About me
Technical depth with a service mindset.
I work across the full day-to-day IT environment: desktops, laptops, Microsoft 365, networks, wireless systems, printers, mobile devices, endpoint security, onboarding, offboarding, and technical documentation.
My strongest work happens where technical troubleshooting, infrastructure ownership, and user support meet. I enjoy finding gaps before they become outages, improving unclear processes, and leaving systems better documented than I found them.
01
Own the outcome
Follow issues through from discovery to resolution and documentation.
02
Reduce complexity
Make technology understandable for both technical and non-technical users.
03
Build for supportability
Create repeatable systems, naming standards, records, and practical controls.
Core expertise
Hands-on support across the modern workplace.
A practical combination of systems administration, infrastructure, security, and customer service.
Network Infrastructure
Switches, firewalls, wireless, TCP/IP, DNS, DHCP, VLANs, VPN connectivity, and structured troubleshooting.
Endpoint & User Support
Windows devices, deployment, imaging, printers, peripherals, mobile devices, remote support, and lifecycle management.
Endpoint Security
Microsoft Defender, Bitdefender GravityZone, patching, secure configuration, alert review, and cybersecurity awareness.
Documentation
Asset inventories, network maps, patch-panel records, SOPs, knowledge-base articles, and change documentation.
IT Operations
Ticket prioritization, vendor coordination, onboarding, offboarding, procurement, licensing, and continuous improvement.
Selected projects
Examples of proactive IT ownership.
These summaries are intentionally generalized to protect organizational and security-sensitive information.
01
Network modernization
Recovered and documented an unmanaged multi-switch wireless environment
Identified gaps in a third-party handover, restored centralized management, standardized device naming, mapped access points and switch connections, and created maintainable infrastructure records.
Result
Improved visibility, supportability, and control of the environment while reducing future troubleshooting time.
02
Microsoft 365 administration
Improved access, collaboration, and administrative controls
Supported Exchange Online, Teams, SharePoint, Entra ID, account provisioning, permission reviews, shared resources, email troubleshooting, and user guidance.
Result
Clearer ownership, faster issue resolution, and better alignment between technical configuration and organizational needs.
03
Security & endpoint operations
Strengthened endpoint protection and operational consistency
Administered endpoint protection, reviewed alerts, supported patching, standardized support practices, and helped users follow practical cybersecurity best practices.
Result
More consistent protection, improved response visibility, and reduced risk from unmanaged or poorly maintained endpoints.
Technical insights
Practical ideas from real-world IT work.
