In the current role as a Technical Support Engineer, responsibilities include designing, implementing, and maintaining wireless network infrastructures, primarily focusing on Wi-Fi networks and cellular backhaul systems. The full deployment process is managed remotely, from RF site surveys and frequency planning to setting up wireless controllers and access points, using tools like Ekahau Site Survey and Cisco Wireless Controllers.Network monitoring is conducted using software tools such as SolarWinds Network Performance Monitor, PRTG Network Monitor, and Wireshark to monitor traffic, analyze performance, and troubleshoot issues in real time.Security is a significant part of the responsibilities. Regular configuration and management of Palo Alto firewalls, Cisco Firepower, OpenVPN, and IPSec tunnels are performed remotely to ensure data security across wireless connections. WPA2-Enterprise is implemented for network authentication, and regular vulnerability assessments are conducted using Nessus.On the operational side, collaboration with cross-functional teams is essential, working closely with hardware and software engineers to integrate wireless systems into the overall network architecture. Network documentation and reporting are handled using Visio, Jira, and Confluence, creating detailed logs of network configurations, performance stats, and incident reports.One of the biggest achievements was optimizing the wireless network's performance by 30% by fine-tuning RF channel allocation and implementing advanced QoS rules for high-priority traffic like VoIP and video conferencing. Successfully managed the migration of legacy systems to a more modern, cloud-based wireless infrastructure using AWS, which increased overall scalability and reduced operational costs.Led the deployment of a secure VPN solution for remote access, enhancing network accessibility while maintaining data security.
