Software engineer who ships practical tools end to end - from machine-learning pipelines to deployed, self-hosted web apps.

About me

A few things I like:

• Traveling
• Rock climbing
• Hiking
• One Piece
• Making tools that make life easier - without paying for a subscription to some service that slowly gets worse over time
• Bubble tea

👋 Hey, I'm Quang! I recently earned a B.S. in Computer Science from Western Governors University - actually my second degree, pursued specifically to learn how to build cool things.

My path into software started at a previous job full of insanely repetitive tasks, so I taught myself automation. My first internal tool - an Excel VBA macro that turned a multi-minute task into a two-button click - saved real time every day, and that hooked me on the field for good.

Since then I've built and shipped full-stack apps, a multi-model computer-vision pipeline, and a microservices backend. I like owning a problem from idea to deployment. (Basically, I wanted to work les--I mean, more efficiently. Work smarter, not harder!)

Projects

🔐 My web apps share a single sign-on: one account works across Splitpush, TravelBin, and Itinerary Agent through a self-hosted Keycloak (OAuth2 / OIDC) instance.
