Davidiw
Contributed to the aptos-labs/aptos-core and KeystoneHQ/keystone3-firmware repositories by building features and improving reliability across blockchain and embedded systems. Developed a Move-based dynamic dispatch engine example to enable flexible on-chain code invocation, decoupling dependency loading for improved runtime efficiency. Enhanced documentation quality and repository health by refining docstrings and updating tooling references, supporting maintainability and onboarding. Delivered Aptos blockchain support with USB signing in Keystone firmware, updating the GUI and image assets. Improved firmware build reliability by updating Rust toolchains in CMake, and strengthened security in aptos-core by disabling a risky account abstraction function and adding targeted tests.
