Built from curiosity.
Made for real work.
One founder. A growing collection of tools.
A belief that technology can feel more human.
Space to think.
Something worth building.
Hi, I’m Hass.
I build software for work I understand—and explore the systems I want to understand better.
HassTech brings together practical software, local AI infrastructure, and mechanistic interpretability research. HT Calc grew from real finance workflows. HT Studio explores a more owned, local foundation for AI. Night Light is a research-informed Windows prototype for a calmer display experience.
The projects are at different stages. Their pages separate what’s available, what’s demonstrated, and what is still being developed.
Each chapter
informs the next.
The tools come from lived workflows,
not a list of trends to chase.
- 01
Quality engineering
Learning how complex systems fail—and what it takes to make them dependable.
- 02
Finance & real estate
Working inside the decisions and documents that inspired more useful everyday tools.
- 03
Software & local AI
Building the runtime, interfaces, and integrations that make AI useful on a person’s own machine.
- 04
Research & what comes next
Exploring model internals and turning curiosity into the next practical experiment.
A few things
worth holding onto.
Keep it useful.
Start with a real workflow. Make the next step easier to understand and easier to take.
Keep it inspectable.
Use open standards and source where possible. Show the evidence, and make boundaries explicit.
Keep it human.
Respect a person’s attention, choices, and machine. A tool should leave room for the work itself.
Good conversations
lead somewhere.
Have a workflow to improve, a question about the tools, or an idea to explore?
