Hire the Best Multi Router Traffic Grapher (MRTG) Specialists

Telecommunications and Network Engineer with over 10 years of practical experience in ISP operations, FTTH networks, GPON systems, MikroTik RouterOS, Linux servers, DNS, hosting, and email infrastructure. My background comes from working in real ISP environments where network stability, customer connectivity, and service availability are part of daily operations. I currently work with an FTTH network serving more than 500 active subscribers and manage the systems required to keep services running reliably. I am currently involved in the operation and development of the UFibers platform, supporting ISP infrastructure, customer provisioning systems, billing integrations, network operations, DNS services, hosting environments, and customer support systems.

This hands-on experience comes from operating live business systems and customer-facing services rather than lab environments. Recently received a 5-star Upwork review for DNS, Email Infrastructure, and Technical Operations support, with client feedback highlighting quality, problem-solving, and technical expertise. My daily work includes customer provisioning, PPPoE service management, network troubleshooting, outage investigation, OLT administration, DNS management, email infrastructure support, hosting administration, and maintaining operational systems used by both customers and support teams.
