Council Member
Fedor Shagzheev serves as Founder and Principal Engineer of Sanmark LLC, bringing more than 17 years of experience in telecommunications infrastructure, wireless network deployment, and complex IT systems engineering. He currently operates from Bonney Lake, Washington, where he leads nationwide 4G and 5G network modernization initiatives for AT&T, T-Mobile, and Verizon.
From 2021 to present, Fedor Shagzheev has directed Sanmark LLC through hundreds of telecommunications tower projects across Texas, Oklahoma, Virginia, California, Washington, and Idaho. His responsibilities extend beyond conventional tower installation to include full site integration—configuring radios and baseband units, establishing transport parameters, conducting RF testing, and bringing sites into live carrier networks. Under his leadership, Sanmark LLC generated over $800,000 in gross revenue in 2024, reflecting sustained market demand and the company's strong competitive position. He regularly manages high-priority deployments at federally restricted and mission-critical locations, including Washington State University, Laughlin Air Force Base in Del Rio, Texas, the Toyota Center in Houston, municipal water infrastructure, and facilities near the Texas State Capitol and The University of Texas at Austin.
In his technical capacity, Fedor Shagzheev handles projects ranging from SprintKeep and New Site Build programs to complex Anchor and Rural USA deployments. He frequently receives assignments to previously incomplete or technically challenging sites where resolution requires both deep network knowledge and hands-on RF proficiency. His work encompasses antenna and radio installations, cable replacement and rerouting, equipment and cabinet integration, grounding and electrical upgrades, structural reinforcement, transport configuration, and Site Acceptance Testing to confirm full operational readiness. He has contributed directly to AT&T's FirstNet initiative—a federally funded $6.5 billion program establishing the first nationwide broadband network for first responders—by completing Priority Sites that deliver reliable emergency communications infrastructure.
Since 2020, when Fedor Shagzheev relocated to the United States and began working with North Star Telecom in Texas as a Telecommunications Tower Technician on T-Mobile modernization projects, he has consistently been recognized for technical precision, adherence to safety protocols, and ability to reduce deployment timelines. His transition from IT infrastructure specialist to wireless integration engineer was informed by more than a decade of prior experience in Russia, where he built expertise in virtualization, routing, security, and high-availability network environments—skills that translate directly to modern cellular and backhaul systems.
From 2022 to 2023, Fedor Shagzheev collaborated with New World Telecom as a Telecommunications Engineer and Subcontractor on AT&T and Nokia projects, including high-band C-Band and Department of Defense-related rollouts. He installed and verified high-band radio equipment, ensured new nodes were commissioned on schedule, and resolved integration issues under strict federal and carrier oversight. During the same period, he worked with Beta-Up Corp on AT&T modernization projects, where he was repeatedly assigned to priority and technically complex sites.
In 2023, Fedor Shagzheev provided services to CMS Wireless on Verizon 5G upgrades, replacing legacy equipment with Samsung 5G systems and performing integration testing. From late 2023 through 2025, Sanmark LLC executed demanding infrastructure deployments for Synergy Wireless Solutions, including federal FirstNet, C-Band/DoD, and SprintKeep programs. Since May 2025, he has been collaborating with Niksen Inc. on AT&T's Allagi modernization program across Washington, Idaho, and Oregon, replacing legacy Nokia equipment with advanced Ericsson systems, including FirstNet and 5G+ upgrades.
Before relocating to the United States, Fedor Shagzheev accumulated extensive experience in Russia managing complex IT and telecommunications infrastructure. From July 2008 to November 2015, he worked at Decorative Finishing Materials of the 21st Century LLC (Dom 21 Century LLC), starting as a Communications Engineer and advancing to Information Security Specialist. He managed internal networks, servers, structured cabling, and security measures protecting corporate digital infrastructure.

From January to July 2016, Fedor Shagzheev served as System Administrator at Interior Solutions Manufacture (MIR), overseeing local network infrastructure and supporting engineering teams. Between November 2016 and November 2017, he held a similar position at the microfinance company Chestnoe Slovo, where he transformed fragmented IT systems into a unified virtualized environment using VMware, KVM, Exchange, Postfix, and centralized monitoring tools such as Zabbix and Observium. His work reduced incident response times by more than 30 percent.
From December 2017 to April 2018, Fedor Shagzheev worked as System Administrator at IKS-FIT LLC, supporting distributed fitness centers. From April to August 2018, he maintained internal networks and operational software at Altufyevo-Sport LLC. In April 2018, he joined Pharmadis JSC, a pharmaceutical company, as Lead IT Infrastructure Specialist, where he managed multi-office information systems, directed virtualization and cloud migration projects, and led cybersecurity and reliability initiatives.
In parallel with his IT career, Fedor Shagzheev founded the private enterprise Shagzheev Individual Entrepreneur in 2016–2017, serving as project manager and lead engineer on a major regional telecommunications project under Russia's federal program Elimination of the Digital Divide in the Republic of Buryatia. Working in partnership with PJSC Rostelecom and local authorities, he designed and supervised construction of a fiber-optic communication line connecting the municipalities of Khuzhir, Yengorboy, Shara-Azarga, and Sanaga to the national broadband network. The project, valued at 17.7 million rubles, provided high-speed internet to hundreds of households, schools, and hospitals. PJSC Rostelecom issued an official Letter of Appreciation in December 2017 recognizing the project's quality and technical significance. The Council of Deputies and Administration of the Zakamensky District also formally recognized his professional excellence and leadership in implementing modern telecommunications infrastructure that improved communication services across the region.
Fedor Shagzheev completed a formal Train-the-Trainer program in 2023 under tower safety instructor Kathy Gill, which authorized him to both train and evaluate telecommunications field personnel for Sanmark LLC in accordance with OSHA, NATE, and NWSA industry standards. This certification granted him the responsibility to assess and certify technicians, evaluating their knowledge of safety regulations, fall-protection procedures, high-angle rescue methods, and compliance with federally mandated protocols. In 2025, he renewed and expanded this certification, further strengthening his authority as an independent evaluator of technical competency. Through this role, he routinely reviews technician performance, verifies adherence to safety and operational standards, and determines whether personnel are qualified to be deployed to active telecommunications infrastructure projects.
He has authored two peer-reviewed articles addressing critical challenges in next-generation telecommunications systems. His first article, "Threat Models and Risk Assessment for Autonomous Telecom Systems of the Future," introduces a multi-layered approach to cybersecurity risk assessment in autonomous network environments, combining established standards with dynamic evaluation of AI vulnerabilities, telemetry-based decision-making, and supply chain threats. His second article, "Integration of Satellite and Terrestrial Communication Networks in the Context of Global Internet Access," explores architectural models and international standards for merging satellite and terrestrial networks under the 3GPP and ITU frameworks, analyzing key integration models and evaluating their applicability for digital inclusion, emergency communications, and industrial IoT.
