Managing IT operations across a diversified group encompassing food production, logistics, construction, equipment rental, and media broadcasting. Responsible for full-stack IT infrastructure, security, network optimization, cloud services, AV systems, and enterprise user support.

Responsible for configuring, managing, and maintaining FortiGate and SonicWall firewalls across multiple office and site locations to ensure robust and reliable network security. Tasks include defining and implementing security policies, NAT rules, VLANs, and VPNs (IPSec and SSL), along with enabling IPS, DPI, web/content filtering, and application control. Regularly performed firmware upgrades, log analysis, and threat monitoring while maintaining high availability (HA) configurations to ensure continuous firewall performance. Managed centralized firewall reporting and rule management using FortiManager and FortiAnalyzer tools to streamline security operations and improve visibility.

Also managed Cisco and Netgear switches including configuration of VLANs, trunk ports, LACP (link aggregation), port security, and spanning tree protocol (STP) to support stable and segmented network infrastructure. Proactively conducted network performance tuning, firmware updates, and fault isolation to minimize downtime and optimize LAN efficiency. Ensured end-to-end switching integrity by maintaining standardized port configurations and monitoring traffic flows to detect anomalies or bottlenecks.

Deployed, configured, and maintained wireless access points across offices, warehouses, and remote areas to provide secure and high-performance Wi-Fi coverage. Responsibilities included SSID broadcasting, WPA2/WPA3 security, client isolation, and bandwidth throttling. Administered centralized Wi-Fi controllers for policy enforcement and real-time monitoring. Additionally, oversaw CCTV surveillance infrastructure by installing IP cameras, configuring NVR systems, managing remote access, and ensuring proper video retention policies. Regularly conducted firmware updates and system diagnostics to maintain reliability.

Handled full-scale configuration and administration of IP PBX systems using Yeastar, Grandstream, and 3CX platforms to support business communication workflows. Configured SIP trunks, internal extensions, IVR trees, voicemail, call routing rules, and forwarding policies. Ensured VoIP security and audio quality through codec optimization, NAT and firewall adjustments, and QoS setup. Managed remote workers via softphone/mobile app configuration and maintained uptime through regular backups and monitoring.

Administered Microsoft 365 services including user account provisioning, license assignments, and management of Exchange Online, SharePoint, OneDrive, and Microsoft Teams. Tasks included configuring mailboxes, distribution/security groups, MFA setup, data retention, and anti-spam/DLP policies. Supported end users with collaboration tools, handled onboarding/offboarding processes, and ensured compliance and data integrity through regular audits using Microsoft 365 Admin and Compliance centers.

Additionally managed biometric access control systems for secure entry management across buildings. Configured access groups, enrolled users using fingerprint and facial recognition, scheduled door timings, and integrated access devices with alarm systems. Monitored system activity logs, maintained firmware versions, and worked closely with HR and security teams for access rights management and role-based restrictions.
