About Me

I work across the whole stack, but most of my experience is on the back end — ASP.NET services over MSSQL, plus Express or FastAPI when a project needs them.

Most of what I build is used at work every day: compliance documents going through review, patients managing their memberships, field teams filing leave from their phones. So I build for daily use — data you can trust, apps that keep working when the connection drops, and screens that stay easy to read.

Recently a lot of that work has involved AI: a medical assistant running on a self-hosted language model, a realtime voice coach, and transcription pipelines. When the data is sensitive, I run the model on your own server so nothing leaves it.
