I worked on a few iterations of this app as the lead developer. We transitioned through various design iterations, and I personally took ownership of creating an isolated package for the business logic components that eventually went on to help us quickly develop a desktop version of the app.

​

Websocket events were used primarily for the real-time event monitoring and dispatching, and we created a feature-rich chat experience together with tools to engage with people in your organisation and manage files.

​

I personally developed features including:

• data structures and event queues to ensure correct message orders and restoring proper state after losing connection

• message draft states which were restored on entering channels and synced across devices

• integrations with various third-party APIs to build support for features such as GIF insertion

• custom-built components such as swiping/dismissable list items and list views when base Flutter components were inadequate
