Worked on the google/android-cuttlefish repository to deliver integration of the jcardsim hardware simulator for Strongbox testing. Developed a new enable_jcard_simulator flag, wiring it through APEX configuration and ensuring the flag’s value was passed to the secure_env binary. This approach allowed the system to configure and communicate with the jcardsim simulator, enabling automated test cycles without reliance on physical hardware. Focused on configuration management and embedded systems, the work was implemented in C++ and system programming contexts. The result established an end-to-end testing pathway, streamlining Strongbox validation and improving the efficiency of hardware simulator-based test environments.
