• Utilize AlgoSec for firewall policy lifecycle management and automation across hybrid and cloud environments.

• Manage and support proxy and secure web gateway solutions including Bluecoat ProxySG (SGOS), BMC, and CAS.

• Implement and support cloud-delivered security solutions including Zscaler ZIA, ZPA, and ZTNA for hybrid and remote access environments.

• Design and support resilient application delivery solutions using F5 VELOS chassis and F5 LTM, GTM, and APM modules.

• Monitor hybrid and cloud network services using Datadog and ensure operational visibility and performance.

• Utilize Cisco DNA Center (DNAC) for network assurance, visibility, and automation.

• Support Forescout for network visibility, device profiling, compliance monitoring, and security posture management.

• Build dashboards, alerts, and telemetry solutions using Prometheus and Grafana.

• Integrate GitHub for version control, peer reviews, and change traceability across network and automation initiatives.

• Develop integrations using REST APIs, SDKs, CLI tools, and GUIs to connect network, security, and cloud platforms.

• Develop tools, services, dashboards, and automation solutions using Python and Django.

• Implement Infrastructure as Code (IaC) practices and automated validation workflows.

• Participate in on-call rotations, major incident response activities, CI/CD-driven change management, and collaboration with global support teams.
