I build systems that turn messy information into something useful. I use AI to extract knowledge, organize it into connected data and graphs, and automate the work around it.

The person behind the work

Resume Builder / The Project

This portfolio website is also one of my projects.

I built Resume Builder to keep my career history organized and make it easier to explore. This portfolio shows the project, and the project runs the portfolio you are using.

One system stores my career evidence, creates role-specific résumés and answers recruiter questions.

The project powers the very portfolio that explains it.

Resume Builder / Import

Turning documents and conversation into structured career facts.

I write about my work in my own words, upload my notes, or answer a few questions. AI picks out the jobs, projects and skills and puts them into an organized draft. I check the draft before accepting the facts.

Write naturally. Upload your notes. Review the facts it finds.

Start with your own words

Tell it about your work

I work with spreadsheets. I built a tool that checks each row against a set of rules, so I don't have to keep checking everything by hand.

Resume Builder / Structure

Connecting career records and their supporting evidence.

The system separates my history into jobs, projects, skills, languages and achievements. It connects the pieces: which skills a project used, what it achieved, and where each fact came from. The original passage stays attached, so I can check it.

Connected facts, with the original evidence kept alongside them.

AI-assisted project work: Built a tool applying reusable rules to spreadsheet data

Supported by exact source excerpts

The tool applies reusable rules to spreadsheet data instead of requiring repeated manual inspection. For software projects, ownership, requirements, architectural decisions, experimentation, and review are attributable to Domenik where supported. AI-assisted implementation must not be converted into a claim that he personally handwrote every component.

Resume Builder / Diff

Comparing new information with the existing career records.

New information is compared with what is already saved. The system shows what is new, what changed, what stayed the same and what needs a decision. I review the changes; nothing is automatically removed or published.

New information updates the existing knowledge, after my review.

Resume Builder / Use

Using the same evidence for answers and résumés.

For a question, the application finds relevant facts and follows their connections to understand the context. For a job description, it chooses the experience that fits. Both answers and résumés come from the same saved career history.

One career history. Two uses: answer questions and build tailored résumés.

Resume Builder / Feedback

Seeing which experience recruiters investigate.

I can see which applications bring visitors, what topics they ask about and which résumés they open. This helps me understand what interests recruiters and where I need to explain my work better.

Illustrative activity only. Recruiter questions and applications stay private.

Resume Builder / Stack

The stack behind this portfolio.

The website, database and AI work together. AI helps read what I write, find useful information and explain it. The application decides who can access it, what gets saved and what is ready to share.

AI helps make sense of the information. Reviewed facts stay in the database.
