Mathematics · teaching · digital products
I study mathematics, teach, and build digital products.
This is a concise, self-authored account of what I am working on and the public work I can explain with evidence.
Now
I am interested in the point where a difficult subject becomes understandable, useful, and possible to verify.
I study mathematics at TU Graz and keep strengthening the foundations behind the work I teach and build.
I create structured mathematics explanations and exam-preparation materials, with attention to German terminology and complete reasoning.
I turn narrow, real problems into small systems with explicit assumptions, human decisions, and results that can be checked.
Selected projects
Not a complete archive and not a technology list. Each project below has a clear problem, a bounded contribution, and something public to inspect.
Mathematics education
Structured mathematics explanations and preparation materials for students in Graz, with German terminology, real task formats, and step-by-step reasoning.
AI-assisted quality control
A public prototype for bounded AI-assisted edits to learning materials: the model proposes, a human approves, and deterministic checks gate the release.
Operational readiness
A public prototype that turns historical yacht-charter instructions into source-linked preparation, exposes missing facts, and runs a deterministic preflight.
About
Demid Valiullin
I live in Graz and study mathematics at TU Graz. Mathematics taught me to make assumptions visible and check what an answer depends on.
I bring the same habit into teaching and product work: understand the real gap first, then build the smallest useful route through it.
This page is not a complete archive. It is the part of my work I can explain, verify, and keep current.
How I prefer to work
Make the problem clear before expanding the solution.
Show the evidence and the limits, not only the polished result.
Keep important decisions under human control.
