I build reliable enterprise networks and solve complex IoT, security, and connectivity issues.

At TP-Link ESC, I orchestrate advanced troubleshooting for Omada SDN Controllers, JetStream switches, and SafeStream gateways. As the L3 escalation point for B2B customers, I design solutions for multi-VLAN architectures and secure IPsec/VPN site-to-site tunnels.

I work directly with global R&D and engineering teams to identify firmware anomalies, validate patches, and improve intelligent hardware reliability. By optimizing NAT, DHCP, and routing, I maintained 99.9% operational uptime across enterprise customer networks.

Previously, I supported the global Google Nest ecosystem at Sykes during the rollout of Matter and Thread, resolving complex IoT interoperability, RF interference, and network topology escalations. I also bring extensive banking infrastructure experience from managing POS terminal lifecycles, transaction traffic, PCI-DSS compliance, fraud prevention, and payment investigations.

I'm fluent in Romanian and Italian, with advanced professional English, and I enjoy applying my background in enterprise networks, smart-home automation, diagnostics, and security to technically demanding environments.
