## Target role
IT Systems Administrator | Re:Build Manufacturing

## Profile
I build and look after the systems people need to do their work, from a client’s aging office network to shared datacenter infrastructure. My background combines hands-on server and endpoint work, NOC escalations and direct client support, with a habit of making recovery and technical handoffs explicit.

## Curated capabilities
- Windows Server, Active Directory and Microsoft 365
- Networks, VPN connectivity and endpoint troubleshooting
- VMware/Hyper-V, Linux and Azure support
- PowerShell, Python and shell automation
- Recovery verification, monitoring and on-call escalation

## Relevant experience
### Founder / Product Engineer / Systems Lead · Technomancy IT LLC
Current
- Own infrastructure, applications and direct IT support through a referral-based technical practice; clients call me when they need help.
- Design and deploy client systems, build tenant-aware access and support boundaries, and bring in specialists when the work calls for additional craft.

### Senior Systems Engineer / Datacenter Architect · Front Range Internet Inc.
2015-2020
- Ran the NOC and handled escalations through a multiyear engineering tenure and company purchase; later held sole systems-engineering responsibility for about a year, with NOC first-line coverage continuing.
- Migrated workloads from Hyper-V and VMware ESXi into Docker and Kubernetes, upgraded server and firewall infrastructure, and ran SOC 1/SOC 2 audits with operating procedures and recovery evidence.

### Systems / Software Engineer · Office Evolution
2014-2015
- Built shared applications connecting CRM, provisioning, onboarding and service operations across locations.
- Made cross-department handoffs explicit in the tools people used, working with the CEO and CIO on the supporting systems.

### Network & Systems Engineer · PlumChoice / Everon
2012-2014
- Engineered and supported networks, systems and endpoints across managed-service client environments, including on-call support and antivirus services.
- Built diagnostic and support tooling for recurring problems and worked directly with business owners and end users through diagnosis and recovery.

### Infrastructure and Systems Focal · IBM
2010-2012
- Operated shared enterprise infrastructure and coordinated changes, incidents and escalations across application, infrastructure and vendor teams.
- Automated audit and backup workflows and managed virtualization test labs and hosted desktop platforms.

## Product & Engineering Work
### Excell Services | Office and branch infrastructure · Technomancy IT client, Wray, Colorado

- Excell Services was my largest client while I operated in Wray. I replaced or rebuilt legacy servers and employee computers, upgraded the network, and helped bring a satellite location online with VPN, Windows Server and Active Directory access.
- Investigated wasted network costs and secured a one-time $15,000 CenturyLink refund alongside the hands-on infrastructure work.

### Technomancy platform | Making recovery inspectable · Own technical practice and client-operations product

- For the platform behind my support practice, I built delivery tooling that records image identity and deployment status, applies migrations, and checks container health and public HTTP responses.
- A separate restore-verification workflow checks a backup checksum, restores into a disposable PostgreSQL instance and checks table counts, giving recovery work a concrete validation path.

### ProofMark | Identity, documents and signing records · Completed client engineering contribution

- For ProofMark, an AGPL document-signing product, I completed a client contribution designing the workflow across identity, document/PDF fields, routing and audit history.
- I kept security-sensitive state and fallback paths explicit, connecting signing, verification and the associated record across the application and its integrations.
