Interests

When I have time to myself, I enjoy a bike ride by the lake or ripping through the streets on an electric skateboard. That was until Covid hit, now I am a at-home karaoke enthusiast!

On the creative side, I am passionate about digital photography where I upload to a public photo sharing website for crowdsourcing.

On the technical side, I enjoy hands-on engineering projects involving computers, phones, tablets, appliances, and other electronics. I regularly build and upgrade desktop PCs, disassemble systems for repair, replace components such as RAM and storage, diagnose hardware/software issues, and experiment with new operating systems, applications, and connected-device workflows.
