Key Achievements

Japan's first Cyber Fusion Center — $25M invested, ROI > 70%. Designed and ran it at Accenture using my own framework, Adaptive Defense; against a $25M investment it returned over 70% ROI with full payback in three years, and turned security governance from a cost center into a P&L-generating structure.

Cross-border GTM acceleration (Israel → Japan). For Israeli deep-tech startups and their VCs, time from market entry to signed contract compresses — the gap between Israeli speed and Japanese corporate governance turned into customer trust and faster conversion.

"Most Valuable Engineer," worldwide (FireEye President's Club, 2013). As a founding member of FireEye Japan, introduced dynamic sandbox analysis to the market and built the sales-engineering function from zero.

Professional Summary

For thirty years — since starting as a technical translator in 1996 — foreign technology has earned the trust of Japanese enterprise buyers through my work, and the path from first meeting to signed contract has grown shorter. My rare edge: I turn strict governance and control — the very things that usually slow a deal — into the reason a cautious enterprise says yes, and into faster go-to-market. And what I advocate, I build myself.

The track record is cumulative, not coincidental: FireEye's worldwide "Most Valuable Engineer," Accenture's $25M Cyber Fusion Center, and today's cross-border advisory are steps in one line of work — making complex security legible to the people who sign the deals, and being a candid, rigorous sounding board that lowers the load of executive decisions. It runs in real time, across cultures and languages (Pearson VERSANT Sentence Mastery: C2).

Career Evolution

Each phase enabled the next: translation led into forensics and packet-level analysis; that depth enabled converting cyber risk into P&L and ROI; a period away to care for family sharpened how I read executives; today the focus is improving how enterprises actually make decisions.

Professional Experience

Applied R&D — Noēma (2024 – Present)

Cognitive security at the developer's endpoint — a working proof-of-concept that intervenes at the human moment (e.g., pasting AI-suggested code): an on-device model reads intent and a deterministic, human-written policy decides allow / nudge / block. All analysis runs locally — the text examined and its results never leave the device (zero exfiltration).
