Systems Architect | AI-Native SaaS | Distributed Systems | Global Technology Leadership

I build large-scale systems that connect technical architecture, organizational scale, and business automation. Over 15 years in software engineering, I’ve led projects spanning Meta’s encrypted messaging infrastructure (Messenger & Instagram Direct), real-time anti-fraud and telemetry platforms at F5/Shape Security, and full-stack IoT and blockchain-integrated hardware ecosystems. My experience covers the entire spectrum from low-level systems to SaaS startup execution.

Having operated across the **U.S., Australia, and China**, I bring deep cross-cultural experience in leading distributed engineering teams and scaling products globally. I thrive at the intersection of **system design, product strategy, and organizational execution**, bridging technical depth with business outcomes.
