Systems, security, and engineering work in practice.

Lev Kantorovich is a systems and security engineer whose work has centered on Windows internals, endpoint agents, network filtering, telemetry, diagnostics, and reliability.

The current direction extends that foundation into AI-assisted engineering: bounded agentic workflows, control-plane design, orchestration, validation, evidence packets, and human approval boundaries.

The through-line is simple: instrument before guessing, validate before claiming, design for failure, and keep humans in control of consequential automation.
