Wireless Design, Deployment & Troubleshooting
• Designed, deployed, and maintained enterprise-grade wireless LAN solutions using Cisco WLCs and APs (802.11a/b/g/n/ac/ax), supporting both indoor and outdoor environments.
• Performed wireless site surveys and heatmap analysis using tools like Ekahau and Cisco Prime to ensure optimal RF coverage and signal strength.
• Conducted detailed packet-level troubleshooting using Wireshark and Cisco embedded packet capture (EPC) for latency, roaming, and authentication issues.
• Troubleshot WiFi connectivity and performance issues including DHCP delays, client roaming failures, and channel interference.

Wireless Security & Authentication
• Implemented wireless security protocols including WPA2/WPA3, 802.1X, EAP, and RADIUS-based authentication in enterprise environments.
• Configured Cisco ISE for AAA, role-based access, and guest portal access across wireless deployments.
• Ensured compliance with wireless security best practices through regular audits and posture validation.

Monitoring & Optimization
• Utilized Cisco DNA Center and Prime Infrastructure for wireless network monitoring, client analytics, and performance optimization.
• Tuned RF parameters (Tx power, channel plans, RRM) and adjusted SSID configurations to improve network performance and reduce interference.
• Analyzed roaming patterns and optimized controller/AP settings for seamless Layer 2/Layer 3 roaming.

Upgrades, Patching & Compliance
• Performed wireless controller upgrades, AP firmware management, and security patching with minimal downtime in production networks.
• Conducted network audits and configuration compliance reviews to align with enterprise IT standards and Arista best practices.

Collaboration & Escalation Handling
