An Dao / Embedded systems engineer
5 years in Tier 1 automotive: embedded software, vehicle diagnostics, and automated verification for safety-critical controllers.
Embedded-systems engineer in Stuttgart. Five years of Tier 1 automotive verification and validation for functional-safety systems: requirements, automated xIL tests, diagnostics, reviewable evidence. Eight pull requests merged in Eclipse OpenBSW.
Lab identity
Taktflow Systems is my public engineering lab—not a separate company or team. It is where I make the systems, tools, and evidence behind my work reviewable.
Engineering mindset
I enjoy turning complicated embedded behaviour into something teams can see, challenge, and trust.

System / vehicle
Virtual and physical controllers exchange CAN, diagnostics, and injected faults.
I designed the interfaces, integrated the firmware, and automated the verification evidence.
System / battery
Real foxBMS logic runs on Linux and SocketCAN—without live cells.
I ported BMS logic into repeatable Linux fault tests.
Tool / diagnostics
A browser request crosses the gateway and CAN network, then returns the controller response.
I connected web diagnostics to real controller responses.
Tool / code generation
Strict DBC input becomes deterministic AUTOSAR configuration and C code.
Invalid input stops the pipeline instead of producing unsafe code.
System / platform
The Eclipse OpenBSW base software runs as 26 native Rust crates, held row by row to a pinned C++ upstream.
I closed all 37 mandatory parity rows, backed by 1,653 tests and a reviewed unsafe-code inventory.
