Hello Sir, First of all Happy New Year
Hope you are doing well,
I have read your post and got to know that you need to build a Slack app.
I know the concept of Slack and I'm using Slack from last several years so know all the features and functionality of Slack.
Let me tell you something about slack:-
Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business
We can use Slack to
-> Communicate with your team and organize your conversations by topics, projects, or anything else that matters to your work
-> Message or call any person or group within your team
-> Share and edit documents and collaborate with the right people all in Slack
-> Integrate into your workflow, the tools and services you already use including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk, and more
-> Customize your notifications so you stay focused on what matters
There are several other functionalities on slack,
Will explain you in detail via chat.
I'm pleased to inform you that I have a team of experienced developer in each skills of technologies and will happy to build Project Management App like Slack as per your need.
One more thing, need to know 'JSON dump of all messages' in detail & you want app in both android and iOS?.
