The role

Aerospace Industrial Engineer

The work

I deploy, test, and optimize the robotic systems behind modern manufacturing. Robots are only useful when they run — my work sits where the hardware, the software, and the people on the floor meet.

Practice

Three disciplines

Robotics Integration

Bringing robotic cells online and keeping them there — parameter tuning, fault diagnosis, and the hands-on troubleshooting that turns a specification into a working line.

Process Optimization

Finding the time and quality left on the table. Cycle-time reduction, method standardization, and operator training that makes improvements hold across shifts.

Systems Testing

Validation before deployment and diagnosis after it — simulation, regression and functional testing, and the documentation that makes results reproducible.

“Validation before deployment, diagnosis after it.”

Documentation that makes results reproducible, and operator training that makes improvements hold across shifts.

Vaultless

A password manager with no vault.

Vaultless was served from this domain until it moved to vaultless.space. If you arrived from a paper oracle printed with the old address, it still works — the square carries the key itself, not a link, so scan or type it at the new address exactly as before. Open vaultless.space

Passwords are derived on demand from a passphrase and an oracle — an ESP32 device or a printed QR square. Nothing is stored, so there is nothing to sync or leak.

OPRFA two-party oblivious PRF over ristretto255 — the oracle never sees the passphrase.

DLEQA proof and a pinned key reject a swapped or tampered device.

Applied cryptography and hardware security are a standing interest.
