About Me

Bridging Deep Tech with Real-World Impact

With over 25 years spanning technical consulting, operations management, and enterprise training, I bring a rare blend of hands-on engineering depth and instructional excellence. My journey began in electrical engineering and evolved into a specialisation in network security, zero trust architectures, and large-scale enterprise training delivery.

As a Founder, Technology Consultant, and now Senior Technical Trainer at NTT Global Networks, I've consistently translated complex technologies into actionable knowledge — helping teams perform at their best in mission-critical environments.
