A live laboratory for AI systems, web applications,
and digital experiments — built by Matt Dotson.
Built in the field. Tested under pressure. Always evolving.
A full production management system digitizing the heat treat department's paper-based workflow. Operator dashboards, guided test entry, shift handoff reports, MO checklists, run scheduling, pressure point tracking, and fault reference databases — all in one system.
Deploying and evaluating open-source LLMs on VPS infrastructure for personal automation and workflow enhancement. No cloud dependency.
This sandbox is always running. New experiments are always in the queue. Check back.
I'm Matt Dotson — a heat treat operator who moves 20–24 metric tons of steel rail through an induction hardening process every shift. I also happen to build web applications, explore AI systems, and automate everything I can.
DotHotSun.tech is my personal tech sandbox. The name comes from my own — Dot·son split into Dot · Hot · Sun — and the heat reference is very much intentional.
This site exists to demonstrate and test the tools I build. For my professional background, head over to WhatsaMattaDotson.com ↗
