About
A generalist working the seam between systems and the reasons for them.
Business Informatics student working across software engineering, artificial intelligence, and product design.
01 — Who I am
A little about me.
I'm Denis — a Business Informatics student in Vienna, drawn to the space where systems meet the people and decisions they serve. The degree pairs computer science with information systems and management, and I've come to read it less as two subjects than as one skill: moving cleanly between how something is built and why it's worth building.
That interest shows up in the work I gravitate to. I like problems that sit at seams — an AI model and the humans who have to trust it, a curriculum and the students who plan around it, a raw dataset and the business decision it's meant to inform. The interesting part is rarely the isolated piece of technology; it's the translation.
In practice, I move between roles. I design and build software, I train and evaluate small machine-learning systems, I think about products and the market around them, and I care a great deal about how the result looks and feels. I'd rather be genuinely versatile than narrowly specialised too early.
02 — Beyond the work
The parts that don't fit on a CV.
Hobbies, habits, and a couple of things I'm quietly proud of. Drag, swipe, or use the arrows.
03 — What I value
How I like to work.
Honesty over polish
A tool that's clear about what it doesn't know earns more trust than one that hides its uncertainty behind a confident interface.
Craft in the unglamorous parts
Most of a product's quality lives in the data model, the edge cases, and the error states — the parts no screenshot shows.
Restraint as a discipline
Knowing what to leave out is the harder half of design. I aim for work that feels considered, not crowded.
Translation as a skill
The most useful thing I do is move a decision cleanly between the people who think in systems and the people who think in outcomes.
