Operational Resilience & Infrastructure Strategy Lead

Lamphun, Thailand

khanfan@gmail.com

Professional Summary

Proven Strategic IT Leader with 15 years of experience in high-volume manufacturing, specializing in transforming infrastructure from a reactive cost center into a Strategic Asset and Profit Driver.

Successfully designed and implemented a Triple-Impact framework that drives measurable ROI across three critical domains:

  • Financial Leverage (OPEX): Drives significant cost efficiencies by aggressively optimizing local computing resources through high-density virtualization and server consolidation. This strategy, combined with strict vendor contract negotiation and implementing "Green IT" principles (focusing on sustained OPEX reduction through resource efficiency and minimizing power footprint), ensures every infrastructure investment is financially sound.
  • Operational Resilience: Architected resilient network fabrics and High Availability (HA/DR) solutions for core ERP and factory operations, ensuring best-practice levels of sustained uptime for mission-critical systems.
  • Cyber-Physical Risk Mitigation: Acted as an Operational Risk Manager by leading the convergence of IT/OT security via Zero Trust Architecture (ZTA), specifically focusing on microsegmentation and reducing the overall attack surface.

Expertise includes Network Architecture, Firewalls, Server Management, and disciplined Governance to deliver Actionable Intelligence.
