Side Projects & Building
Outside of work, I build web apps and experiment with AI tooling. TypeScript, Next.js, Python, whatever gets the job done. Currently interested in AI agents and how they can fit into testing and security workflows.
R&D Project
Designed and built a Smart Meter Device Lab Stand at work. It is a test rig that hosts 20 device sets with USB port forwarding to remote VMs and automated logging for defect analysis. Made our testing workflow significantly faster.

What I Do Outside Work
I write blog posts and make videos about things I learn. Mostly security topics, IoT projects, and whatever tech I am experimenting with at the time. I find that explaining something helps me understand it better. You can find my videos on YouTube and I post articles here on the blog.
