About

I build full-stack systems end-to-end — from database schema design and backend APIs to frontend UIs, DevOps pipelines, and the Linux servers they run on. I co-founded Admishn, an admissions CRM sold to Davis School District. I currently build production software at Mentors International, deployed across multiple countries.

When I'm not at work, I'm self-hosting things I could pay someone else to host — because owning your stack is worth it.


How I Build

Principle In Practice
🆓 Free & Open Source First Prefer free APIs and self-hostable tools over paid lock-in
🏠 Self-Host When It Makes Sense Own your stack, own your data
♻️ Code Once, Reuse Everywhere Boilerplates, libs, pipelines — write it right the first time
🎯 Simplicity Is the UX If you need training, the design failed
🔒 Security Without Friction OAuth over passwords, public/private endpoints always separated
🗃️ High-Quality Data Clean schemas, clean migrations — accessible but never messy
🤖 AI as a Multiplier Claude Code to iterate fast; AI amplifies craft, doesn't replace it
📊 Data-Informed, Not Data-Driven Dashboards empower judgment — they don't replace it
