About Me

I strive for simple but effective user experiences, clear code, and performance across the stack. The best software feels effortless and sits on straightforward, readable logic.

Technical Support & Consultant

I am often the first call when something technical fails: apps, accounts, endpoints, or networks. I diagnose under time pressure, write docs people can follow, and train non-technical colleagues so they can keep going without me. As a technical consultant, I bring that same approach to a client engagement: troubleshooting analytics, tag management, and CRM integrations, keeping compliance requirements like GDPR/CCPA in check, and equipping their non-technical team to make site updates confidently on their own.

Life Offline & DIY

DIY-er

I love getting my hands dirty with home renovation. From routing new ethernet cables through multiple rooms and replacing windows, to upgrading bathrooms and kitchen cabinets.

One Man Auto Shop

An enthusiast for working on cars. I enjoy the mechanical complexity (and cost savings) of fixing and maintaining vehicles myself.

Home Lab & AV

Home server, structured Ethernet, routing and wireless, plus a nine-channel theater I designed and calibrated. I also assemble and repair PCs and chase down display, projector, and connectivity faults.
