Demid Valiullin / Graz, Austria

Software engineering with a mathematician’s eye for detail

I’m a mathematics student at TU Graz who builds and tests software in Python and TypeScript. I like turning fuzzy problems into small, useful tools.

I’m looking for my first Working Student, part-time, or internship role in software engineering. I’m open to on-site or hybrid work in Austria and remote roles where Austria-based hiring is possible.

Start with the problem. Build what helps. Test what matters.

I start with the person who needs the result and the decision they need to make. Then I build the simplest version that solves the real problem.

Understand the problem
I ask what the result is for, what information it needs, and what could go wrong.
Build a working path
I use Python and TypeScript to connect the inputs, the decision, and clear failure states.
Test and improve
I automate repeatable checks, review the result by hand, and use feedback to sharpen the next version.

Selected projects

Projects I can show and explain.

AI tools helped with parts of these projects. I chose what to build, shaped the workflows, tested the results, and decided what was ready to publish.

Decision support and QA automation

TenderVerdict Next Gen

TenderVerdict helps a supplier review public tenders. It compares notice metadata with a supplier profile, explains each match, and keeps the first decision local.

Result: 128 Python tests and 20 native contract checks
What I did: I decided how the tool should qualify a notice, set the release scope, and checked the Python and Swift builds before submitting the project.
Built with: Python, Swift, SwiftUI, RevenueCat Test Store
Status: Hackathon prototype; not released on the App Store or used in production
Public materials: Devpost entry, competition source branch, and demo video.

Quality control for learning content

LessonProof

LessonProof is a prototype for safer AI edits to teaching materials: AI suggests a change, a person approves it, and automated checks stop a bad release.

Result: 42 automated tests
What I did: I designed the approval flow and release checks, then reviewed the implementation against 42 automated tests.
Built with: TypeScript, React, Node.js
Status: Public prototype
Public materials: Runnable prototype and public source code.

Source code

Source-linked preparation checks

Neja Ready

Neja Ready turns past yacht-charter instructions into a practical checklist. It links each step to its source, calls out missing information, and runs a preflight check.

Result: 79/79 verification checks
What I did: I defined what the checklist had to cover and how it should flag gaps, then verified the public prototype against all 79 checks.
Built with: TypeScript, Node.js
Status: Public prototype
Public materials: Runnable prototype and public source code.

Live prototype Source code

Mathematics education

Demid.Math

Demid.Math is where I teach mathematics in Graz. I create structured explanations and exam-preparation materials with German terminology and full worked solutions.

Result: Public website, channel, and teaching videos
What I did: I choose the topics, prepare and record the material, publish it, and keep the project running.
Built with: Curriculum design, video, bilingual communication
Status: Active teaching project
Public materials: Website, Telegram channel, and mathematics videos.

Early in my software career. Serious about the work.

Demid Valiullin

I live in Graz and study mathematics at TU Graz. I’m looking for my first software engineering role, and I use public projects to show how I think, build, and test.

In those projects I’ve used Python, TypeScript, REST APIs, SwiftUI, and automated validation. When a problem calls for an unfamiliar tool, I’m comfortable learning it.

Running Demid.Math has also taught me to take responsibility for a public service, explain hard ideas clearly, and improve through direct feedback.

What teammates can expect

Ask questions before a wrong assumption turns into rework.
Share work early enough for feedback to be useful.
Test the risky parts and explain the trade-offs.
