* Developed an SDK that encapsulated the UI and logic for the user's medical history. I

Reactive Programming to our app, together with Kotlin Flows and Stateflow.

* Designed, developed, and delivered a ready-to-use application for one of my clients, which
helped him manage his cattle farm.
* Added a new feature that reduced the calculation times by displaying a calendar with
tasks to be completed in the current day. Those tasks were automatically calculated based
on the previously added entries in the app: newborns and other features.
* Expanded the app by replacing the local database with a remote database, thus increasing
the capabilities of the farm employees to work together on the same data at the same
time.
