Home
I am Don A. Sands III, an IT professional with a background in support operations, systems administration, network engineering, regulated laboratory systems, and practical problem solving across Windows, Linux, cloud, and on-prem infrastructure.
This site serves two purposes: a professional resume for my technical career and the home page for DASIII LLC, my startup focused on dependable computer support, network services, and small business technology consulting.
I work best where the problem is real, the environment matters, and the solution has to be maintainable after the initial fix. That means clear troubleshooting, good documentation, secure defaults, and systems that people can actually operate.
Resume
Professional Summary
IT Support Specialist and Systems Administrator with experience supporting enterprise users, regulated laboratory platforms, managed service environments, Windows infrastructure, Microsoft 365, endpoint support, networking, security tools, backups, and documentation. Navy veteran with a background in readiness, training, operational discipline, and technical support at scale.
Current Role
At BioAgilytix, I support and administer critical IT systems for a large user base, including Windows environments, Microsoft services, Watson LIMS, MesoScale Discovery Workbench, and other laboratory technology platforms. My work emphasizes response quality, data integrity, GxP awareness, documentation, and operational continuity.
Prior Experience
As a Remote Support Engineer at PJ Networks, I provided managed IT support across more than 1,300 devices and over 80 businesses. The role required fast triage, remote troubleshooting, customer communication, network administration, backup awareness, and consistent documentation across varied client environments.
My career began in the United States Navy as a Hospital Corpsman and later in Staff Education and Training at NMC Portsmouth. I supported readiness, trained staff, delivered technical assistance to thousands of users on computer-based training systems, and earned multiple awards including Navy and Marine Corps Achievement Medals.

Projects
My personal lab is where I test, break, rebuild, and document the systems that shape my professional judgment. It includes virtualization, network segmentation, server administration, backups, DNS filtering, firewall policy, Linux services, and self-hosted tools.
Current Technical Focus
- Proxmox virtualization, Windows Server, Linux services, and backup architecture
- UniFi networking, firewall replacement, VPN access, DNS filtering, and VLAN design
- Self-hosted infrastructure intended to reduce dependency on closed ecosystems
- Documentation, repeatable builds, and operational processes that survive beyond the first install
How I Approach Technical Work
I do not consider a fix complete just because the alert disappears. A complete fix should explain what failed, why it failed, how to confirm recovery, how to prevent recurrence when practical, and what tradeoffs were accepted.
