The problem DEV ARMY solves

Have a great idea in mind, are excited in the beginning, start working on it, and then the graph goes on tending to zero. This trend shows a reasonable rate of creativity but a depleting rate of implementation. I have worked on several projects, the ones having the potential to become the next big startup, but they go in vain because sometimes a particular tech stack is not known, or you have made too many commitments that you forget the exciting ones.
Also, after talking to people at our institution, people tend to complete things they have taken up when they have a partner whom they are accountable to. In these situations full of problems, what developers require is a platform for themselves, not just some random WhatsApp and Telegram groups, which are muted as time passes! The platform DevArmy aims to bring a platform for the developers to solve their problems.
What we call the members of the community is the "Soldiers."
Soldiers seeking solutions use the language of #hashtags

Challenges we ran into

Even today, when many developers are using flutter, the BLoC logic Documentations and practical implementations are not present. Fewer tutorials are present on working with Django REST Api and flutter, which makes our work less efficient. Even the existing university pattern of education does not give proper guidance about modern technologies.
Our Team tried leveraging the power of elastic search for the hack, but again, lack of Documentation was a significant issue.
