My role and work

As a Senior iOS Engineer at KSF Technologies AG, I contributed to native iOS development within Sony Music's financial application ecosystem using Swift, UIKit, modular architecture, and reusable software components.

My broader engineering responsibilities included secure application infrastructure, authentication architecture, Core Data integration, Keychain abstractions, and interface-driven service design, supporting testability, maintainability, and consistent application behavior across modules.

Worked on engineering initiatives involving custom interactive financial data visualization, addressing limitations of existing third-party charting components and improving the presentation of financial metrics.

Contributed to the progressive integration of functionality across Sony Music applications, supporting the transition toward a unified Artist Portal experience and more maintainable shared infrastructure.
