data migration, Deploy, Communicate with client , Manage code on front/back end Technical challenges: It all started as a small project for the client and his friends. And it was decided to do it on Firebase, as it would be faster and cheaper. But after 2 months, we decided to add a number of functions that were not included in the tasks before (chat, settings, notifications via mail and mobile phone, etc.). So, after analyzing all the requirements that had to be implemented, a decision was made to migratе on NestJS , as these are more rational technologies for this flow of tasks. Was engaged in a complete migration to new technologies and it gave a benefit in work productivity
