Linux
My pride and joy. I don't really need it, but it taught me how computers work, how little I know, and how much I still have to learn. I run NixOS btw.

Building Hermie: deterministic dental insurance verification, done before the front desk opens.
Right now, I'm
- building
- Hermie, deterministic dental insurance verification, written straight into the practice's PMS.
- running
- Onsite infrastructure and PMS integration at NetFusion Consulting.
- shipping
- Small tools on the side, on Cloudflare Workers, FastAPI, and NixOS. See the work.
- studying
- At SFSU, class of 2030.
Hermie
Dental offices lose hours every morning on insurance hold music. Hermie verifies every scheduled patient overnight and writes the full benefits breakdown into the chart before anyone walks in.
- How
- Clearinghouse check first, payer website second, an AI voice agent calls the payer last. Each step only fills what the one before it missed.
- Where
- Writes straight into Dentrix, Eaglesoft, and Open Dental through a bridge that runs inside the office.

What I know
Docker
I was too cheap to pay for a Windows key, so I watched a ton of YouTube and learned Docker and networking. Now I have a solid base for security-minded, technical work.
Audio engineering
I mix audio for my school's theater. I also mix audio for my church.
Web design
I want to go to business school, or at least start companies. Selling web design to small businesses lets me build those skills with little risk.
