I’m a Senior IT Infrastructure & Network Engineer with 4+ years delivering national-scale enterprise projects across healthcare, banking, government (IKN), education, and transportation. I lead field engineering teams as the primary technical decision-maker during network crises.

I design complete L2/L3 network topologies from HLD to LLD, and I configure and deploy Juniper MX/SRX/EX solutions for routing, firewalling, and switching. I implement BGP routing, OSPF, VLAN, and VPN (IPSec/WireGuard), plus enterprise firewall policy sets across multi-vendor environments.

I also automate and operate infrastructure using Ansible and Python (NETCONF/ncclient), including automated configuration of 80+ Aruba switches to significantly reduce deployment time. For monitoring, I use Zabbix with SNMP traps, custom triggers, and automated alerts to keep networks stable.

Beyond networking, I administer Proxmox and Docker-based platforms, and I integrate IoT and smart-building systems (MQTT/Node-RED/ChirpStack; Honeywell Trend IQ Vision with Niagara) for data and system interoperability. My focus is always reliability, repeatability, and measurable improvements in delivery speed.
