Summary
🤩
RockstarOndrej Mikle-barat is an architect, researcher, and developer with 15 years of experience building secure backend services, cryptographic systems, and security protocols. Based in Prague, he blends deep cryptography and privacy expertise with hands-on embedded and IoT engineering, notably contributing to the well-known Trezor firmware by porting core firmware to the T1 device and adding runtime debugging hooks. He has a knack for low-level debugging—“debugging the debugger’s debugger,” including silicon-level issues—which informs pragmatic, audit-ready designs. Ondrej consistently bridges research and production, delivering robust, performant security primitives and firmware improvements that scale from protocol design to device startup and storage.
