I have extensive experience configuring and maintaining network hardware, including routers and switches from vendors like Cisco and Juniper. I am proficient in setting up VLANs, routing protocols like OSPF and BGP, and ensuring optimal network performance. My hands-on experience includes troubleshooting hardware failures, performing firmware updates, and ensuring compliance with security standards. I also have a strong understanding of network design principles, which allows me to optimize hardware configurations for scalability and reliability.

In an ISP environment, I prioritize rapid response and clear communication during network outages. I start by identifying the root cause using monitoring tools and logs, then implement a resolution plan, whether it involves rerouting traffic, replacing faulty hardware, or applying patches. I ensure minimal downtime by following established incident management protocols and keeping stakeholders informed. Post-resolution, I conduct a thorough analysis to prevent recurrence and update documentation to improve future response times.

Network monitoring tools like Nagios, PRTG, and SolarWinds are critical for maintaining ISP network health. I use these tools to monitor bandwidth usage, detect anomalies, and ensure SLA compliance. By setting up alerts for thresholds like latency spikes or packet loss, I can proactively address issues before they escalate. These tools also provide valuable data for capacity planning and performance optimization, ensuring the network can handle growing traffic demands while maintaining high availability and reliability.

Ensuring network security in an ISP environment involves implementing firewalls, intrusion detection systems, and regular vulnerability assessments. I enforce strict access controls, use encryption for sensitive data, and keep all systems updated with the latest patches. Additionally, I monitor traffic for suspicious activity and educate users on best practices to prevent phishing or malware attacks. Regular audits and compliance checks ensure adherence to industry standards like ISO 27001, safeguarding both the network and customer data.

I have hands-on experience deploying and troubleshooting broadband technologies, including DSL, fiber, and cable. For DSL, I configure DSLAMs and troubleshoot line quality issues. With fiber, I handle GPON setups and ensure proper signal strength. For cable, I work with DOCSIS standards and resolve issues like signal interference. My troubleshooting approach involves analyzing signal metrics, testing hardware, and collaborating with vendors to resolve complex issues, ensuring customers receive reliable and high-speed internet services.
