Network & Security Engineer at Finao configuring Citrix NetScaler and GSLB for secure, high-availability applications.

At Finao, I serve as a subject matter expert for Citrix NetScaler across enterprise client environments. I configure load balancing, content switching, SSL offloading, and reverse proxy services, and implement GSLB for high availability across datacenters.

At Lancom Technologies, I provided NetScaler troubleshooting and configuration support, managed SSL certificate renewals and SAML authentication, and administered Microsoft 365 security and related services.

Previously, at HCL Technologies (Project Falck) and Tata Consultancy Services, I configured and supported NetScaler ADC, Gateway, SDX, and ADM environments. My work also included firewall and VPN support, vulnerability remediation, incident resolution, and datacenter infrastructure.
