Restaurant merchants needed one coherent app even when the underlying hardware, device SDKs, certification requirements, and behaviour changed from one terminal to the next.
This account stays at the product and system level to respect customer, employer, and platform confidentiality.
I led Android development across multiple terminal environments. Reusable device-integration and transaction modules gave the merchant application a consistent way to represent state while keeping the details of each device SDK isolated.
Device-integrated work involves more than invoking an SDK. The experience has to account for device behaviour, physical interaction, errors, recovery, operational support, and the certification expectations around secure transactions, including EMV-capable flows.
I delivered a tipping flow with clerk attribution so gratuity could be added during payment and associated with the person providing service. The feature required coordination across Android, backend, QA, and operations through rollout.
A more maintainable Android codebase that supported multiple terminal environments, compliance delivery work, and restaurant-specific features from one product surface.
