@yavorivanov

Mobile software developer at DSK Bank, leading a design system integration and migration from Android Views to Compose.

At DSK Bank, I’m part of the platform mobile team, supporting other mobile squads with development tools and performance monitoring. I integrated SonarQube and JaCoCo, implemented features including session management and security monitoring, and led the design system integration and migration from the view system to Compose.

Previously, I worked as a contractor with design agencies, startups, and large corporations, often on greenfield projects or legacy codebases. Across Android and Flutter projects, I contributed to architecture, features, testing, and releases, including porting United Bulgarian Bank’s app to Huawei Mobile Services and improving accessibility for Sky Q.
