About

The only technical person in the room, usually.

I am a software developer and IT support specialist in Alberta, Canada. Most of my roles have put me in the same position: the single on-site technical contact, the person people find when something stops working. I diagnose it, fix it, and write down what happened, then get back to building.

I keep an even temper when systems are down and revenue is on the line. Security and privacy are defaults in how I set things up, not steps I add later.

Long term, I want to grow inside one company and move into a senior role where I mentor the people coming up after me.

Featured recovery

Every POS terminal in the store, back online the same day.

July 19, 2024 · Staples Store 072

The global CrowdStrike Falcon update put every point-of-sale terminal at Staples Store 072 into a boot loop with a kernel-level stop error. I got manager authorization, traced it to a driver-versus-Windows conflict, and recovered every machine on site without waiting on external IT.

$ assessAll POS terminals down. Boot loop, BSOD on a CrowdStrike driver.$ authorizeManager authorization obtained before touching production machines.$ diagnoseDriver-versus-Windows conflict from the Falcon sensor update.$ boot --winreEntered the Windows Recovery Environment on each terminal.$ del C-00000291*.sysRemoved the corrupted driver file from the CrowdStrike drivers folder.$ rebootTerminal returns to a clean, working desktop.$ statusAll terminals restored the same day. No revenue lost.

No external IT call, no overnight wait, no lost sales. Manager authorization first, then a clean fix, then back to business.
