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. In addition to network operations, I actively manage production hosting and email environments for UFibers, including domain management, DNS administration, Microsoft 365, email routing, cPanel hosting, SSL certificates, WordPress hosting, email accounts, aliases, forwarding rules, SPF, DKIM, DMARC, MX records, and troubleshooting email delivery issues. 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. I have hands-on experience with ZTE C620 and ZTE C650 GPON OLT platforms, MikroTik routing environments, SmartOLT automation, Blesta billing systems, Linux servers, and customer service provisioning workflows.

My focus is on building solutions that are stable, practical, and suitable for real production environments. Available for MikroTik, GPON, SmartOLT, Blesta, Linux administration, DNS management, email infrastructure, hosting support, WordPress migrations, ISP operations, and network troubleshooting projects.
