Self-hosted tools
Small applications that run comfortably on home hardware and stay easy to update, debug, and maintain.
Joseph Kaiser
Small tools, self-hosted systems, and model experiments.
I build lightweight software that is useful, easy to run on my own hardware, and pleasant to maintain.
Most of my time goes into practical web apps, Raspberry Pi friendly services, and LLM evaluation work.
Focus
What I keep building.
The work that keeps pulling me back tends to live at the intersection of useful tools, personal infrastructure, and applied model research.
02
Model evaluation
Fine-tuning and benchmark experiments aimed at understanding where models improve and where the baselines still fall short.
03
Lean interfaces
Web frontends that surface just enough information to be useful, without adding operational weight or visual clutter.
Tools
What I build with.
A tighter look at the stack around the work: the languages I reach for, the runtime pieces that keep things light, and the hardware I like deploying on.
01
Languages
My default toolkit stays close to durable, low-overhead languages that make automation, UI work, and backend experiments easy to keep shipping.
02
Frameworks & runtimes
I prefer compact runtime choices that stay understandable in production: containerized services, SQLite-backed apps, local model serving, and small web frontends.
03
Hardware & deployment
Most of the fun comes from owning the full stack end to end, especially when the software can run comfortably on small machines and stay easy to maintain at home.
Projects
Selected work.
A short list of projects that represent the kind of software I like to make and maintain.
01
ai-chat
A web UI for a locally hosted Dockerized vLLM model, built for private LLM access over a LAN.

myrssfeed
A self-hosted RSS reader for a Raspberry Pi, designed to stay fast, simple, and easy to maintain.

Current focus
Fine-tuning and evaluation work aimed at pushing a model past baseline benchmark results.
