From December 2021 through October 2023, I worked with Timart as a contract Flutter engineer, collaborating with product, design, and engineering teammates on a mobile experience serving over 200 businesses at the time. The product needed to remain useful as network conditions changed.
Offline-first delivery
I implemented local storage and synchronization with SQL Entity so core product flows could continue offline and reconcile with the server when connectivity returned. GraphQL queries and mutations handled the application's data exchange.
Product operations
Firebase Cloud Messaging supported notifications, while Analytics and Crashlytics provided usage and reliability signals. Together, those tools made it easier to understand the product in the field and diagnose issues beyond the development environment.
The project strengthened my understanding of mobile reliability: intermittent connectivity is not an edge case when it is part of the user's everyday context.
