I’m a Network Operations Engineer with 2.5+ years of hands-on experience supporting ISP network operations, especially in incident management, routing & switching, and 24/7 network monitoring. I’ve handled monitoring for 1,700+ active customers and 150+ network devices, maintaining strong SLA performance while troubleshooting connectivity, performance, and infrastructure alerts across residential and SME networks. I’m also comfortable working end-to-end across access and transport environments, including MikroTik and Huawei platforms, GPON/EPON OLTs, Huawei RTN microwave links, and fiber optic support (OTDR testing and fusion splicing). Alongside troubleshooting with tools like Zabbix/PRTG and Wireshark, I automate monitoring and alerting (including Telegram bot workflows) and use Python to improve operational visibility, speed up response, and reduce manual effort.…I’m a Network Operations Engineer with 2.5+ years of hands-on experience supporting ISP network operations, especially in incident management, routing & switching, and 24/7 network monitoring.
