IT Service Provider | Small Business Owner | Field Technician | Cybersecurity Professional & Researcher | Homelab Tinkerer
I run Pacific Northwest Computers, an IT services business in Vancouver, WA serving the SW Washington and Portland metro area. With 20+ years in the trenches of small business IT, I build the tools I actually use day-to-day. From Windows deployment automation and system auditing scripts, to self-hosted infrastructure, and embedded security projects. Everything here comes out of real client work or my own homelab. www.jonpienkowski.com
