01 Profile

Technical thinking grounded in real operations

I connect the system, the user, and the work around them.

My background spans POS support, customer-specific interface setup, website maintenance, responsive web work, accurate operational records, inventory control, and cross-team coordination. That mix helps me troubleshoot with context instead of treating technology as an isolated box.

At Unitec, I extended that experience through Level 8 study in mobile and wireless communications, cloud, cyber security, IoT, data science, machine learning, business intelligence, and IT project management.
