Rockstar🎓
Top SchoolVictor Chang is a software engineer with 11 years of experience building system-level and Android software, currently based in San Jose. He has deep expertise in low-level systems work—modifying Android's dynamic linker, contributing to ICU numerical formatting, and implementing a clean-room EXT4 filesystem in Rust at Google to enable cross-OS OTA updates. Victor pairs this with practical product-facing work on Android apps and device policy tooling, improving Settings, Contacts, and Test DPC behaviors and provisioning flows. He has a track record of shipping tooling and infrastructure, from driver qualification portals and test frameworks for Fuchsia to APK analysis services that informed platform compatibility decisions. Comfortable across C/C++, Java, Rust, Python and web stacks, he combines careful code maintenance with pragmatic fixes that surface in major open-source repos within AOSP and ICU. An engineer who moves between kernel-adjacent plumbing and user-facing features, he often uncovers subtle compatibility issues that unlock larger system upgrades.

Test DPC is a sample device policy controller for use with Android Enterprise. It gives developers the ability to see how their app will behave in a managed context such as device owner or within a managed profile. Users can set up a work profile, enable work apps, set applications restrictions, manage security polices, and much more. The app also serves as a implementation reference for other DPCs
