Herman Fassett

Software engineer in Yakima, Washington.

I build web applications, connect systems that don't yet talk to each other, and improve software people already depend on. I also set up self-hosted services and AI agent tooling.

Alongside my full-time engineering work, I take on selected projects.

A little about me

View my resume

I've worked as a software engineer since 2017, mostly in C#, .NET, Angular, and SQL Server: business applications, integrations, and software that communicates with circuit boards and PLCs. For my own projects I use TypeScript, React, and Cloudflare.

A lot of my work involves understanding an existing system: how people use it, where the data comes from, and what has to keep working when something changes.

At home, I run a lab with Proxmox, Docker, and Home Assistant, and use AI coding tools and agents on my own projects. I also compose piano, orchestral, and chamber music, play viola, and sing.
