What I'm looking for

I’m looking for a role where I can lead data center network transformations and perimeter security with hybrid cloud connectivity—combining hands-on routing/firewall work and Python/Ansible automation to deliver reliable, zero-downtime cutovers.

I’m a Senior Network Engineer with 10+ years of enterprise and financial-sector DC experience, specializing in full-lifecycle network transformation. I’ve led BGP/OSPF/VXLAN/EVPN spine-leaf architecture work, perimeter security, and hybrid cloud connectivity with a relentless focus on reliability.

At UBS, I served as a primary architect and lead delivery engineer across 8+ international DC sites (EMEA, APAC, Americas). I migrated 200+ external-facing VPN/Extranet/MPLS connections and 500+ network devices from legacy Cisco/NetScreen to Arista EOS and FortiGate NGFW with zero unplanned downtime.

I bring deep hands-on expertise across Juniper SRX, FortiGate SD-WAN, Palo Alto, Cisco ASA, F5 BIG-IP, Microsoft Azure hybrid connectivity, and Python/Ansible-based network automation. I also act as an automation SME, contributing Python/Ansible workflows that reduced repetitive provisioning change cycle time by ~40%.
