I build systems, theories, and tools — and I release them freely.

Everything here is open‑source, license‑free, and pay‑what‑you‑want. My goal is to create work that’s genuinely useful, insightful, or empowering — and put it in the hands of anyone who needs it.

If my work helps you, you can support my livelihood through Cash App at $DonSemsey. If not, take it freely with my blessing.

Mission

Semsey Technologies is my personal research and development studio. I explore how systems behave — cognitive systems, software systems, human workflows — and I build tools, theories, and architectures that make those systems clearer, more predictable, and more humane.

Everything I create is:

Transparency & Expectations

I build a lot — theories, tools, experiments, prototypes, and occasionally full products. Some of it is polished. Some of it is experimental. Some of it is held together with duct tape and a good attitude.

Because I work independently and release everything openly:

I label what’s stable, experimental, or mostly broken. I document what I know and what I’m still figuring out. I improve things when I can. I never pretend something is more mature than it is.
