Sean R. D.- Springfield, Missouri - "DIY Greybeard Hacking His Homelabs Since 1993" I am a hybrid IT field technician bridging the gap between complex network engineering and frontline retail operations. With over 25 years of hands-on experience—dating back to building experimental home labs and configuring DMZ security perimeters in the early 2000s—I specialize in acting as the ultimate "smart hands" for remote NOCs and Level 3 engineering teams. Beyond the hardware, I am a former multi-unit retail operations leader and Director of Business Development. I know how to execute critical infrastructure upgrades, network cutovers, and POS deployments with zero disruption to an active sales floor. I don't just follow the deployment script; I troubleshoot the exceptions, speak the same language as your remote network engineers, and communicate flawlessly with local store management. When your deployment goes sideways, I am the tech who reverse-engineers the problem, reads the documentation, and gets the site back online. Core Competencies & Capabilities Retail IT & POS Systems: Deep expertise in Point of Sale hardware/software environments, having spent years managing high-volume retail locations (Verizon, T-Mobile, UScellular). I understand the backend control room and the frontend customer experience. Network & Infrastructure: Advanced routing, switching, and wireless remediation. Comfortable navigating Layer 2/3 configurations, Active Directory environments, and deploying enterprise-grade Wi-Fi and Digital Signage networks. Systems Architecture: Creator of autonomous, edge-to-cloud data pipelines (Python, GCP, Node). I understand network traffic, asynchronous data flows, and secure API integrations from the code level down to the physical hardware. On-Site Project Management: Capable of leading complex multi-site rollouts, coordinating with remote project managers, and ensuring strict compliance with operational protocols and deliverables. My Approach I treat every service call as a critical business operation. You can expect executive-level communication, meticulous documentation, and an absolute commitment to getting the system fully operational. If it has a circuit board or a network interface, I can deploy it, configure it, and fix it.
